ABSTRACT:
A method and apparatus for winding textile yarns into packages are provided in which the formation of undesirable patterns in the windings of yarn is completely avoided. According to this invention, any one of the variable parameters of traverse motion speed, such as time intervals between reversals from acceleration to deceleration or vice versa, traverse motion speed attained between such reversals or changes, or rates of acceleration or deceleration, is varied aperiodically, and the control of such speed changes may be accomplished digitally or analogically in response to a random number sequence.
