IMPORTANT: Don't laminatc one-of-a-kind documents unless you are surc of you laninating skils and can afford to damage or ruin the document. Don't laminate valuable items such as stamps, baseball cards, autographs, or other collectibles because the value of such items can be destroyed by lamination. Collectors generaly value these kinds of items only in their original state. Remember that you cannot laminate thermal paper, such as typical fax paper, because it is activated by heat and will turn black. Aiso, remove paper clips and staples because they can damage the rubber rollers.Be carefiul about laminating anything that will be affected by hcat. For example, the colors in crayon drawings may run together or be smeared, especially if the crayon layer is heavy. Light crayon drawings may not be affected, but

1-2 FEATURES & BENEFITS

Your new machine has many standard features and accompanying benefis that set it apart from other laminators:

• Pneumatic power opens or closes the laminaring and pull rollers and gives you precise and independent control of roll pressure. A compressor is buit in so that shop air is not required.
• Removahle heat shoes are Teflon coated to reduce film abrasion. They are casily unplugged and removed to clean or replace the laminatimng rollers.
• Built-in retractable shitters save an enormous amount of cutting time by mimming away side scrap during the lamination process. The two heads can be adjusted independently with great
• Dual tension knobs (clutches) for each supply roll mandrel are easy to use and provide as litle or as much tension as needed to keep work flat and wrinkle-free.
• Forced air cooling is essential when running thickor films, because the lanmination needs to be cooled to get good resuts. These machines have a row of fans mounted above and below the fim as it leaves the laminating rollers.
• Lasy access controls arc conveniently located and grouped for effective operation.
• The safety guard is built into the feed tray, and the machine wilnot run without the feed thay in place. Stop buttons on both sides of the machine front and back contribute to a complete safety package. The back rolers are also guarded.
• Both upper and lower rolers are driven to minimize the wrinkling or curing that can occur when only one roller is driven.
• A removable bottom iiler bar makes it much easier to thread fim.
• Standard precision feed tray has both left and right side guides and is adjustable from a few inches to the width of the machine.
• A rugged steel stand is included. Domestic orders are shipped on the assembled stand, while Overseas orders are shipped with the stand disassembled, unless otherwise specified.
• All four ruhber rolls are interchange a hle. If a laminating roller should become damaged it is possible to replace it with a pull roller.
• Made in the USA means better quality , service and parts availability.

L5 Prnciples Of Operation

The Industrial Series laminators operate by pulling film with a thermally-activated adhesive over a heat source and into a set of laminating rollers. Fiim from the supply rolls passes over heat shoes to activate a polyethylene adhesive layer on the film. It then passes through rubber rollers t0 apply pressure and bond the filn to the item being laminated. The adhesive is pressed into the ink and fibers on the surface of the paper. The strength of the lamination bond can be checked by cutting a large "X'" on the surface of a laminated sample with a sharp blade. Use the tip of the blade to pry up one corner of the "X". Grab that comer and pull up the fim. Ink and/or paper fibers coming up with the layer of fim indicates a good adhesive bond. If the film comes up too easily, with no ink or paper, the lamination was probably done at too low a temperature. Check the instruct i cns that may have come with your laminating film and/or the lamination temperature chart in secticn 5~6. Please note that when doing an X-test on glossy (coated) paper, a good X-test will pull up ink only. The film should not come up easily. When laminating material that is not glossy (uncoated), the paper is often nore fibrous and a good X-test will yield ink and paper fibers coming up with the fim.

1-6 LAMINATING FILM

Most thermal laminating fim consists of two layers: a base of polyester and an adhesive layer of polyethylene. The polyester layer forms the harder outer surface of the filn and does not melt at laminating temperature. It provides rigidity and protection for your laminated items. The greater the polyester content, the higher the level of protection, rigidity and luster. The polyethylene layer melfs at laminating temperature and bonds the film onto the subject material under the pressure of the laminating rollers. As an X-test demonstrates, the adhesive is pressed into the paper and fills irregularities in the surface. The proportion of polyester and polyethylene in a film is usually described with numbers. For example, a "2-3" film consists of two mils of Polyester and three mils of polyethylene. The first number refers to the base layer. The second number refers to the adhesive layer. A mil is 1/1000 of a nch. Since polyester is the more costly of the two types of plastic generally used in laminating film, a "32" film will cost more than a "2-3" filn. Both are 5=mil fims, but the "3-2" version wil seem a little thicker on a piece of laminated material because it will be shightly stiffer. Thermal laminating films are available in many different base/adhesive combinations. Five mil film, for example, can be found in 1-4, 2~3, 3~2 and 4-1 combinations. In the US laminating trade, the generally accepted practice is to describe two-sided lamination, or encapsulation, by the thickness of one layer of film. For example, "3-mil lamination" should refer to lamination with two layers of 3-mil film. If you are buying or selling laminating film or lamination services, please make sure both parties understand the film descriptions being used.

