5.3.4 Cover Hinge Screen
MODE 3 Cover hinge
This is a mode especially for book cover make
Following are 2 pages of this mode, in which you can input 2 parameter.
SPINE and THK, Spine means the first spine line to the leading edge, THK
means the thickness of the book, namely the spine width.
2 parameters leads to 4 line, the other 2 is 8mm outside of 2 spine lines as
hinge lines.
Following drawing illustrates.
5.3.5 Progressive Screen
MODE 4 Progressive crease
If you want to shut down the function, press 1, enter, screen will jump to the
Ready Screen.

331 Auto Creaser 14
If you want to active the function, press 2，enter，Screen will jump as follow
to setting for the progressive crease:
Progressive crease performance is as follow, each job has 4 basic parameter:
1. Initial position 2.Progress Depth
3. Progress type (Inc/Dec/Inc & Dec) 4 Total Sheet
If all the sheets creased
on same position, the
bounded book can not be
turned over lay flat like this
drawing.
With 3 kinds of crease
mode, even thick paper
can be turned over very
easily and lay flat after
binding.

331 Auto Creaser 15
The illustration for V mode is as following
Define the first position and crease gap and the qty in one
batch, The first page will be one line as reference, and
following sheets will be 2 creases that goes further
successively to the reference line .
In this way the book can be folded with a square back after
sandel stitched
Effect of above 4 parameters is as above drawing
While progress crease function is activated and all setting is
done, screen will jump to the main operation mode. But the screen is different,
and it has only 1 page. As follow:
Press , goes to MODE 5.Press again, goes to MODE 6
5.3.6 Save a Job
MODE 5 Save Job
Frequently used crease data can be saved and recalled, so that user don’t
have to input data each time. The system at most saves 30 jobs.
How to save a job?
a. See MODE 2, Let’s input a job, say, 10, 20, 30, 0 , 0 ,0.
b. Press 2 times, we go to Save job Mode.

screen jump to main operation MODE, high speed is chosen.
5.3.9 Recalibration Screen
MODE 8 Recalibrate
If the Crease line gap is stretched or shirinked, the crease tolerance will be
accumulated as crease line increased. For a quick calibrate, we operate on
Recalibrate mode.
1. Measure the real length of a paper
2. Input the real length of the paper as following (say 420mm)
3. Press , machine runs.
4. Pass the paper. And the Recalibrate is done automatically.
Note: If the input date is more than 3% tolerant to the real length, it fails
5.4 Hardware Setting
5.4.1 Skew adjustment
If it is found the crease is skewed (not vertical to the paper side), you need to
adjust the feeding angle to get a satisfied performance.

331 Auto Creaser 18
Fixed side guide is the hardware where we adjust the skew.
As per above picture, the guide is fixed by 2 screw, rear one is through a slot
hole. We can loosen the screw , and move the side guide a bit, so that the
feeding direction is micro adjusted to compensate the skew issues.
5.4.2 Crease Depth
Crease depth is important to crease quality. It just depends on the gap
between male die and female die. Depth should be adjusted according to the
paper thickness. Low Depth will perform a not clear crease. But a high Depth
may cause cracking, causing system take it as a double feed.
The adjustment is also needed if the crease depth are not balance on both
sides.
To adjust the Depth:
Open the safety cover, you can see 3 Allen screws.
Turn the screw un-clockwise will increase the depth, Vice versa.
Normal
Not balanced
Too light
Too heavy
Crack edge
