  • Method and apparatus for winding yarn into yarn package
    Patent number: 3931938
    Abstract: Yarn is continuously supplied at constant speed to a winding apparatus having a positively driven winding spindle. The tension of the yarn is periodically detected by a force transducer located at an edge of the area covered by the traverse motion of the yarn. The force transducer generates an electrical signal related to tension. The electrical signal is compared with a pre-set desired value and the difference is fed into a controller which acts upon a regulator for varying the speed of rotation of the winding spindle. The regulator varies the speed of rotation of the winding spindle according to the output of the controller, keeping the yarn tension at the desired value throughout the winding operation.
