7 precision digital winding technology for slotless cylinder

At present, the winding of the winder is a way of using drum drive yarn. The winding of the yarn is decided by the curve on the grooved drum. Because the curve on the grooved drum is fixed, an overlapping problem is difficult to overcome.
