ATTENTION : DO NOT PUT HANDS CLOSE TO GLUE TANK

4.5 Adjustment of the Machine/Components

Function The purpose of notching is to enhance the solidification of the bookbinding. The notching blade makes numerous cuts on the spine of the book so that the melted glue can penetrate the binding area.

In order to get appropriate depth of the cuts and the precision of the center path for clamp station, the notching

station can be adjusted to the up, down, right, and left positions as shown. Note that notching surface should be

adjusted evenly on both sides to prevent tilting the notching surface. Otherwise, the cuts of the book will have one

side deeper than the other. The standard depths of the cuts are 1 mm evenly on the spine of the book.

You also can lift up the notching station to gain the depth of the cuts when the blade has been worn out a little bit. Or you have to change the blade.

1. Open one side of the notching station
2. Loosen the blade screw and remove the old blade
3. Install the new blade as shown, then set the height of the blade about 3mm above the surface of notching wheel
4. Tighten the blade screw

Providing a layer of melted glue on the spine of the book so that cover and pages can be bound together .

The glue scraper of glue tank controls the quantity of the melted glue on the glue drum while the glue meter controls the thickness of melted glue that is applied to the spine

• Adjusting the gap for the glue meter:

1.) Set the glue-adjusting knob to the left ( MIN ) position

2.) Use a ruler from the surface of the nipping station across the glue tank as shown on the following page. The ruler should touch the glue meter. Then measure the distance between the ruler and the peak of glue drum.

Note that the standard gap between the ruler and the peak of glue drum is 2 to 3 mm.

• Adjusting the gap for the glue scraper:

1.) Loosen the two screws on the glue scraper.

2.) Measure the distance between glue scraper and the glue drum as shown. Note that the standard

gap between glue scraper and the glue drum is 2 mm.

3.) Tighten the screws.

• Setting the glue -adjusting knob to the appropriate positions:

Normally, the indicator is set at 1/3 to 1/2 of the arrow mark.

• Controlling the quality of a book by means of the glue meter: Note that the thickness of the cover

sheet is an important factor for you to make a good spine. Use only the appropriate thic kness of

cover sheet to make a good book.

1.) Decrease the melted glue when:

2.) Increase the melted glue when:

Provided a flat surface for the book block, when there are being placed into the clamp station. It also

provides the nipping force to form the cover around the spine of the book

1.) During the nipping process, the nipping plates must exert an even pressure on the cover in order to form

2.) The nipping swing arms provide this pressure

Open the nipping station, then turn the swing arms counter-clockwise to the position shown. The swing arms

must touch together at the centerline as shown.

If not, they need to be adjusted.

• Position change on the position disc of nipping station

There are three positions of the nipping station for executing the clamping, the cover, and the nipping processes. The LED of the sensor (LS3 or LS4) goes on when the notch of position disc travels through the trench of the sensor as shown below:

1.) Clamping: when the bearing is at the highest point

2.) Cover: when the bearing is at the lowest point

3.) Nipping: when the bearing is at the sub-high point

If the spine is not being nipped evenly, adjust the nipping plates as follows:

• Adjusting on the Nipping Plates

1.) Push each side of nipping plates to find out which side is too tight.

2.) Then use the nipping plate screws to do the fine adjustment until both sides have the same tension.

Note that you can use the“MOTOR2” of “TEST2” to verify the nipping plate position before tightening them.

Nipping plate adjustment screws

• Position Adjustments on Nipping Station

1. The level of nipping station should be adjusted evenly on the corresponding ends to prevent tilting the nipping station surface, by level adjusting screws. (B) The centerline of the nipping station must match the projected centerline of the clamp station by the front/rear adjusting screws. (C) The position of cover can be

adjusted by the cover position adjusting screws, along with the position of LS1.

TAPE MODE BLOCKS Adjustment / Cover Position Fixed ruler

TAPE mode using tape instead of cover blocks adjusting was as the cover center adjusting. Please install blocks first before your adjustment. Cover position fixed ruler can be pulled out to fix your covers position. Fixed device can fix the ruler firmly in the place you want.

Holding the book block for the notching, gluing, and nipping processes of bookbinding.

The acceptable spine of a book and the shape of book block after being clamped are shown below. If you find different shapes such as “round”, “hollow” and “nail head” for one end or both ends, remove the clamp covers, then adjust the screws on both clamps.

