ABSTRACT:
Control means are provided for an apparatus for cross-winding packages of textile yarn or the like. The control means includes means operable during at least a portion of the rotation of the package at the selected rotational speed for increasing the relative frequency of traverse of the yarn guide means with respect to the selected rotational speed to a ratio less than the ratio of the rotational speed to the relative frequency of traverse prior to rotation at the selected rotational speed. The control means can gradually increase the relative frequency during operation at the selected rotational speed so that the ratio of the rotational speed to the relative frequency of traverse of the yarn guide means gradually decreases from the ratio of the rotational speed to the relative frequency of traverse at the beginning of rotation at the selected rotational speed.
