Spinning machine having yarn carriers retained in pairs on a revolver

Abstract

A spinning machine for ring, hopper or cap spinning with a revolver, yarn carriers retained in pairs on the revolver, and a ring traveler, hopper or cap system with a spinning ring, hopper or cap for the yarn carriers. One yarn carrier of a pair of yarn carriers having a finished cop in a spinning position is released from a ring traveler, hopper or cap system after the end of a spinning cycle. The finished cop is rotated through 180.degree. about the axis of the revolver for moving the one yarn carrier of the pair of yarn carriers to a doffing position while moving the other yarn carrier of the pair of yarn carriers to the spinning position and spinning yarn onto the other yarn carrier. The ring traveler, hopper or cap system is mounted on the other yarn carrier once the spinning position is reached. Yarn travel from the one yarn carrier in the doffing position to the spinning ring, hopper or cap is maintained. The yarn in the vicinity of the bottom end of the yarn carrier is moved approximately radially toward the axis of the yarn carrier into an approach position. The yarn is grasped in the approach position with the yarn carrier being set into rotation. The yarn is carried along about the yarn carrier for piecing.
