Description

Kingsew KS-GNDJ-1790A-K High-Speed Computer-Controlled Buttonholing Machine (Knitted Material)

High-speed computerized lockstitch buttonholing machine engineered specifically for processing delicate, stretchy, and elastic knit fabrics. The Kingsew KS-GNDJ-1790A-K utilizes an integrated direct-drive servo motor capable of reaching up to 4,200 rpm, paired with precision electronically controlled feeding to prevent puckering, stretching, or distorted buttonholes on flexible garments.

The machine incorporates a semi-dry / dry-head mechanism structure that eliminates oil staining on finished knitwear. Outfitted with an interactive LCD touchscreen interface with a USB port, it features a servo-motor-controlled cutter mechanism that supports multi-cut knife drops without the need to physically swap out the knife blade. An improved cooling system ensures smooth, continuous cycle operations across demanding high-output production lines.
