Responsiveness to materials has been thoroughly
investigated to improve "seam" quality.
A thread tension control mechanism has been developed for each type of sewing machine in
order to achieve the best-suited thread tension for its purpose. The sewing machine for jeans
and heavy-weight materials (G type) produces well-tensed seams by the optimization of the feed
mechanism. Furthermore, the G type machine comes with the new thread trimmer mechanism
which promises increased reliability.
The best-suited thread tension is achieved
according to the sewing specifications
Two different types of thread tension controllers
have been developed.
The needle tension controller comes in two different mechanisms
according to the type of sewing machine. For the A and F types,
seam quality free from puckering and irregular stitches is
promised. For the S and G types, the sewing range has been
broadened to produce well-tensed seams even when thick thread
is used.
A and F type
Independent right and left needles type
thread tension controller
Highly reliable thread-trimming mechanism
Our direct-acting thread trimmer mechanism, which spreads
thread without fail, has been further improved. The thread trimmer
trims the needle thread and bobbin thread without fail even when
thick thread is used. In addition, the thread trimmer's bobbin
thread retaining force has been increased.

Standard type thread tension controller
Wire type and round-hole type needle bar
thread guide
Two different kinds of needle bar thread guides (needle clamps),
the wire type and round-hole type, have been developed
according to the type of sewing machine. The wire-type needle
bar thread guide has been adopted for the A and F types which
require the sewing capability to sew light-weight materials and
foundations without puckering or irregular stitches. The round-hole
type needle bar thread guide has been adopted for the S and G
types which sew materials requiring well-tensed seams. In
addition, the G type is provided as standard with the presser foot
with guide which is effective for the topstitching process.

Material-friendly micro-lifter mechanism
The presser foot can be lifted by a minute amount by adjusting
the eccentric pin located in the presser lifter lever section.
When sewing shaggy and elastic fabrics, the load applied to the
material is reduced by slightly lifting the presser foot. Materials are
handled more easily and are finished without sacrificing the
inherent texture of the material.
