Abstract

A yarn traversing apparatus is disclosed, which is adapted for use in winding a running yarn to form a cross wound package. The traversing apparatus includes a yarn guide bar, and a pair of oppositely rotating rotors, and the rotors include radiating arms which define two closely adjacent planes of rotation. The rotors are mounted for rotation about offset axes, so that the arms sweep across the guide bar in opposite directions to define the yarn traverse stroke. The rotors are rotatably driven by a gear drive system which includes a transmission shaft, and the transmission shaft and one of the rotors are mounted in eccentric bushings which permit the meshing gears to be adjusted so as to eliminate backlash.
