Abstract
A winding machine has winding stations and a transport path for leading cops to the winding stations. An apparatus for loosening a reserve yarn winding from peripheries of the cops disposed at the transport path includes scissors having two legs being open at an onset of a yarn search. One of the legs is a yarn loosener to be placed against a cop positioned on the transport path. The cop is rotated to bring the yarn loosener under the reserve yarn winding. An actuator closes the scissors after a predetermined search period. The apparatus for loosening the reserve yarn winding may include a yarn loosener to be placed at a cop positioned on the transport path, wherein the yarn loosener has a forward edge for picking up a yarn, and a sharp cutting edge with a height being increased at increasing distances from the forward edge for cutting the yarn.