There is a huge variety of themal laminating films available to suit many different kinds of

• -film with low-melt adhesives, also known as co-polymer films; these often have better clarity and are less likely to curl or ripple
• - matte films fo eliminate glare or to accept printing or writing; many suppliers offer films with both glossy and matte finishes
• - thermal film that has a pressure-sensitive adhesive and a release liner on its outer side; for example, a poster with this material laminated on the back could easily be mounted without fasteners or tape
• -""liner films" with a protective liner on the top cuter surface...after a piece of material has heen laminated, trimmed, packed and shipped, the person using the mnaferial can remove the protective liner, revealing a surface perfectly free of dust, scratches or abrasion
• - opaque or colored films for the back side of a lamination; these can form a border for a laminated piece
• - iridescent clear films for special visual effects
• - permanently waterproof flms for outdoor, underwaler or special applications: the most common thermal laminating films are made with water-based primers and will eventually de- laminate if continually exposed to water or weather; truly waterproof films are made with special

Rolls of film may be purchased in different widths. The size of the laminator is the only limitation to the width of the film rolls you can use. Make sure the upper and lower roll widths are the same, and are aligned with each other. When installing fiim, always center the rolls of fim on the supply roll mandrels so the core grippes cngage the cardboard core. Because it does not hold heat well, 1.5 mil film can be the most difficult gauge of film to use. A standard 1.5 mil film will run at about 310 degrees F, while a 3 mil film with the same adhesive type will run at 280 degrees F. Even when applied at 310 degrees F, the 1.5 mil film will not adhere as consistently as the 3 mil film applied at 280 degrees F , or a 5 mil applied at 250 degrees F. For many applications, 5 mil film does a much better job of protecting and enhancing items. Ten inil fim is suggested for those applications that need the most protection and rigidity. Seven mil films are also available. Rolls of film are scmetimes spliced. Most film suppliers will mark a splice with colored tape. This Way, you can see the splice as a "dash' of color on either end of the roll. If you spot a spliced roll in advance, you can put it on the top supply roll mandrel in order to see the splice

coming nore easily and avoid puting material under the splice. Or you could put it on the botton roll if you plan to be laminating items that will never be seen from the back side.

5-2 THREADING THE LAMINATOR

Chargement De La Machine

Cargamentodelamaouina

1. For safety, we suggest threading the laminator while it is cold. Remove the supply roll mandrels and feed tray. The supply roll mandrels are now ready to accept rolls of laminating fim, which is usually wound with the adhesive side "out" on rolls of flm with a core diameter of three inches.

Pour phus de securite, nous recommandons de charger la machine lorsqu'elle est froide. Enlever les mandrins ei le plaieau d'alimentation,puls insererla bobine defilm de plastique sur le mandrin.Les films de 3 pouces de diametre sont generalement enroules le cote adhesif a l'exterieur.

Para mayor seguridad,se recomienda cargar el plastificador cuando esta frio.Retire los rollos de a baste cimi en to y la bandeja de alimentaci6n, y ponga el rollo de pelicula de plastico,que por lo general esta enrollada con la parte adhesiva por fuera si se trata de una pelicula de pulgadas de diametro.

2. Position the rubber rollers in the open position. NOTE: The operator may have to recharge the air system by turning on the drive/compressor breaker and the main breaker.
3. Afier the air system is charged, make sure all of the breaker switches (1,2 & 3) and the main breaker (in back) are all off.
4. Tun slitter knife holders up, by pushing in the slitter activator #13. c NOTE: The slitting knives are EXTREMELY SHARP, and it is recommended that, while threading plastic through the pull rollers, or while working in the slitter assembly area, that the operator move the knife holders to the right and/or lef side of the machine to avoid possible contact with the knives. The slirting knives are located in front of the pull rollers. These can be adjusted by loosening the large kmurled knob on the rear of each blade holder and moving to the side.
5. Remove the feed table assembly by lifing it off the support bars. NOTE: The guard is designed to prevent accidental operator contact with the heated shoes or revolving rubber laminating rollers. If it is necessary to load the machine when the shoes are hot, EXERCISEEXTREMECAUTIONTOAVODTHE HEATSHOES,

Severe Burns Are Possible!!

