4.6 Feed Table Assembly Installation

Insert the feed table with the feed wheel toward the fold rolls. Slide the paper feed table over both sets of locating pins. (See Figure 4.6-1)

The first notch in the front part of the feed table should rest on the pins. Then drop the rear notch down on the upper dowel pins.

Rotate the handwheel to check that the gears are properly meshed.

Connect the feed table hoses. Push the fittings into the holes in the manifold block. (See Figure 4.6-2)

5.0 ELECTRICAL ACCESS

4.7 Fold Plate Installation

WARNING

Unplug the AC power cord before attempting any electrical repair.

WARNING

Unplug the AC power cord when installing or removing fold plates.

The motor speed control and counter control are located under the left-hand side cover. The handwheel must be removed for access to these controls.

The fold plates are marked #1 and #2 and are not interchangeable. The #1 fold plate is installed in the top position, the #2 fold plate in the lower position.

Each fold plate has an open end which faces toward the fold rolls.

To install the fold plates, pivot the fold plate holddowns out of the way and slide the fold plate in position so that the slots in the leading edge of the fold plate engage the two locating pins in the side frames. (See Figure 4.7-1)

The cover can be removed by taking out the four screws located on the inside of the frame.

6.0 SETUP

6.1 Setting The Controls

The operator controls are conveniently located on a control panel on the left-hand side of the 714XLT.

The center notches should seat on the second set of locating pins. Pivot the fold plate hold-downs back into position to secure the fold plates.

Turn the handwheel to be sure that the fold plates are properly installed and not rubbing on the fold rolls.

These controls consist of an On/Off power switch, which is an overload reset, a speed control potentiometer, a pump On/Off switch, and a counter with zero reset.

Set these initially at:

1. Power Switch
2. Speed Control
3. Pump Switch
4. Counter

Off position “0” position Off position “0” position

6.2 Determining Paper Size and Type of Fold

The next step is to determine the paper size and type of fold to be made, following the steps below:

1. Measure a sample sheet of the job to be run to determine its size. Retain this information for later use.
2. Refer to the printed chart on the stacker tray (See Figure 6.2-1) and locate the type of fold that you want to make. (Example: letter fold)
3. Locate on the chart the columns corresponding to the sheet size measured in Step A. (Example: 8 1/ 2x11)

Holddown

4. Locate the point on the chart where the columns for the type of fold and the sheet size intersect. You will notice that there are either two letters or a dash and a letter. These letters and/or dash tell you where to set the paper stop on the fold plate, and whether or not one of the fold plates will be installed in the deflector position.

Example #1 ; To make a letter fold to an 8 1/2 x11 sheet, set the paper stops for the #1 and #2 fold plates on the letter E. No dash appears, so neither fold plate is installed in the deflector position.

Example #2: To make a single fold to an 8 1/2x11 sheet, install the #2 fold plate in the deflector position. Set the paper stop for the #1 fold plate at the letter K.

6.3 Paper Stop Adjustment

To move the paper stops to the correct position as determined in step #2, depress the coarse adjustment knobs on the paper stop and slide the paper stop until the indicating edge is aligned with the proper letter on the fold plate. (See Figure 6.3-1)

With the machine running, insert two sheets of paper between the tab and the sucker wheel. Turn the gap knob counterclockwise until there is a slight drag on the paper. Remove the paper. The correct gap is now set. (See Figure 6.4-1)

To obtain an exact setting on the paper stops, turn the micro-adjustment knobs until the indicating edge of the paper stop is perfectly aligned with the line adjacent to the letter on the plate.

6.5 Feed Table Adjustment

6.6 Air Blow Adjustment

On the paper feed table there are two guides which keep the stack of paper properly aligned for feeding into the folder. Adjust these guides to correspond with the different widths of paper being fed. (See Figure 6.5-1)

Turn the air blow adjustment on the vacuum/aircontrol panel fully counterclockwise to the + position. Except for when very small sheets are being run, the air blow adjustment is left adjusted for maximum air. (See Figure 6.6-1)

To adjust the paper feed guides, loosen the two side guide locking knobs on each guide. Slide the guides from side to side until the inside edge of each guide is aligned with the number corresponding to the width of the paper being folded.

Once the amount of air blow has been selected using the air blow adjustment, the feeder valve knob may be used to direct the air (See Figure 6.5-1).

Turn the knob to the right to obtain more blow on the right side and front of the feed table. Turn the knob to the left to obtain more blow on the left side and lessen the front blow.

Example: For an 8 1/2-in wide sheet, move the side guides until the inside edges align with the “8 1/2” on the feed table.

An additional check is to lay a sheet of paper on the feeder, close to but not touching the side guides. Push the sheet down into the nip of the fold rolls. Then align the guide by loosening the adjusting knobs and aligning the guide so that it is parallel to the edge of the paper. When one side is square, the other side can be moved into position.

Tighten the locking knobs to secure the paper guides in position.

Turn the vacuum adjustment clockwise all the way down. This setting is used for most light and medium papers. Heavy paper will require more vacuum.

When you load the actual job, you may have to move these guides slightly to take care of variations in sheet size. To feed properly, the paper must slide freely between these guides.

7.0 OPERATION

Side Guide Locking Knobs

Feeder Valve Knob (not shown)

7.1 Loading of Feed Table

Before you can load the paper on the feed table, you must determine which way the paper is to be loaded by running a few sample sheets. (Example: printing face up or face down)

Then you can load a stack of paper no higher than two inches between the paper feed guides. Let the stack slide freely down into position between the side guides.

