OPEN-END TYPE OF SPINNING APPARATUS WITH IMPROVED DEVICE FOR LOADING A NEW TUBE IN THE DOFFING CYCLE AND METHOD FOR LOADING A NEW TUBE IN THE DOFFING CYCLE OF THE OPEN-END TYPE SPINNING APPARATUS

摘要

A spinning apparatus comprising at least one spinning head having a spinning unit and a reel winding unit, wherein the reel winding unit wraps a reel of yarn obtained from the underlying spinning unit on a tube, a tube-holder basket housing a plurality of tubes on which the yarn is wound, a doffing tray positionable on the spinning unit and provided with devices for picking up and transporting a tube from the tube-holder basket to a pair of tailstocks on the reel winding unit. The doffing tray comprises a tube separator device having a support arm which supports two blades, movable, so as to intercept a number of tubes contained in the tube-holder basket and to separate them at least partially from a tube destined to be grasped by the pick-up and transport device and placed between the tailstocks. Advantageously, the tube separator device and the pick-up and transport device are mechanically independent of each other, so that they may be operated separately from each other.
