WD-7800-D4 Computerized special stitch pattern lockstitch sewing machine Characteristics:
1. Small bird's nest from sewing start, no thread coming off: The optimized cutter mechanism and digital thread tension gripper can make the length of the thread left on the needle short and stable, making the bird's nest significantly smaller when the second sewing starts , and does not come off the thread, achieving beautiful sewing quality without manual reprocessing.
2. Short thread ends: The optimized cutter mechanism and the beautiful sewing function (add a stitch of dense sewing before thread trimming), the thread length left on the cloth after thread trimming is less than 3MM.
3. High-quality reinforcement stitches, using a feeding mechanism controlled by a stepper motor, can achieve accurate feeding strokes, regardless of the size of the stitch length, can achieve stitch-overlapping stitching.
4. Using stepper motor drive technology: one motor completes the reverse sewing action. 5. Pattern sewing: controlled by stepper motor, can be set by yourself to produce D1-D9, 9 kinds of rice-shaped different stitches
