Abstract
Control means in an apparatus for cross-winding packages of textile yarn or the like is provided and includes means operable during at least a portion of the high speed or accelerating rotation for increasing the relative frequency of traverse of the traversing yarn guide means with respect to the rotational winding speed of the package from a frequency at which the ratio of the rotational winding speed to the relative frequency of traverse is greater than the ratio of the selected rotational winding speed and the related selected frequency of traverse. The control means can gradually increase the relative frequency during the high speed or accelerating rotation so that at least before the end of the high speed or accelerating rotation, the ratio of the rotational winding speed to the relative frequency of traverse of the yarn guide means is approximately the same as the ratio of the selected rotational winding speed and the related selected frequency.
