Computer-controlled Shape-tacking Machine with Full-rotary 3-fold Capacity Hook (For extra heavy-weight materials with intermediate presser)
[ Sewing area : 60 mm (L) × 100 mm (W) ]
The following features promise improved sewing capabilities for extra heavy-weight materials: A high-power, direct-drive motor that drives the needle with increased material-penetrating force; a higher-torque stepping motor that increases the feed efficiency, and a pneumatic work clamp that increases the material clamping force.
The sewing pattern can be changed with ease
With its new electronic feed system, the operator can select and use the sewing pattern entered. When changing a sewing pattern, the conventional mechanical bartacking machine requires the replacement of a feed cam. Since the new electronic machine no longer uses a feed cam, this operation is no longer necessary and costs are substantially saved.
With the handy PGM-7B programming device (optional), sewing patterns can be programmed on the main unit of the machine.
The Juki LK-1940 Series demonstrates a high-speed sewing capability of up to 2,200 sti/min for dramatically increased productivity.
The Juki LK-1940 Series is equipped as standard with a full-rotary 3-fold capacity hook. The hook reduces the frequency of the bobbin thread replacement, enhancing efficiency in sewing with thick thread.
The machine offers improved seam quality and sewing capabilities when sewing heavy-weight or extra heavy-weight materials.
The following features promise improved sewing capabilities for extra heavy-weight materials: A high-power, direct-drive motor that drives the needle with increased material-penetrating force; a higher-torque stepping motor that increases the feed efficiency, and a pneumatic work clamp that increases the material clamping force. Adoption of JUKI’s unique 3-fold capacity hook and a profound knowledge of sewing grounded on years of extensive sewing research help eliminate sewing problems and improve seam quality.
Standard device for G type or Z type. Needle thread feeding device: Feeds an adequate amount of needle thread in advance to prevent slippage from the needle when using bonding thread or the like. Semi-rotary tension: Applies higher tension on the needle thread.
The needle hole guide for the Z type machine is optimally suited for the sewing of seatbelts and ensures seams of extremely consistent quality.
Higher lift of the feeding frame (max: 25mm) enables easy placement of a material on the machine.
