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.

Abstract: An inductively heated godet is mounted on a supporting frame which carries a rotatable drive shaft. A stationary primary winding is mounted about a magnetic core carried by a body which is fastened to the frame. A rotatable hollow shell which concentrically surrounds the primary winding is removably secured to the rotatable drive shaft.The magnetic core and rotatable hollow shell have in their longitudinal section essentially opposing L-shaped profiles with the flank portions thereof being concentric to the godet turning axis and the foot portion of each L-shaped profile extending substantially radially with respect to the godet turning axis toward the opposing flank portion of the other L-shaped profile such that the flank and foot portions of the shell and magnetic core form radially spaced annular gaps therebetween which are concentric to the godet turning axis.
