The machine comes with a silicon oil lubricating unit, thread spreading mechanism and thread trimming mechanism which
trims the thread without fail, thereby consistently ensuring beautifully-finished seams for light- to medium-weight
materials. The appearance of the machine is restyled, and it is now colored in a refreshing urban white.
Needle thread draw-out mechanism
The machine is provided with
mechanisms to enable upgraded sewing.
The machine comes with a thread spreading
mechanism and an adjustable needle guard to
prevent stitch skipping. The thread clamp
mechanism, tension release mechanism and needle
thread draw-out mechanism enable the machine
to leave thread of a uniform length after thread
trimming, and prevent slip-off of the needle
thread. All of these mechanisms contribute to
upgraded sewing.

The machine finishes beautiful seams in elastic and light-weight
materials. Furthermore, the differential-feed can be adjusted with the
simple operation of a lever, thereby enabling the machine to respond
to the requirements of many different kinds of sewing.
Using a lever, the
differential-feed ratio
for stretch stitching
or gathering stitching
can be easily
adjusted.

An easy-to-operate, high-precision
presser foot, feed dog and thread
draw-out mechanism have been
developed for this sewing machine so
that any operator can finish seams of
the highest quality.
The machine flexibly adapts to a
wider range of light- to heavy-weight
materials, process changes, and
sewing specifications, including
partial shirring.
The machine incorporates many
functions and places a great deal
of importance on higher product
quality.
The machine comes with many different
functions to prevent uneven material feed
and puckering for higher-quality seams.
The machine is adaptable to a wider variety
of light-to heavy-weight materials and takes
full advantage of top-feed mechanism.
This enables unskilled operators to finish
seams of consistent quality.
Needle thread clamp mechanism
and sliding presser foot
Safety stitching or reverse feed stitching
with a simple lever operation.
Safety stitching (condensation stitching) the
perfect method of preventing loose stitches, or
reverse feed stitching (back-tacking) can be
alternated through the simple adjustment of the
stopper of the reverse feed lever. Either sewing
method can be used.
The machine is best-suited for sewing
elastic materials.
The differential-feed is the best-suited feeding
device when sewing elastic materials including
double-jersey or light-weight materials such as
satin or georgette. Beautiful, elastic seams are
created, while puckering, thread breakage and
thread fraying are all prevented.
Presser foot
●Bottom and variable top-feed
mechanism
The top-feed amount can be adjusted
independently of the bottom-feed. The
maximum lift of the walking foot is 3mm.
The top-feed dog has been designed so that the
operator can smoothly place the material to be
sewn on it. Furthermore, the gauge can be easily
replaced and stitch adjustment can be performed
without difficulty.
The machine comes with a forced lifting mechanism for the
top-feed dog. This enables the operator to place the material
to be sewn on the top-feed dog more smoothly. The machine
incorporates its exclusive chain-off thread presser pedal foot,
which improves seam quality and ease of operation.
The exclusive gauge comes in five different types, and the
gauges can be replaced in a simple procedure. This facilitates
the required adjustment when changing the needle count.
Thread triangle
●Thread spreading mechanism
The thread spreader is for reverse feed stitching. It also plays an
important role during normal feed stitching, helping create finished
seams with higher consistency and preventing stitch skipping.
Beautifully finished seams.
Provided with a sliding presser foot and a silicone
oil lubricating unit as standard, stitch skipping and
puckering are prevented. Furthermore, the silicone
oil lubricating unit prevents the needle from
overheating, and allows foundation yarn or
synthetic thread to be used without breakage
during sewing. These features assure beautifully
finished seams with consistency for light- to
medium-weight materials.
Change of sewing method with a simple lever
operation.
The sewing method can be alternated between stretch
stitching and shirr stitching with the simple operation of
a lever. This lever is also used to adjust the differential-
feed ratio.
The machine is capable of gathering and
partial shirring.
A gathering attachment (S060), intermittent gathering
attachment (S061) and partial shirring device (PF5) are
optionally available to enable the machine to perform
consistent gathering and partial shirring.
Replaceable gauges such as the gauge for light-weight
materials and the urethane feed dog are prepared in
accordance with the applications of the machine.

●Uneven material feed is prevented by adjusting the top-feed
The machine works effectively for processes
which require partial shirring as long as the
partial shirring device (PH-3) is used in
combination with the partial shirring dial.
The partial shirring device comes in two
different types, the kneepad drive type and
the pedal drive type.
