Features
| MH-481/MH-481-5(4) |
| |
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. |

|
 |
| 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. |
|
 |
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. |
|
|
|
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. |
|
|
|
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. |
|
| MH-481/MH-484-5(4) |
 |
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. |
|
|
|
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. |
|
| |
|
|
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. |
|
|
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. |
|
| MH-486-5(4) |
| |
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 top-feed
amount can be adjusted independently
of the bottom-feed. The maximum lift
of the walking foot is 3mm. |
|
|
 |
|
|
|
The
machine is also capable of performing partial
shirring. |
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. |
|
| |
|
|
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. |
|
|
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. |
