Fig. 122: Setting the stroke movement of the folder (4)
Stop screw with spring
Proper setting
Adjust the stop screw (7) in such a way that the distance of the folder sole
to the sliding plate (depending on the fabric) is approx. 1 - 2 mm when the
folder is lowered.
The incorporated spring presses the folder back such that the piping strip
is reliably seized during sewing (the cylinder is depressurized during the
last section of the backward movement).
To set the stop screw with spring:
1. Turn the stop screw (7) in such a way that - with the folder lowered -
the stop screw (7) abuts on stop (8) (make sure it snaps into place).
2. Set the spring pressure using the screw (4) in the stop screw (7) so
that the folder is pushed back.