6. Remove the top and bottom supply mandrels by lifting fiom the support slots.

7. Position the roll stop collars. It is necessary to evenly align both top and bottom plastic rolls to insure quality laminations and prevent "fouling" of the laminating and pu!! rollers with the polyethylene adhesive. If the webs are not properly aligned, the exposed edge of the adhesive will melt on the rollers, necessitating frequent cleaning. To insure proper alignment, your laminator is equipped with roll stop collars. Position the collar on the top mandrel to accommodate the width of plastic to be used. Lock in place by tightening screw.
8. Place the film on the supply roll mandrel as shown in the diagram on page 21. Place the loaded supply roll mandrel on the machine as shown in the picture. The polyester side (usually the shiny side) of the fim must go against the heat shoe. The polyethylene side (the dull side) of the film must face the operator. Remember that the shiny side (polyester side) of the film should always be against the heat shoes.
9. Slide a roll of fim onto the top supply roll mandrel. Center the roll. Put the loaded mandrel on the top brackets. Be sure both ends of the mandrel are filly seated in the brackets. Make sure the dull side of the film is facing up and the shiny side is facing the heat shoes during the threading
10. Refer to the appropriate threading diagram on page 21. With the top roll of fim centered on the mandrel and the shiny side facing down, thread the web of plastic under the top idler and then feed the web of plastic by hand over the top heaf shoe and through the laminating and pull rolls. MAKE SURE THE SHINY, OR POLYESTER SIDE, OF THE PLASTIC IS NEXT TO THE HEAT SHOE. I1. Measure distance from inside the top supply mandrel to the edge of plastic rol.

• loosen bottom roll stop collar.
• using measurement, position the bottom collar, lock in place and butt plastic against it.

12. Thread bottom roll of plastic in the same manner as the top roll of plastic was

must be removed to ease the threading process, but must be replaced prior to

• under the idler
• over the bottom heat shce
• thread through the rollers
• reinstall the removable idler

13. With both rolls threaded and installed in their respective brackets, unwind enough fim from the top roll to reach the bottom ofthe bottom heat shoe.Leave the top web in place.Next, unwind enough fim from the botton roll to reach the top of the top heat shoe. Use a bit of tape to hold the bottom web in place, overlapping the top web. If the machine is being threaded hot, ao tape is needed. The hot adhesive of the top web will hold the bottom web in place.
14. Put the feed tray/safety shield on the machine. Put the drive in forward and turn on the drive power. Put the speed control on a low speed. Close both sets of rollers. Turn both supply rols to produce about two inches of slack in both webs. Use a piece of heavy paper or cardboard to push the overlapped webs of flm into the laminating rollers. Once the web begins to go through the machine, make sure the leading edge goes over the slitter mounting bar and into the pull rollers. Turn the drive switch off, if necessary. Keep hands clear of the slitter blades and the pull rollers.

CAUTION:The laminator is designed to he run with the operator direcily facing the control pame and feed tray, mot at an angie or from fhe side ofthe machine.for cperator safety, the safety shield must be in position over the upper heat shoe when the machine is ON, or when the drive switch is in tae forward position.

15. Once the web has cleared the back of the machine, tum off the drive. If the machine was threaded cold, tun on the heaters now to proceed with setup. Adjust the set temperature and allow the machine to warm up.

S-3Supply Roll Tensionand Other

Ad Jiu Stm Ents

1. Now adjust the supply roll tension. First loosen all four supply roll tension knobs, then tighten them (turn clockwise) until they just begin to press on the springs. Another 1/4 to 2 tums (one tum equals 360 degree rotation of the kmob) of tension on all four knobs is usually sufficient for 1.5 or 3 mil film. More tension is required for 3mil. or heavier films. More tension is also required as the width of the film increases.

The best way to do the fine adjustment or readjustment of supply roll tension is to observe the film going over the shces while the drive is on. Tum on the drive. Both laminating and puil rollers must be closed and locked. Adjust the speed to match the expected lamination work.

