Description

Kingsew KS-GNDJ-20U Series Industrial Zigzag & Straight Stitch Sewing Machine

Versatile medium-speed industrial lockstitch zigzag and straight stitch machine designed for tailoring, embroidery, decorative edge stitching, and garment assembly on light- to medium-heavy fabrics. Built on the classic 20U platform, the machine utilizes an adjustable needle position and bight mechanism paired with a smooth drop-feed system, allowing operators to transition between standard straight seams, wide zigzag stitching, and freehand embroidery without changing setup.

Its heavy-duty cast-iron body houses a horizontal rotary hook system that delivers balanced thread tension at elevated speeds. Outfitted with an easy-to-use knee lifter that doubles as a stitch-width control for artistic tapering and monogramming, it provides precise manual control over decorative motifs, button attaching, and reinforcement sewing.
