Yarn winding apparatus comprises means for supplying yarn at a constant speed, a winder having a yarn traverser and a fixed guide acting as a pivot for the traverse motion of the yarn. The apparatus includes a force transducer for generating an electrical signal indicating yarn tension, a rotary pulsing guide for periodically deflecting the yarn to bring it into contact with the force transducer, a setting device for generating an electrical signal indicating a predetermined desired value of yarn tension, a comparator for producing an error signal indicating the difference between the force transducer electrical signal and the setting device electrical signal, and a regulator for regulating the speed of rotation of the winding spindle in response to the difference between the foregoing signals.