If the supply roll tension is too loose, some wrinkles can be observed at the leading edges of both shoes. Lines of air may also be observed between the filn and the shoes at the leading edges.The visual effect caused by air between the film and the shoes is known as "waterfalling."

If some wrinkles and/or a water falling effect extend about 1/3 of the way across both shoes from the leading edges toward the trailing edges, the supply roll tension is close to perfecl' for most jobs. (The leading edge of the top shoe is the top edge. The leading edge of the bottom shoe is the bottom edge. The trailing edges of both shoes lead into the "nip," where the two laminating rollers come together.)

If the film is going over both shoes without any wrinkling or water falling, supply roll tension is too high. If the wrinkling is extending into the nip, supply roll tension is to0 low. Supply roll tension is not an absolute adjustment. The acceptable range of tension settings is fainly wide. If little wrinkling or water falling is visible on the leading edges, tension could be reduced a little. If the wrinkling or water falling is extending to the trailing edges, tension could be increased a litle. Make sure that top and bottom rollers have about the same tension.

2. What we,call the "drape test" is an effective way to evaluate supply roll tension simply by examining the laminate.Rum about two feet of film out the back of the machine. Cut the web of film at the exit point. Hold the two corners of the film on the side where it was cut away from the laminator, with the bottom side facing you. Let it drape straight down. If the film hangs perfectly straight and flat, or if there's a small amount of cul in one of the bottom comers, the supply roll tension is set about right.

If the bottom edge is curling toward you, there is too much tension on the bottom roller. If the bottom edge is curling away from you, there is too much tension on the top roller. If the two bottom comers are curling in opposite directions, supply roll tension is to0 high on both top and boftom. Both novice and experienced operators oflaminators tend to use too much supply roll tension. The best amount of supply roll tension is the least amount that will do the job.

3. Stop the machine for approx in at ely fifteen seconds to allow the laminating rollers to line" to pass through the pull rollers, so that it can be observed. The "dwell line" should be approximately 3/8"wide at each edge of the web of plastic and possibly a little narrower in the center. It should look similar to this:

like this:

Apply additional pressure as required. Repeat the above test to see if the rolls are balanced properly.

5-4LAMNATING

1. Tum on the power and the heaters.

• Set the temperature. The small green output light will come on while the machine is wamming up, approximately twenty minutes. When the two heat indicators are at the desired temperature the machine is Teady to laminate.
• - Open both sets of rollers. Put the drive direction switch in forward and tum on the drive.This allows the laminating rollers to tum and get evenly heated while the machine is waming up. Evenly heated rollers contribute to the quality of the lamination. WARNING:Never permit the temperature to excced 310 degrees Fahrenheit while flm is threaded and the laminator is mot ruaning. The film could disintegrate and require cleaning and rethreading of the machine. When it is necessary to laminate at temperatures in excess of 310 dcgrees -- such as for poster board - pull some excess flm eff the filu supply rolls to provide slack so the film is not tight against the heat shoes while the machine is heating. This will keer the filn from melting when the lamimator is not aavancing fim. MISE EN GARGE: Ne jamuis laisser la tenperature depasser 31oF lorsque lefilm est chargeet gue la muchine n'est pas utilsee, car le film risgue de fondre, auguel cas il faudrait nettoyer la muchine el proceder a nouveau au chargement du film.

2. During warmup, the actual temperature will sometimes overshoot the set temperature by more than a few degrees. Then when lamination is begun, the achual temperature may iniially drop below the set temperature. Unless these temperature Swings are extreme there is no cause for concerm.

The heat controllers each contain an intelligent processor which gauges the heat requirements of any job being run on the laminator. The processor adjusts the power to the heat shoes to keep the actual temperature steady and close to the set temperature:

This process of gauging and adjusting the heat takes a few minutes, so the achual temperature will become more stable as you continue to laminate.

