However, if small formats with a length
below 20 cm are to be folded, the sheet
gap can also be adjusted by means of
a lever (2).
The adjustment changes the speed of the
suction drum, i.e. different speeds of
feeder and fold rollers result in different
sheet gaps.
A smaller sheet gap increases the speed
of the folder, independent of the cycle
frequency.
Lever in right position:
Adjustment of small formats below a length of 20 cm.
Lever in center position:
Setting for all "normal" folds.

The adjustment can be made with the machine
running.
To increase the sheet gap, always use the potentiometer (1) on the
operator panel, do not use the lever.
