1.17 Opening path of the flap clamp
The opening path of the flap clamps (4) must be adju-
sted in a way that the flap clamp presses with its com-
plete length onto the main clamp, when the flap clamp
cylinder is driven out.
Loosen both allen screws (1) at the flap clamp to be
adjusted and adjust the cylinder (2) correctly. Tighten
both allen screws (1) again.
1.18 Photo cell foil
A photo cell foil (5) is fixed to each clamp (3). This al-
lows an always good detection of the flap.
Clean the foil with a clean cloth from time to time. If the
foil is damaged, it must be changed.
1.19 Check/change clamp rubber
<power off> <release pressure>
There are moss-rubber strips below each main clamp. If
there are problems of the sewing material and the clamp,
these rubber strips should be checked.
Demount the clamp by loosening the allen screw (1).
The moss rubber strip is fixed with three screws (2).
If the rubber is damaged, loosen them and change the
strip.
Fix the clamp arm again and adjust it.
Hint
When working with thick sewing material it is advan-
tageous to use a thicker clamp rubber or mount a
heightening.
