Abstract:
A device for winding a conical cross-wound bobbins comprisinga creel for receiving a conical bobbin and mounted for pivotal movement about a pivot axis, a yarn guide traversing along the creel for applying a yarn in cross-wound layers on the bobbin, a yarn accumulator movable relative to a travel path of the yarn for lengthening and shortening the yarn path, a first sensor device for determining and electronically signaling an instantaneous driven diameter of the bobbin, a second sensor device for detecting and electronically signaling an instantaneous point at which yarn is applied to the bobbin by sensing a position of the yarn guide, and a control device electronically connected to the first and second sensor devices for controlling the yarn accumulator in a defined manner as a function of the signal of the first and second sensor device, said function avoiding undesired changes in yarn tension in the yarn accumulator.
