Cylinder-bed, 1-needle, Unison-feed, Lockstitch Machine with Vertical-axis Hook (With large vertical-axis hook, gauge for small articles, and automatic thread trimmer)
The slimmed-down throat plate easily adjusts to the sewing of small tubular articles with diameters as small as φ40mm. This enhances the Juki LS-1340 Series ability to smoothly sew not only bags and shoes, but also small article such as wallets. The newly developed mode of highly rigid rectangular feed guarantees outstanding feed performance
Sewing capabilities and feed performance that respond to a broad range of uses in the sewing of heavy materials.
- With its larger needlebar stroke, larger lift of the presser foot, and newly adopted double-tension mechanism, the Juki LS-1340 Series sews beautifully with thick threads (low count thread) and at higher thread tensions. This allows the Juki LS-1340 Series to sew a broad range of heavy materials. * The Juki 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.
- 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)
Excellent operability and maintainability
- 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 machine is provided as standard with an instantaneous change-over device for the alternate vertical movement amount (DL device).
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.
A helpful automatic reverse feed function is provided as standard.
With just a light press on the one-touch type reverse feed button, reverse feed stitching is actuated.
Thread trimming without fail.
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.
