BAUMSET ADJUSTMENT
1.0 Adjustment of Folding Rollers
Folding accuracy is determined largely by precise
adjustment of the folding rollers.
Using the Baumset precision adjustment device, the
correct setting of the rollers can be made simply by inserting
the appropriate paper thickness between the adjustment
plates. (See Figure 22)
With multiple thicknesses, insert single strips of the
paper being folded equal to the number of sheets passing
through that roller combination..
Since the adjustment spindle acts directly on the folding
rollers, clearance settings are exact.
Another method for setting the folding rollers is to insert
paper strips between them by touch, the pressure adjustment
being made by turning the knurled screw.
The numbers on the Baumset adjustment knobs corre-
spond to the buckle-plate numbers into which the sheet is
fed. All upper buckle plates have odd numbers while the
plates below are even.
The Baumset adjustment device is correctly zeroed at the
factory. If any adjustment is necessary, strips of single paper
thickness should be placed under every adjustment plate. The
folding rollers are then reset by drawing strips of uniform
thickness through the appropriate pair of rollers as far as
possible to the other side.
At the same time, the knurled screws are adjusted so that
the strips can be withdrawn when medium drag is felt. When
this operation is complete, the dial rings are reset to zero.

A double sheet strikes the scanner on the microswitch,
interrupting the sheet flow-through.
With single sheet thickness, the scanner remains
untouched and sheets move freely.
