12.9 Stop screw for the pick-up folder
Caution: Danger of injury !
Adjust the stop screw for the pick-up folder with utmost caution
when the sewing unit is running.
Standard checking
The stop screw 10 has to be adjusted in such a way that - with the
folder lowered - the distance between the folder sole and the sliding
sheet amounts to approx. 1 - 2 mm. (dependent on the fabric).
The incorporated spring presses the folder back s o that the piping s trip
is safely seized when sewing (during the last section of the backward
movement the cylinder is pressureless).
