ABSTRACT:
The method and apparatus avoids ribbon windings when winding a cross-wound bobbin or cheese being driven by a drive drum having reversing thread grooves for yarn guidance and a drive mechanism having a course of motion. The circumferential speed of the drive drum is continuously varied. The cheese is accelerating and decelerating exclusively with the drive drum. The drive drum is accelerated and braked with the drive mechanism of the drive drum in accordance with a predeterminable periodic function. The cheese is rotated with a course of motion following the course of motion of the drive drum in a permanently phase-displaced manner.
