ABSTRACT:
A method and apparatus for controlling a yarn winding machine, wherein a yarn is wound at a constant speed to a package on a driven winding spindle. A contact roll lies against the surface of the package. To enable an increasing package diameter, the center to center distance between the contact roll and the winding spindle is changed as a function of a variation in the rotational speed of the contact roll. To this end, the variation of the rotational speed of the contact roll is measured in each of a sequential series of predetermined time intervals T and converted into a control signal for changing the position of either the winding spindle or the contact roll.
