Yarn winding apparatus and method

摘要

The present yarn winding apparatus and method includes a yarn traversing mechanism, a pair of rotatably supported winding spindles, spaced apart main and auxiliary contact rolls, and a rotatable turret supporting said winding spindles in opposed relationship thereon. The turret rotates the winding spindles for successive movement into an operational position where one of the winding spindles is in engagement with the main contact roll and the other winding spindle is positioned out of engagement with both rolls and in position for yarn packages to be doffed therefrom. The turret also rotates the winding spindles into a yarn transfer position at which the winding spindle with full yarn packages thereon is in engagement with the auxiliary contact roll so that the yarn may be transferred from the full yarn packages to the empty tubes on the other winding spindle. In one embodiment, the spindles are rotatably driven by the contact rolls, and in another embodiment the contact rolls monitor the winding speed of the spindles and the spindles are rotatably driven by separate drive motors.
