5.13 Adjusting the fabric lapping (both-side fabric edge trimming)
Take the following steps to adjust the fabric lapping.
When the presser foot has not been removed or replaced,
etc., skip steps (1) and (2), and start the procedure at step
(3).
(1) Check whether the side of the presser foot ① is parallel
to the slots of the stitch plate ② . If adjustment is
required, refer to "6.13 Replacing presser foot."
(2) Reduce the pressure of the presser foot to check
whether the presser foot moves up and down smoothly
and to check that there is no play at the left or right. If
adjustment is required, refer to "6.13 Replacing presser
foot."
(3) Adjust the differential feeding so that the fabric is sewn
to be flat.
(4) Adjust the lapped width of the upper fabric and lower
fabric using the height of the lower knife. (Refer to "5.10
Height of lower knife." )
(5) Adjust the right and left position of the lower fabric
using the right and left position of the lap former end.
(Refer to "5.11 Use of lap former." )
(6) Adjust the right and left position of the upper fabric
using the right and left position of the lower knife.
This adjustment also affects the position of the lower
fabric so check the position of the lower fabric as
well. (Refer to "5.12 Adjusting lapped width of upper
fabric." )
ＡＤＶＩＣＥ
Start the adjustment procedure from a state in which
there is a less amount of lapping between the lower and
upper fabric.
Even when the amount of lapping between the lower and
upper fabric is sufficient from the beginning, it is still
hard to determine whether the lapping is appropriate or
too much, and if the lapping is too much, fabric pinching
and other problems will occur in the finishing.
