Abstract
A device for winding conical cross-wound bobbins has a creel pivotably mounted about a pivot axis and receiving the conical bobbin, a yarn guide traversing alongside the creel, and a yarn accumulator adapted to accumulate and pay-out a stored length of yarn. The prevailing instantaneous driven diameter (d ) of the cross-wound bobbin ( ) is detected by a first sensor device ( ′), the prevailing instantaneous position and/or the direction of travel of the yarn guide ( ) is detected by a second sensor device ( ′), and the sensor devices ( ′) are connected to a control device ( ) which supplies a control signal for a drive ( ) of the yarn accumulator ( ) as a function of the signals supplied.
