End of sewing
Beginning
The remaining length of thread at the end of sewing
is substantially shortened to approximately 5mm.
The machine cuts thread as thick as #5 without fail.
Even if the needle thread is clamped under the
presser foot or walking foot, the machine draws the
needle thread onto the underside of the material
without fail, leaving no exposed thread on the right
side. The needle thread drawn onto the underside of
the material can be sewn under the seam.
The end-of-sewing thread is kept in the seam
allowance both at the beginning and end of sewing
and does not jut out from the material edge.
This function eliminates the need for thread snipping.
The operator is able to concentrate on sewing work
without having to perform thread snipping work,
thereby dramatically increasing productivity.
The frequency of scissor use by the operator is
significantly reduced, thereby preventing accidents
in which the scissors damage the material.
Conventional machines
Rectangular feed
Alternating vertical
movement mechanism
•Compared with the elliptical feed, the
rectangular feed helps reduce gathered
stitches.
•The ratio of alternate vertical movement
remains unchanged even when the
material thickness changes.
The newly developed mode of highly rigid rectangular feed
guarantees outstanding feed performance. In addition, the ratio
between the alternating vertical movements of the walking foot
and presser foot remains unchanged even when the material
thickness changes. With this feature, the machine sews multi-
layered parts of the material consistently and without stitch
gathering.
The vertical stroke of the presser foot and walking foot (amount of
alternating vertical movement) can be easily changed with the
large dial mounted on the top of the machine head. The sewing
speed is automatically regulated based on the vertical stroke
setting.
This ensures ideal sewing conditions at all times.
The machine is equipped as standard with a mechanism to correct
uneven material feed by making-micro adjustments to the bottom-
feed.

Thread snipping work that has traditionally been required by
conventional machines can now be virtually eliminated, thereby
drastically increasing productivity.
In addition, jut-out thread problems or accidents in which the
material is damaged by scissors during sewing can be prevented.
The machine contributes to reduced cost and upgraded quality in the
sewing of car seats.
