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.

Method for operating an automatic bobbin-winding machine during batch

An improved carrier for textile bobbins of the type having a disk-like base plate and a bobbin mounting pin upstanding therefrom of an outside diameter slightly smaller than the inside diameter of the tube of the bobbin to be supported and transported, wherein the pin is equipped with a frictional non-slip surface. As a result, if pointwise contact with the inside diameter of the tube occurs, e.g., by relative tilting of the tube, friction is brought to bear to counteract shifting of the tube on the pin. The invention is based on the recognition that in every situation in which relative motion between the bobbin and the carrier occurs, the bobbin becomes tilted on the carrier. The non-slip surface of the pin advantageously comprises an elastic surface, e.g., rubber or silicone. According to another aspect of the present invention, the pin diameter can be adapted to various inside diameters.
