Abstract

A yarn traversing apparatus which includes a pair of oppositely rotating blades for respectively moving the yarn in opposite directions along a main guide edge in a medial portion of the yarn traverse stroke. An auxiliary yarn guide is mounted in each of the ends of the traverse stroke. The main guide edge and the auxiliary guide edges extend through the traverse plane from opposite sides thereof, and they are configured so that the main guide edge guides the yarn and controls its speed along the medial portion of the stroke and the auxiliary yarn guides guide the yarn and controls its speed in the end regions of the stroke. The yarn tension thereby can be maintained substantially constant along the full length of the stroke.
