Kingsew KS-GNDJ-20508 Series Integrated Double Needle Lockstitch Machine with Automatic Thread Trimmer

Description

Kingsew KS-GNDJ-20508 Series Integrated Double Needle Lockstitch Machine with Automatic Thread Trimmer

High-speed, computerized two-needle flatbed lockstitch machine designed for precision parallel topstitching, decorative seam work, and structured assembly on medium to heavy fabrics. The Kingsew KS-GNDJ-20508 Series (available in 20508M for medium-weight and 20508C for heavy-weight materials) utilizes a synchronized needle feed and feed dog system to advance multiple fabric plies concurrently. This synchronized feeding prevents layer slippage, eliminates seam puckering, and produces clean, balanced double-stitch lines on complex and demanding operations.

Powered by an integrated direct-drive servo-motor control system, the machine achieves over 40% energy savings while maintaining strong piercing force. It is equipped with an automatic semi-oil lubrication system featuring an external liquidometer gauge to monitor oil levels, along with an oil-regulating device that automatically cuts off supply when idle to prevent fabric contamination. Packed with smart production functions—such as automatic thread trimming, needle positioning, needle counting, auto reverse sewing, and quick needle gauge changes—it substantially boosts throughput in high-volume assembly lines.
