Stopping the machine
To interrupt the folding process at any time, press the Stop key.
This will stop the machine in a controlled manner.
The sheets already in process will be folded and delivered before the
machine stops. The stacker belts will move all folded sheets to the end of
the stacker table for easy removal.
Unless there is an emergency situation, DO NOT stop the machine by
turning power off by the main switch or wall socket. Doing this while the
machine is folding will result in a paper jam inside the machine.
Fine tuning the fold
There can be many reasons for a fold to be slightly off. These include the
paper composition, size and direction of grain. Also, folding speed and
ambient conditions like temperature and humidity can have an effect.
To be able to correct a fold, you must understand what is happening in
the folder:
The top sheet of paper is fed into the folder and is driven by rollers (1)
and (2) into fold plate 1.
The paper continues into the fold plate until it hits the stop. Since the two
rollers are still driving the paper, a buckle will form at the entrance to the
fold plate and will, eventually, be caught between fold rollers (2) and (3).
This is how the first fold is made.
The folded edge will be guided by the deflector into the grip of rollers
(3) and (4). Here the same thing happens as in the first fold plate and a
second fold is made.
Note: If a single fold is selected, the second fold plate is automatically
closed off and the folded sheet is routed past it.
The folded sheet is now guided by the second deflector into the grip of
rollers (5) and (6) where it is fed out onto the stacker.
It is obvious that the position of each fold plate stop determines the
length of the fold resulting from it. Keeping this in mind, it is easy to make
corrections to each fold by simply moving the relevant stop in or out. You
only need to know which end of the sheet entered the machine first to
recognize which was the first fold and which was the second.
Fold corrections can be made with the machine stopped or with it
running:
Correcting a fold with the machine stopped
Select which fold you want to correct by pressing the Fold 1 or Fold 2
key. (If a single fold is set, the Fold 2 key will not respond).
The display shows for example:
T0
CHG:
Change the value by pressing the
confirm the new setting.
The fold is now set and the display shows:
TEMP JOB: 0
If you try to start the machine without pressing Enter, the display will
ask:
USE NEW SETTING?
YES: Enter.
The machine will not start until you press either Enter or
Correcting a fold with the machine running
Select which fold you want to correct by pressing the Fold 1 or Fold 2
key. (If a single fold is set, the Fold 2 key will not respond).
The display shows, for example:
FOLD 1 = 148.0
FOLD 2 = 74.0
Change the value by pressing the
instantly by taking a folded sample from the stacker.
This procedure should only be used to correct small errors; otherwise
you will produce many reject sheets before you get the fold right.
The correction display will remain until you either press Enter, Speed or
you stop the machine.
FOLD 1 = 148.0