7.2 Starting the Vacuum/Air Feeder

Side Guide Adjustment Knobs

After the vacuum and air adjustments have been made, start the folder, then start the vacuum/pump.

TOP SHAFT

Additional paper can be loaded on top of the stack of paper already in the feeder without stopping the machine.

If the feeder runs out of paper or if you want to stop the machine for any reason, first turn off the vacuum pump, then the folder.

7.3 Check Squareness of Fold

Examine the folded sheets on the stacker to make sure that you are getting an even and square fold.

Figure 8.1-1 The perforating blade holder assembly is then slid onto the upper slitter shaft along with the necessary pullout tire assemblies. Then tighten the screws holding the perforator blade to the blade holder, aligning the blade to the holder. This allows for free horizontal movement on the shaft.

There is a skew adjustment on each plate to adjust for a square fold on paper that is not cut square (See figure 4.7-1).

7.4 Use of Handwheel

The handwheel is used to help clear jams and for setup. To use the handwheel, shut off the folder, pull out the handwheel and turn it in either direction.

Slide the grooved perforator collar onto the lower slitter shaft along with the other pull-out tire assemblies. The flat side of the perforator blade should just touch the side of the groove in the perforator collar. (See Figure 8.1-1)

8.0 PERFORATING, SCORING & SLITTING

TOP SHAFT

In addition to folding, your 714XLT Air Feed can perforate, score and slit.

WARNING

Be careful when handling perforator and slitting blades. They are extremely sharp.

The 714XLT can be used to perforate either the folded sheet (to assist in making a right-angle fold) or to perforate sheets delivered flat. BAUMFOLDER supplies one standard 41-tooth perforator blade. Additional perforator blades are available through the BAUMFOLDER Parts Department.

The perforator blade should be mounted loosely to the blade holder with the retainer collar to give better support to the perforator blade. Always be sure that the flat side of the blade is against the blade holder. Loosen the brass-tipped set screws in the perforator collar and blade holder before attempting to place them on the slitter shafts.

Slide the perforator collar and blade holder to the desired position on the slitter shaft. Then lock the blade holder and perforator collar into position with the brasstipped set screw.

The perforator stripper fits onto the slitter shaft bar in between or next to the perforating blade. (See Figure 8.1-2) This strips the paper off for delivery and prevents it from wrapping around the perforator blade.

TOP SHAFT

The 714XLT can be used to score a sheet and deliver it flat, or to score a sheet after a fold or folds have been made.

To ensure accuracy in making right-angle folds, always score the sheet where the fold is to be made. This applies in all instances when a perforator cannot be used.

Attach the scoring blade loosely to the blade holder for mounting on the slitter shaft. Scoring blades can be mounted on either the upper or lower slitter shaft. Once on the shaft, tighten the screws, aligning both the blade and the collar. This allows free horizontal movement on the shaft. Scoring blades should be placed so that the fold will be made with rather than against the scoring, or, in a continuing direction to the pressure of the crease that has been applied by the scoring blade.

NOTE: Slitting accessories are optional on your 714XLT and can be ordered from your BAUMFOLDER Parts Department.

The 714XLT can be used to cut folded or flat sheets apart. The general setup for blades and collars is shown in (Figure 8.3.1). Two or more cuts may be made if duplicate sets of cutters are used.

TOP SHAFT

TOP SHAFT

Use care in mounting slitter blades to the collars in order to avoid ragged edges during slitting operations. Ragged edges can be caused by two conditions:

For a wide, well-rounded score, use the two steel scoring collars. (See Figure 8.2-1) Sharpness and the depth of the score can be controlled by regulating the distance the collars are placed away from the scoring blade.

The scoring collars can also be placed on either side of the rubber scoring collar. The two collars can be compressed against the rubber collar, causing the rubber to bulge up for a deeper score. (See Figure 8.2-2)

1. Nicks or burrs on the collars or blades. Remove carefully by filing or using a fine piece of emery cloth.
2. Incorrect mounting of blades caused by tightening with the wrong type of screw. Always use flat head screws on the side of the blade and blade holder collar, which are countersunk.

Before tightening the blade to the collar, slide the blade with the collar loosely attached on the end of the shaft. Then tighten securely, thus aligning both the blade and collar, allowing free horizontal movement along the shaft.

9.6 Cleaning The Fold Stop Guides

Place the blade, mounted on the collar, on the upper shaft in the proper position where the cut is to be made. Then move the blade and collar on the lower shaft so that the two flat edges of the blades are pressed snugly together. Too much space between the blades will produce a ragged cut.

Space the rubber pull-out tires to support the sheet.

The fold stop guides (See figure 4.7-1) should be cleaned once a week with a dry cloth to keep the plate moving properly.

9.0 MAINTENANCE

9.1 Maintenance and Care of your 714XLT

The 714XLT Air Feed has been designed to give you years of useful service, provided you maintain it according to these instructions.

Apply one or two drops of light machine oil at all slitter shaft bearings and the feed table bearings and idler gear once a week. Be sure to keep oil off any surface which may contact the paper.

9.3 Cleaning of Fold Rolls

Periodically wipe off the rubber surface of the fold rolls using an approved solvent such as Surewash or its equivalent. Surewash is available from BAUMFOLDER in 1-quart (P/N 24108-001) and 1-gallon (P/N 24108-002) containers. A complementary bottle of Surewash is included with your machine.

The filters on the pump should be checked periodically and cleaned as needed. The filters can be reached by unscrewing the filter jars.
