Abstract

A method and apparatus for winding a textile yarn into a cross-wound package is disclosed, in which the yarn is wound about the package at a substantially constant rate while the yarn is guided onto the package by a traversing guide. In order to avoid the formation of ribbons on the package, the traversing frequency of the yarn guide is periodically varied by shortening the stroke of the traversing yarn guide while maintaining an unchanged traversing speed of the traversing yarn guide. The avoidance of the formation of ribbons is also accomplished by varying the traversing speed of the traversing yarn guide during the times in which the traversing frequency of the traversing yarn guide is unchanged. Stops are provided for controlling the length of back-and-forth movement of the traversing yarn guide and the stops can be moved inwardly and outwardly to provide the required stroke modification of the traversing guide. Several specific embodiments of the yarn traversing apparatus are disclosed, and wherein the traversing apparatus includes gripper means mounted on a slide which is positioned between parallel runs of a drive belt, and control means for moving the gripper means to alternately engage the two runs of the belt and thus reciprocate the slide.
