High Speed Needle Bar Feed Lockstitcher

The DY 0518-A is a high-speed industrial lockstitch sewing machine engineered for stable feeding, precision stitching, and long-term performance. It incorporates a link-type needle feed mechanism, link thread take-up, and rotary hook thread catching system to deliver consistent and high-quality lockstitch formation. The arm shaft and hook shaft are driven by bevel gears, ensuring smooth power transmission and reduced vibration even at high speeds.

Designed with a knob-type stitch length regulator and a lever-type reverse feeding mechanism, the machine allows easy adjustment and reliable back-tacking. The needle feed motion provides superior fabric control, preventing layer shifting and ensuring uniform stitch length when switching between high-speed and low-speed sewing or forward and reverse feeding.

The DY 0518-A is particularly suitable for silk, nylon, synthetic fabrics, and fine materials, making it ideal for garment factories focused on quality finishing. Equipped with an electronic servo motor, digital circuit control, and automatic sewing functions such as auto thread trimming, auto needle positioning, and auto stitch presetting, the machine delivers efficient, stable, and operator-friendly performance for modern production environments.
