2-needle, Needle-feed, Lockstitch Machine
LH-3128
LH-3128-7
(with automatic thread trimmer)
● The tension applied to the bobbin thread has been reduced and the
needle thread path has been thoroughly renovated to achieve highly
consistent feed of the needle thread.
thread breakage and isolated idling loops can be therefore prevented,
enabling the machine to produce beautifully finished seams with
consistency.
● After the gauge has been replaced, the machine can be adapted to
the newly installed gauge only by adjusting the clearance provided
between the blade point of the hook and the needle.
it is not necessary to change the hook timing in accordance with the
gauge. As a result, the length of time required to replace the
gauge is dramatically reduced.
2-needle, Needle-feed, Lockstitch Machine
with Organized Split Needle Bar
LH-3168
LH-3168-7
(with automatic thread trimmer)
● The organized split needle bars which
enable either the left or right needle
to stop independently of the other
can be changed over by simply
operating the lever, thereby saving
labor in corner stitching.
2-needle, Needle-feed, Lockstitch Machine
with Organized Split Needle Bar and Large Hooks
LH-3188
LH-3188-7
(with automatic thread trimmer)
● The organized split needle bar mechanism makes it possible to stop
or reset the left or right needle by operating a one-touch utility lever.
● The machine produces neatly finished stitches at corner parts of the
material.
● Improved thread tension and presser foot dramatically upgrades the
seam adjusting ability.
The range of thread counts that can be used is widened.
2-needle, Bottom-feed, Lockstitch Machine
LH-3120
● The machine has adopted a bottom-feed mechanism.
the machine to perform sewing with a low tension applied to the
material while preventing puckering and stitch skipping, thereby
improving consistency of seam quality.
● The machine is capable of adapting to the sewing of light-weight
materials and newly-developed materials.
machine is exceedingly effective to the process to sew top center
plaits of shirts and the sewing of foundation.

2-needle, Needle-feed, Lockstitch Machine
with Large Hooks
LH-3178
LH-3178-7
(with automatic thread trimmer)
● Our investigation of the thread take-up stroke and
other mechanisms results in the reduction of irregular
stitches. Even at high speed, the machine performs
sewing as consistently as the standard hook machine.
The machine can make the most out of the
advantageous features of the large hook, upgrading
the finished quality of heavy-weight materials and
improving efficiency.
