Product catalog summary
Introduction
The document introduces a new generation of computer-controlled shape-tacking machines designed for sewing seatbelts and heavy-weight materials. The models include LK-1941ZA, LK-1942HA, and LK-1942GA, each tailored for specific material weights and equipped with advanced features to enhance productivity and seam quality.
Specifications
The machines offer a sewing area of 60 mm (L) × 100 mm (W) and a maximum sewing speed of 2,200 rpm. They are equipped with a full-rotary 3-fold capacity hook, reducing bobbin thread replacement frequency and improving efficiency with thick threads. The machines support various yarn numbers and are designed for different applications, including seatbelts and heavy-weight materials.
Features
The machines incorporate JUKI's unique 3-fold capacity hook and a needle thread feeding device to prevent slippage. They feature a semi-rotary tension system for higher needle thread tension and a heat cutter for reliable thread trimming. The electronic feed system allows easy selection and programming of sewing patterns, eliminating the need for mechanical feed cam replacements.
Advanced Capabilities
For extra heavy-weight materials, the machines are equipped with a high-power direct-drive motor, a higher-torque stepping motor, and a pneumatic work clamp. The intermediate presser prevents material flopping, ensuring high-quality seams. The machines also offer adjustable features for the intermediate presser's height and stroke.
Options and Accessories
Optional accessories include a handy programming device (PGM-7B), a needle cooler, a silicon oil tank, and a thread-tension-releasing device. The machines can be customized with various parts like a 3-pedal unit, heat cutter, and work clamp foot for specific applications.
Environmental and Safety Considerations
The document emphasizes the company's commitment to environmental management, including energy conservation and recycling. It also advises reading the instruction manual for safety before using the machines.
Conclusion
The LK-1941ZA, LK-1942HA, and LK-1942GA models are designed to improve productivity and seam quality for heavy-weight materials, offering advanced features and customization options to meet diverse industrial sewing needs.
