Custom patterns can be created
on the operation panel with ease.
● Custom patterns
• Original sewing patterns can be quickly
created and stored in memory.
• Max. 20 patterns, Max. 500 stitches /pattern.
(Example)
Abundant variation in stitching.
● Mirroring of scallop stitches
• The machine produces beautifully finished
scallop stitches on front part of a girdle. etc.
• For the scallop stitch, the starting position for
sewing can be selected between the top and
bottom of a scallop.

✱
The thread tension mechanism, bobbin
case and feed timing have been improved
to produce soft-textured seams.
✱
The machine is equipped with a hook-
driving shaft-offset mechanism which
places the hook-rotating shaft off-center
from the center of zigzag stroke of the
needle. This mechanism allows the blade
point of the hook to catch the needle
thread every time regardless of the needle
throwing direction. As a result, the
machine is immune to sewing troubles
such as stitch skipping and thread
breakage, annoyances likely to occur with
the conventional machine, especially
when the needle throws to the right.
✱
You can quickly create an original stitching pattern on the operation
panel and then try to sew it on a trial basis.
A wider variation in design enables the machine to respond to wider
applications, such as foundations, ladies' wear and men's wear.
✱
The machine requires neither a programming device nor ROM writer.
● Condense custom patterns
• The user can specify original condense custom patterns.
This type of pattern is very effective at producing improved
bartacks and keeping seams from being left undone.

The position at which the
blade point of the hook
tacks the thread is almost
uniform.
✽Automatic reverse feed function is required.
• Start and end of sewing: A maximum of
20 different patterns, with a max. of 64
steps/pattern.
• The machine, with its automatic thread
trimmer, is able to leave shorter thread
after thread trimming as compared with
the conventional machines.

● Setting the number of stitches
for a blind stitching pattern
• The user can set the

(3 to 250 stitches.)
● Setting of the left and right stopping positions

• These settings are
effective when performing
corner stitching for label
attachment or decorative
stitching on the fronts of
girdles.
● Program stitching
• As many as 20 different constant-dimension
stitch patterns can be programmed.
The maximum number of stitches that can be
set for one step is 500.
● Multi-layer stitching
Step 2
• It is used for reinforcing
fastening stitches or bartacks.
✱
For the minute-quantity lubrication type hook,
the inner hook is finished with titanium to keep it
from becoming hot. The machine requires only a
very small quantity of oil. This prevents oil stains
on the material and the improves durability of the
hook. In addition, the hook configuration is
carefully designed to avoid needle breakage.