3. Add or remove feed tray sections and position the two side sections for the work to be
4. Check the supply roll tension per the instructions in the previous section. Make sure the top and bottom supply rolls have about the same tension.
5. Once the machine has come up to temperature you are ready to laminate. Close the pull rollers first, then close the laminating rollers. Adjust the film speed as required. Once the film starts to move, watch it as it passes over the heat shoes. Allow any wrinkling to clear out before inserting material to be laminated. Each time you stop the advance offilm, whether by opening the rollers or tuming off the drive, slack will form in the web of film. It will take a few inches of fim to get the slack and the resulting wrinkles past the shoes.
6. Examine the film as it exits the machine. If there are bubbles or wrinkles in the fiim. it could mean there is not enough tension to draw the film tight and smooth over the heat shoes. It could also indicate that the rollers are not closed.
7. As mentioned earlier in this operators' guide, many users tend to use too much supply Ioll tension. Some film such as I.5 mil, requires very litle tension. Here are some indicators that you might have excessive supply roll tension. usually loud squcaling (many films will squeal a little) necking (the web of flm gets narower as it goes across the shoe) no water falling or wrinkling anywhere on the shoe.. the film is perfectly smooth and tight across the surfaces of both shoes (please see the previous section on adjusting supply roll tension). If the filn curls up as it leaves the machine, loosen the top suppiy roll mandrel (tum cou mter clockwise) and/or tighten the bottom supply roll mandrel (turn clock wise). Ifthe film curls dowm after it leaves the machine, tighten the top supply roll mandrel (turn clockwise) and/or loosen the bottom supply roll mandrel (tun counter-clockwise). In making these adjustments, make sure that top and botton supply roll tension are kept about equal.
8. When running films of 3 mil or above, tum the fans on before beginning to laminate. "Waves"'or "'ripples" tending to run through the center of the laminated web are usually caused by forgeting to nun the fans, or seting too high a temperature for the fim being

"Heat wrinkles" are formed when the film as not cooled enough before coming out the back of the machine. For the best results, the film should be cooled helow melt

temperature while it is pulled tight and perfectly flar between the laminating rollers and the pull rollers. If it gets out the back of the machine while still at or above melt temperature, heat wrinkles can form. The major reason for fans on a laminator is to cool the laminate, not to cool the machine.

9. This machine is equipped with a directional switch: forward/neutral/reverse. Tum to the forward position to laminate, or to reverse as required. The manufacturer recommends the stop switch be used to stop the laminator rather than the neutral position of the directional switch. To remove anything which may become lodged between the rubber laminating or pull rollers, remove the feed tray assembly, and open rollers. Switch control to reverse if required.
10. A. unique feature of the laminator is the provision for driving both top and bottom pull rollers and laminating rollers. This feature provides an even distribution of heat on a continuous basis to the laminating rollers prior to startup, or when laminating production is temporarily halted.

Tokeepthelaminatingrollershotwhenlamnatoris

Not In Production:

• Open the laminating rollers then open pull rollers.
• - Turn off cooling fan.
• - Tum directional switch to forward.
• - Tun motor drive switch to on. Turn the variable speed control to the minimum position. The laminating rollers will revolve in proximity to the heat shoes when these steps are followed. This eliminates the chance for imperfections in the finished lamination caused "cold spots" on the laminating rollers.
• - The laminator becomes capable of accepting thick materials, without rol! slippage because the top and bottom rollers are driven. Driven rollers also minimize the "curling effect" in the finished lamination by providing balanced power to the laminating and pull rollers.

11. The laminator is designed to operate with the operator directly facing the control panels and feed tray assembly.

• For operator safety, the feed table/heat shoe guard, an integral componen of the feed tahle assembly, MUST BE IN ITS DESIGNATED POSITION when the temperature of the heat shoes is in excess of normal room temperature, or when the drive switch is in the forward position.

5-5 RECOMMENDED TEMPERATURE SETTINGS

The laminator is usually set at 300 degrees Fahrenheit at the factory. This is the best temperature setting for the particular 1.5 or 3 mil film used during testing. Many users will be changing the temperature to 310 F for a standard 1.5 mil film, or to 280 F for a standard 3 mil film.

Your first source of information about recommended film application temperatures and operating characteristics should be your film suppliers. If you do not know the source of your film, or if the supplier cannot provide the information, please use the following table as a guide.

Film Thickness Temperature Setting Fan Position

1.5 mil 300 to 315degree range .0015 inch OPTIONAL .003 inch 3 mil 275 to 300degree range ON .005 inch 275 to 300 degree range ON 260 to 275 degree range .005 inch ON

.0015 inch 310 to 340 degree range OPTIONAL (on thick paper)

3 or 5 mil 200 to 260 degree range ON see above

NOTE: It is possible that variances from recommended temperature settings may be necessary due to material thickness, ambient temperature, humidity or quality of laminating material.

