This machine is a new generation of intelligent computer flat sewing machine. It adopts the head design of oil-free wire pole and rod needle to avoid the seam pollution caused by oil pollution.Equipped with automatic sensing seam thickness detection device, automatic feeding compensation when sewing steps, effectively reduce the change of needle spacing.The tension of the surface line is controlled by the electromagnet, and the system can automatically adjust the tension of the line according to the change of the thickness of the sewing material.The tangential mechanism is driven by stepping motor, with simple structure and super short thread head.
