LS-1340 Series
Cylinder-bed, 1-needle, Unison-feed, Lockstitch Machine with Vertical-axis Hook
T
With its larger needlebar stroke, larger lift of the presser foot, and newly
adopted double-tension mechanism, the machine sews beautifully with thick
threads (low count thread) and at higher thread tensions. This allows the
machine to sew a broad range of heavy materials.
* The LS-1340 is provided with a single-tension mechanism.
The newly developed mode of highly rigid rectangular feed guarantees
outstanding feed performance. In addition, the ratio between the alternating
vertical movements of the walking foot and presser foot remains unchanged
even when the material thickness changes. With this feature, the machine
sews multi-layered parts of the material consistently and without stitch gathering.
The machine is equipped as standard with a mechanism to correct uneven
material feed by making-micro adjustments to the bottom-feed.

•Higher lift of the presser foot •The maximum alternating vertical

•Compared with the elliptical feed, the
rectangular feed helps reduce
gathered stitches. •The ratio of alternate vertical

when the material thickness changes.
Excellent for the sewing of sharp curves.
Excellent operability and maintainability.
Sewing capabilities and feed performance
that respond to a broad range of uses in
the sewing of heavy materials.
The slimmed-down throat plate easily responds to the sewing of
small tubular articles with diameters as small as φ40mm.
This enhances the machine's ability to smoothly sew not only bags
and shoes, but also small articles such as wallets.
In addition to the standard type machine, a machine provided with
a gauge for small articles is available. (LS-1342, LS-1342-7)
The underside of the top end of the cylinder-bed is provided with an easy-
to-remove cover. This promises easy cleaning of thread wastes.
The stitch length can be easily selected by the stitch dial. The machine's
enhanced operability features include a clear view of the area around the
needle, placement of the bobbin thread winder on the front face of the
machine arm, and a large handwheel(φ160mm).
A knee-lifter mechanism is built in the bed. This reduces the pressure
required to operate the knee-lifter and facilitates setup.
The machine’s full-open-type top design makes adjusting works easier.
The machine comes with a lubricating mechanism that uses a centralized
oil wick. This substantially reduces the time and trouble required for
oiling the machine. (The hook needs manual oiling with an oiler.)
A walking foot mechanism is built into the machine arm to prevent oil
from scattering .
The vertical stroke of the presser
foot and walking foot (amount of
alternating vertical movement) can
be easily changed with the large
dial mounted on the top of the
machine head. The sewing speed
is automatically regulated based
on the vertical stroke setting.
This ensures ideal sewing
conditions at all times.

For sewing processes that handle heavy materials or multi-layered parts of material, the
alternating vertical movements of the walking foot and presser foot can be quickly set to
maximum by pressing the DL switch.
The result is beautiful seams free from gathered stitches.
The machine is provided with both a hand switch and
knee switch.
With just a light press on the one-touch type reverse
feed button, reverse feed stitching is actuated.
The machine handles thread counts from #30 to #5.
Its highly rigid thread trimming mechanism cuts the thread
without fail. The machine can be applied to a broad range
of sewing processes, including the sewing of bags.
Since the needle thread-tension-release
solenoid is fitted on the rear face of the
machine head, the area around the needle
entry is easily viewable. This substantially
improves the operability of the machine.
The throat plate and feed dog are provided
with a gauge that offers an excellent
capability for the sewing of sharp curves.
These gauges are especially useful for the
sewing of curves of bags and leather
cases.

installed on the LS-1342-7.)
The DL device cannot be used alone. It must be used in a set together with the automatic
reverse feed function and AK-147E.
To mount the DL device to a machine provided with auto lifter and automatic reverse feed
function, the DL-26B should be purchased separately.
To use pneumatic auto-lifter and reverse feed function in combination with a machine
that is without automatic thread trimmer, select AK147A or AK147B.