S-6 Slitter Operation

1. The slitters on the HD-38/50/60 can be moved independently from the sides of the machine, even while lamination is in progress. The slitter heads are mounted on a stee! bar with a adjusting knob on each knife holder. The sliters must be positioned manually. Additional slitters may be ordered.
2. To engage the slitters, pull out the sliter knob (#13) on the control panel (right side), while the film is being slowly advanced. I may be necessary to pull the fim up for the blades to break through the film.

Do not do this with your fingers! Use an implement such as a rule or a screwdriver. always take care to keep hands clear of the slitter blades when threading flm or Otherwise working around that section of the lamimator.

3. When using the sliter, items being laminated must be fed into the machine squarely, OI the slit edges will not be parallel with the edges of the items. The cdge seal or edge trim will be uneven if the leading edge of cach item is not fed at right angles to the edges of the web of film.

S7Preventing And Solving Problems

Please read this section before you have a problem

PROBLEM: Wrinkling of the material as it goes into the laminating rollers. This problem usually occurs when laminating an item that has been folded, rolled, bent or

SOLUTION: Make sure the leading edgc of the item being laminated is laying flat and is inserted paralle! to the laminating rollers

It is sometimes essential to smooth out an item as it passes over the feed table and through the rollers to ensure an even lamination without wrinkles. Smooth from the center of the item, back toward the trailing edges. Once the item starts to feed, you may also pull back and to the sides on the comers of the trailing edge.

If material has been rolled up, take the curl out of it cn a table edge beforc laminating. If some curl remains, it may be helpful to insert the item with the curl down se the leading edge is pressed against the feed tray until just before the nip.

PROBLEM: Wrinkling of the film aroumd the material being laminated.

SOLUTIoN: This is nomal and inevitable on any laminator, especially with thicker material. These wrinkles will be trimmed away with the scrap, so they do not affect appcarance. Because the rollers are being held apart by the paper or cardboard, they cannot pull equally oh the plastic around the paper. This creaies wrinkles that fend to look like the bow waves of a boat, radiating out through the clear part of the web from the sheet of material.

PROBLEM: When two pieces of material are laminated side by side, the plastic adheres to one piece but not the other.

SOLUTION: To get maximum efficiency from the film rolls, you can feed several items into the laminator side by side. However, wrinkling can occur if these items are of unequal thickness, because the laminating rollers are lifted off the thinner items by the thicker items. When laminating items side by side, it is important to arrange them so that the thickness is the same.

PROBLEM: Wrinkling of the plastic on a laminated piece of material. SOLUTIONS: Make sure you have enough supply roll tension to take the wrinkles out of the film before it gets past the heat shoes. (see supply roll tension, section 5-4) Make sure the film is threaded properly (see threading the laminator, section 5-2). The most frequent operator enror is threading the film under the bottom stabilizer bar instead

of under the bottom idler bar.The threaded fim should nor touch the bottom stabilizer bar.When the bottom web of film is threaded around the stabilizer bar instead of the idler bar, the film will tend to wrinkle and often will not adhere.The top side of the item will not be affected. PROBLEM: Wrinkling occurs in the film over the laminated item, and the rolls of fim move from side to side on the supply roll mandrels. SOLUTIONS: Check the supply roll mandreis. You'll probably find the mandrels are reversed. Take the rolls of film off and reverse the mandrel or mandrels which are backwards. (see supply roll mandrel diagrams) When the supply roll mandrels are 1eversed the core grippers (we sometimes call them "dogs') point in the wrong direction to hold the rolls of film. Because the cardboard cores are tuming on the mandrels, there is no supply roll tension control and the rolls of film are able to slide from side to side on the mandrel

PROBLEM: Film gets wrapped around the pull rollers. SOLUTON: While threading the fim cold, the loose ends of the unlaminated web are particularly susceptible to "wrap-around". To minimize this, pull the threading card after it emerges from the pull rollers until the flm clears the exit table. Then cut off the excess film flush with the pullrollers prior to laminating. Use caution when first starting to laminate, being careful that the thin, unlaminated web does not get caught in pull rollers or laminating rollers. If "wrap-around" does occur while the laminator is cold, you can easily correct it by reversing the direction of the rubber rolls, permitting the laminator to release the film from the rolls.

PROBLEM: Film gets wrapped around the laminating rollers while the machine is hot. SOL UTION: Leaving the heat on so that the adhesive does not harden, follow the following steps.

