This machine adopts a new type of rotating thread picking rod, which can obtain high-quality and stable thread traces even under polar tension. The shuttle shaft is used in conjunction with a compensation mechanism, ensuring that the left and right positions of the rotary shuttle are equal when hooking the wire, which can prevent jumpers and wire breakage. For fabrics with stretchability, equipping a small amount of lifting and pressing foot device will make the pressing foot gently float, and then sewing will produce neat and beautiful stitches. Specially designed winding device, which is faster and more convenient to use.
