14.6 Conveyor belt faults
10) The upper conveyor
belt does not run
straight, but moves to
the left or right. 1) The belt run adjustment is not
set correctly.
2) Dough residues have built up on
the drive roller. This increases
the diameter of the drive roller and
causes the strip to wander to the
thinner diameter of the drive roller.
1) Straight running can be adjusted
with the small adjusting wheel for the belt
adjustment. If the wheel is turned to the
left, the belt also moves to the left.
If the wheel is turned to the right,
the belt also moves to the right.
The adjustment must be made in small
steps and you can easily let the machine
run for a few minutes to adjust the
running of the belt step by step.
2) If the belt cannot be adjusted, remove
the belt and remove any dough residue
that has settled on the drive shaft of the
drive roller.