1. Remove the feed tray.
2. Cut the film on the top and bottom, just in front of the idler bars.

3. Loosen the film from the heat shoes and grip the two loose ends, hoiding them
4. Tun the drive switch to the reverse position.
5. Tum on the drive at a very low speed and allow the laminator to back out the flm that is wrapped around the rolls. Pul the fim off the roller. WARNING: Keeping the machine in reverse may cause a reverse wrap-around if the fm is not getting pulled off the roller. You may need to pall on the flm with a lot of force whie stopping and starting the drive.

If this method does not work, let the machine fully cool. Remove the heat shoes and cut the wrap-around off the roller with a small pair of scissors, working the point and the cutting edges away from the rubber to avoid damaging the roller. Then clean the rollers per the instructions in section 6-3.

PROBLEM: Not noticing that the rolls of film are almost used up (one roll of fim always runs out before the other.)

WARNING: If the film is run through the laminator without being matched to an Opposing film, the adhesive exposed to the rubber rollers wil stick to the luminating rollers and create a world-class wraparound. This type of wraparound is diffcult to clear because the film adheres to the roler and to itself for the entire length of the

accumulated fiim on the roller.It's best to clear this right away,before the adhesive hardens. Follow the steps ahove to clear.

SOLUTlON: To avoid this problem, stop the laminator before either roll runs out, cut the webs of film. and remove the two near-empty rolls of film and then rethread new rolls. When putting fim on a laminator, always use two rolls of matched length and

Experienced users may leave the pieces of film remaining over the shoes and in the rollers to help thread the new film. When the machine is wam, the ends of the new rolls can be easily tacked to the already threaded pieces because the adhesive layer facing oufwards will be sticky. Be carefu! not to bum yourself on the heat shoes. PROBLEM: Film is not properly adhered or starts to come off sometime after

SOLUTION: Unless there is something wrong with the film, this problem comes from film being run at too low a temperature. Check the heat setting on the laminator. (see recommended temperature settings, section 5-5). If the film is not sticking to the item, it is likely that more heat is required. If you are using 1.S mil film, this problem can occur if you are running the machine too slowly. Because 1.5 mil film is thin and therefore loses heat easily, it can cool off too much between the heat shoes and the roller nip if it is run too slowly. If you are running thicker films, you may have the problem if you try to go too fast. In this case, the thicker film may not have enough time on the heat shoes to reach its adhesive melt temperature. Thicker films may be run at low speeds with no problem. When laminating posters or other thicker material with 1.5 mil film, the paper itself can absorb enough of the heat from the film to drop the adhesive below its melt temperature.

The fim may start to come off immediately or it may start to fall off after a few days. The solution here is to nun the work at a higher temperature. About 320 to 340 degrees F will usually do the job. Sometimes you may see filim detach from an item along one edge (the edge that was put in first). This happens when the material is put all the way into the nip before the machine is started. The area of film between the shoes and the nip can cool off too much while the machine is idle. The adhesive may not be hot enough to stick. The way to prevent this is to let a few inches of film go though before putting in sheets to be laminated. This serves other purposes, besides ensuring the front edge of the piece will be properly sealed. H gives the machine a chance to take up the slack that develops in the fim whenever the machine is stopped, and it prevents the following problem as

SOLUTION: It's not oil that causes this effect, but excess adhesive. When a machine is left heated but idle for a few minutes or longer, the adhesive from the film over the shoes can form droplets if material is put in immediately. This excess adhesive saturates an area of paper, creating what looks like an oily spot. The solution, as mentioned above, is just to let a few inches of film go through before feeding in your work. Anytime you are laminating unfamiliar or costly items, it is a good idea to start with an expendable sample or test piece. Laminating a test piece first gives you an indication of The results you'll get and also takes care of any pooled adhesive. PROBLEM: A milky, hazy line aboul an inch wide appears periodically across the width of the web immediately after initial warm-up. (LAMNATING, section 5-5, steps

SOLUTION: The rollers are not evenly heated, and the cold side of the rollers is preventing the adhesive from melting. When waming up the machine, keep the rollers open and keep the forward drive on at low speed. PROBLEM: The machine produces a coninuous squealing noise when laminating SOLUTION: To a certain extent, it is normal for some laminating film to squeal as it is pulled over the heat shoes under tension. This noise is produced via the same principles that make a violin squeal. Some of the compounds put on film to keep it from sticking to iiself seem to act like resin on the bow of the violin -- they enhance the noise. To minimize squealing, run the laminator with the least amount of supply roll tension that will do the job of removing wrinkles from the web of film. Make sure you are not

using a higher temperature than needed and clean the heat shoes periodically (see section 6-2). If the noise gets really objectionable, use a different iype or different brand of film PROBLEM: The laminated material seems to have a pitted surface or irregular surface that does not match the texture of the paper being coated.

