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.

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.
