CORD TRIM ADJUSTMENTS
Gimp Pull Back
A gimp pull back is provided to ensure that there is enough gimp to start the next buttonhole. Spring A
acts as a clamp and also adds tension on gimp. Before performing this adjustment, remove gimp pull back
assembly B from the machine by pressing inward on floating pin C, which is located on the race. Loosen
screw D and move the spring up or down until its top edge is slightly under the top of the gimp hole. The
gimp should slide through the hole freely, but not be able to be pulled back through the hole. Once the
gimp can slide through the hole freely, re-tighten screw D.
If tension is incorrect, adjust by slightly bending spring A in or out (in creates more tension; out creates
less tension) as necessary.
Weight E pulls gimp back through the
hole in throat plat at the end of the cycle.
If the weight is adjusted forward, it
increases the amount of starting gimp; if
the weight is adjusted so it sits back, it
decreases the amount of starting gimp. To
adjust the length of the starting gimp,
loosen screw F and move stop G up or
down to obtain the desired amount of
starting gimp.
Stitch Increase / Decrease Wedge
Wedge A is used to add or remove stitches to / from the eye of the buttonhole. To adjust, turn the left hand
crank until roll C is located on the ramp of the wedge. Loosen screw B and move the wedge forward or
backward (moving the wedge forward increases the number of stitches backward decreases the number of
stitches) as necessary.
