from buckle plate.

the roller table of the 2nd
station or fails to run into
the 1st buckle plate of the
2nd folding station.
Wrinkling after the 1st
fold, either across or
parallel.
Crooked perforation after
1st fold.
Sheet corners buckled
up or down after the
1st fold.
CAUSE
Product too thick for folding.
Not enough roll pressures.
Electrostatic charge in
product caused by friction
with rollers and deflectors
and also relatively low
humidity.
Damping rods and sheet holder
set too low.
Register guide not at right-
angles to the folding rollers.
Sheet drawn too sharply against
the register guide causing a wave
to form.
Buckle plate feed stop not
parallel to the incoming sheet
edge.
Folding rollers set too tight.

REMEDY
Consult Baum technical rep.
Check Baumset settings.
Fit discharge unit at the
exit to the 1st station
or arrange for appropriate
humidity on the premises.
Raise as necessary.
Set angle correctly.
Insert fewer balls or use
lighter ones.
Correct buckle plate stop
setting.
Slacken roller setting.
Reset.
Check and reset as
necessary.
Set to zero position.
If the corners are buckled
upwards, set the upper
sheet deflectors back
evenly; if the corners are
buckled downwards, the
lower deflectors must
similarly be set back
evenly by underlaying
pieces of card. In no
circumstances alter the
basic setting of the
deflectors.