1.) Making book is a top priority (to see where is the machine need to be adjusted ):

The priority way of machine’s measurement is making books. We usually make 5mm, 10mm, 15mm, 20mm as well as 30mmof thickness to inspect. however, 20mm is a standard for us to make sure the spine of the book should be good. Because nail head usually happen in thicker books, and round spine usually happen in thinner books.

2.) How to adjust the angle/pressure of the clamp plate If you need to adjust the clamp plate, please refer to following points:

LL and LR corners are nail head: it means that the left spine of the book should be lift up to make the left side of the spine rounder. So you can increase adjustment on both NON-OP Plate1 and OP Plate 1，and

making book to see LL and LR corners are ok or not.

LL corner is nail head: it means that the LL corner should be lift up to make the LL corner rounder, So you can increase adjustment on NON-OP Plate 1，, and then making book to see LL corner is ok or not.

LR corner is nail head: it means that the LR corner should be lift up to make the LR corner rounder, So you can increase adjustment on OP Plate 1， making book to see LR corner is ok or not.

RL and RR corners are nail head: it means that the right spine of the book should be lift up to make the right side of the spine rounder. So you can increase adjustment on both NON-OP Plate 3 and OP Plate 3，,

and then making book to see RL and RR corners are ok or not.

RL corner is nail head: it means that the RL corner should be lift up to make the RL corner rounder, So you can increase adjustment on NON-OP Plate 3， and then making book to see RL corner is ok or not.

RR corner is nail head: it means that the RR corner should be lift up to make the RR corner rounder, So you can increase adjustment on OP Plate 3， and then making book to see RR corner is ok or not.

All above are nail head situation, if round spine or corner happened, please refer to following point:

LL and LR corners are round: it means that the left spine of the book should be push down to make the left side of the spine to be more right angle. So you can increase adjustment on both NON-OP Plate 2 and OP Plate 2， and then making book to see LL and LR corners are ok or not.

LL corner is round: it means that the LL corner should be push down to make the LL corner to be more right angle, So you can increase adjustment on NON-OP Plate 2，and then making book to see LL corner is

LR corner is round: it means that the LR corner should be push down to make the LR corner to be more right angle, So you can increase adjustment on OP Plate 2， and then making book to see LR corner is ok or

Maintenance

5.1 Day/Month/Year Maintenance Daily Cleaning Procedures

After you have finished using the binder for the day, follow the following steps:

1.Close the clamps while the LED display flashing "LOAD BOOK" or "LOAD PAD". 2.Press "START" and "CLEAR" keys simultaneously. The clamp station will automatically

the left of the machine and LED display "NP SVC".

3. Clean the residual glue that might be on the nipping plates and plate surfaces.
4. Press the "START" and "CLEAR" keys, the clamp station will return to its home position. Open the clamps to the maximum position. Clean their surfaces and wax them.
5. Turn the DB-280 off.

Depends on how frequency you use the machine, we recommend that you should do the following maintenance at least once during three-month period.

1. Clamp Station

1. Open the clamps to the maximum position then turn off the power of the machine.
2. Take apart the clamps from the clamp station.
3. Clean the residual glue that might be on the clamps.
4. Install the clamps to the clamp station.
5. Turn on the power of the machine.
6. Clamp some inner pages to see if the clamps have been installed properly. If clamp adjustment need, please refer

to A1 section of Appendix for details.

2. Notching Station This is a monthly maintenance. However, we recommend that you should use vacuum to clean the paper dust on the notching station when the machine has made 2,000 books.

Warning: You must power off the machine in order to perform the notching blade maintenance.

1. Power off the machine.
2. Remove the notching covers.
3. Use the vacuum to clean up the paper dust.
4. Clean up the residual glue around the notching wheel, rollers and blade.
5. Clean the notching covers, notching blade, and rollers.
6. Check to see if the notching blade has been worn out or broken. If so, replace a new one.
7. Install the notching covers.

5.1.1 All operating components such as chains, chain sprockets, gears, racks shall be routinely added with lubricating oil or grease. 5.2.2 All rotating joints at spindle ends attached with oil cups shall be routinely filled with lube oil.

In case, when the control panel display error message, please refer to following step to correct.