SOLUTION: This is usually caused by adhesive build-up or dirt on the rubber rollers, but may be caused by any matter stuck to the rollers, such as a piece of paper. Inspect the rubber rollers and if they need cleaning refer to section 6-3.

Irregularities in the surface of the film can also be caused by cuts or other damage to the nubber rollers, especially the laminating rollers. On a HD 38/50/60 the pull rollers are identical to the laminating rollers and could be substituted if still in good condition.

PROBLEM: The film shrinks as it passed over the heat shoe (known as "necking: in the laminating trade). SOLUTION: Reduce the heat and/or the supply roll tension. The film is not shrinking so much as it is being stretched by excess heat and tension, causing the web to get narrower as it is pulled over the shoes.

PROBLEM: No power is getting to the laminator.

SOLUTIoN: Make sure there is power at the electrical outlet being used, and make sure both ends of the power cord are fimly engaged. There are fuses inside the laminator, but dead outlets and loose power cord connections are the most commcn causes of this

PROBLEM: Wavy or rippled sections in the laminate, especially toward the center of the web.

SOLUTION: Increase the temperature. That cloudiness is a function of incomplete adhesion. On a variable speed machine loaded with thicker film, it may be that the fim is being run too fast and is not getting enough time on the heat shoes. PROBLEM: Bubbles in the center of the web and/or film not sticking to the center of an item.

SOLUTION: This problem can be caused by excessive laminating roll pressure. Putting too much pressure on the laminating rollers actually decreases pressure in the center of the web. The other likely cause of this symptom is worn rollers. For example, if hundreds of thousands of 18-inch wide sheets are laminated on a 38-inch machine, the center of the follers can get wom down more than the ends of the rollers. In this situation, the

laminating rollers should be replaced. The rollers wor in this way are not suitable for use as pull rollers.

6-2 GENERAL CLEANING

Cleaning the laminator daily or weekly will help prevent dirt or adhesive build-up on the rubber rollers and heat shces and will improve the performance of the unit.

6-3 CLEANNG THE HEAT SHOES

During nomal use, excess adhesive from the fin will often cling to the heat shoes, especially near the edges. Film coating powders can also build up on the shoes, and will tend to increase friction between the film and the shoes. This type of build-up may not be visible, and it may adversely affect lamination in a number of ways. Film squealing loudly as it passes over the shoe can sometimes be a symptom of this problem. Some films naturally tend to squeal, with or without coating powder build-up, but cleaning the shoes usually helps reduce squealing and helps prevent more serious

To clean the shoes, heat the machine to full laminating temperature to soffen the adhesive. Put on oven mitts or heavy gloves to protect your hands. Using a clean, soft, dry cloth, gently rub the adhesive or other contaminants off the shoes. Never usc any abrasive material or rub too hard on the shoes, because you may remove the Teflon

You may dampen your cleaning cloth with soapy water or a mild water-based cleaning solution, but make sure you carefully insulate your hands from possible steam bums if you do this. The steam fomed when water hits the hot surface can penetrate both the cleaning cloth and your gloves.

6-4 CLEANINGTHE RUBBER ROLLERS

Both the laminating rollers and the pull rollers need regular cleaning. Collectively these are referred to as the nubber rollers.

To clean the laminating rollers, tum off the master power switch and unplug the machine. Remove the heat shoes. The upper shoe can be simply lifted off its mounting bolts and the wiring disconnected. The bottom shoe is easily removed by taking out the mounting boits. Clean the rubber rollers with a mildly abrasive cleaning pad such as a white Scotch Brite pad which may be purchased in the household section of your grocery store (the green pads are too abrasive). Use mildly soapy water to clean the rollers. Rub firmly but do not scnub the rollers vigorously as this might mar the surface. Do not use sharp metal objects or steel wool as these will also mar the rollers.
