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 seized when sewing (during the last section of the backward
movement the cylinder is pressureless).
–
Turn the stop screw 10 in such a way that - if the folder is lowered -
the stop screw 10 abuts on the stop 11 (make sure that it snaps in).
–
Adjust the spring pressure with screw 12 in the stop screw 10 so
that the folder is pressed back.
