1. Small nest, not off: step driven tangential mechanism, with the optimized cutting tool mechanism, Ce make. the length of the thread left on the. needle short. and stable, so that when second sewing, the bird's nest will be significantly smaller, and will not take off, to achieve the beautiful sewing quality without manual reprocessing.

2. Short thread head: the optimized cutter mechanism and beautiful sewing function (add a stitch of tight seam before the tangent), the length of the thread head left on the cloth after the tangent is less than 3mm;

3. High quality reinforcement stitching: the feeding mechanism controlled by stepper motor can achieve accurate feeding stroke, and the reinforcing sewing with the coincidence of stitches can be realized regardless of the size of needle spacing.

4. Stepper motor drive technology: one motor can complete reverse seam movement.

5. Pattern sewing: controlled by stepper motor, it can produce D1-D9 and 9 kinds of rice grain lines.
