When special types of paper are folded, deviations from the calculated and displayed
NOMINAL values may become necessary.
Individual corrections can be made by means of the numbered setting knobs at each
roller.
The fold rollers and delivery shafts with the matching setting knobs are arranged
according to the following scheme:
1

The setting knobs are equipped with scales (1).
With their help settings with a precision of 0.01 mm
are possible.
An additional scale (2) indicates adjustments in
steps of 0.5 mm.
To increase the roller gap, turn the setting knob
counter-clockwise.
To reduce the roller gap, turn the setting knob
clockwise.
When the roller gap is changed by more than 0.5 mm,
the values on both scales must be added.
Example: 0,5 (2) + 16 (1) = 0,66 mm
The layout sketch shows a fold unit with 4 fold plates.
There are no fold rollers 4 and 5 in a fold unit with 2 fold plates.
The delivery shaft has the number 4.
