Abstract

A method of handling the tube and cop supporting pallets in a textile winder during batch changing operations, by which, at the end of a batch, the pallets are maintained in the transport system of the winder and are conveyed from the tube return path to the cop supply path. First, the winding operation is stopped, a selected winding station at one end of the distribution segment is evacuated to facilitate clearing therethrough of the distribution segment and, subsequently, the other winding stations are successively evacuated to release the pallets held in their respective unwinding and backup positions. Downstream along the tube return path, the cops or tubes are removed from all approaching pallets, regardless of whether they still carry any yarn. The resulting empty pallets are guided from the cop supply path around the end of the bobbin-winding machine, accumulated at the upstream end of the tube return path, and released only after they can no longer interfere with the successive evacuation of the pallets from the winding stations onto the tube return path.
