1-needle, Double Chainstitch Machine
MH-481
MH-481-5(4)
(with an automatic thread trimmer)
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 (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.
1-needle, Double Chainstitch Differential-feed Machine
MH-484
MH-484-5(4)
(with an automatic thread trimmer)
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.
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.

1-needle, Double Chainstitch, Bottom & Variable Top-feed
Machine with an Automatic Thread Trimmer
MH-486-5(4)
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.
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.
incorporates its exclusive chain-off thread presser pedal foot,
which improves seam quality and ease of operation.
