5-5. Adjusting the belt loop tension
5-6. Setting the belt loop thickness
When you have changed the belt loop, you need to re-adjust the
A
belt loop tension without exceptions.
Press the belt loop tension button
screen.
The more the belt loop tension is adjusted in a negative direc-
tion, the less the belt loop tension becomes. (The belt loop ten-
sion can be set and stored in memory on a sewing-pattern by
sewing-pattern basis.)
As a guide, adjust the belt loop tension so that the entire length
of the belt loop fed from the belt loop feeding section and
clamped at the belt loop clamping section is shorter than the
entire belt loop length displayed when selecting a sewing pat-
tern by approximately 1 mm.
If the sewing machine is operated under a high belt
loop tension, the entire length of the belt loop fed
becomes shorter than required. In this case, prob-
lems such that the belt loop cannot be sewing at
the predetermined length or that the cut end of the
belt loop is not straight can occur. To prevent such
problems, adjust the belt loop tension adequately.
When you use a new belt loop, you need to set the belt loop
thickness without exceptions. If the belt loop has multi-layered
parts (splices), thickness of the multi-layered part has also to
be set.
Press belt loop thickness teaching button

der the multi-layered part detecting section.
1. If the belt loop thickness is smaller than the pre-
determined value, the belt loop presence/absence
detector of the belt loop drawing device may
determine that the belt loop is absent even if the
belt loop is present. If the aforementioned error
B
occurs, operate the sewing machine with the belt
loop presence/absence detecting function dis-
abled.
2. As a guide, the belt loop thickness is 1 to 1.8 mm.
If the belt loop thickness exceeds the aforemen-
tioned range, the belt loop clamping section and
the work clamp foot of the sewing machine can

interfere with each other. To prevent this, be sure
to perform trial stitching in prior to confirm no
interference between them. Then, start sewing.
