Where cutting precedes sewing the incision opens to enable the
piercing needle to sew the left and right seam rows cleanly without
piercing the cut edge of the material.
On machines where cutting follows sewing the material is kept taut for
the sewing process.
A spread of 1.5 mm is normally sufficient.
The workpiece is spread just before sewing begins. The clamp plates
are forced apart by the two pins 1.
The left and right sides must be evenly adjusted so that both clamp
plates execute an equal lateral movement.
Caution: danger of injury
The material spread must only be adjusted with the machine switched
off or in the firm hold position.
Adjustment
The stop screws 2 can be reached through the holes 3 on both sides of
the machine with an Allen key.
Adjust the stop screws on both sides so that the required spread is
–
achieved.
