ABSTRACT:
A friction roller of a winding station of a winding machine is driven at a base angular velocity and is alternately accelerated and braked when the winding ratio is otherwise within a predetermined range of a selected whole number for causing slippage between the friction roller and a yarn package whereby the winding ratio is changed between values above and below the preselected range of the whole number. An evaluation device that calculates acceleration and braking values and a motor responsive to the evaluation device for driving the friction roller control the accelerating and decelerating of the friction roller when the winding ratio would otherwise be within the predetermined range of the selected whole number. Pattern windings of the yarn package are thus avoided.
