Product Introduction
1. The multi-functional combination switch is activated by a knee touch, enabling versatile settings such as stitch length adjustment, reverse stitching activation, presser foot lifting, and machine pausing—functions that simplify manual operation and significantly boost production efficiency.
2. The stitch length remains perfectly consistent when sewing both straight and curved seams; likewise, there is no variation in stitch length when stitching straight lines or inner arcs.
3. The machine uses three-synchronized feeding for reverse stitching, enhancing its ability to handle thick materials and steep inclines—making it especially ideal for sewing safety shoes, military boots, and snow boots.
4. Performance is 25% higher compared to traditional computer-controlled roving frames.
