ABSTRACT:
This invention relates to a device for regulating the winding speed in the formation of cross-wound conical bobbins where the yarn is withdrawn at constant speed from a rotor spinning unit by a lever system able to displace the friction drive band of the drive roller for the conical bobbin under formation, in order to vary the average resultant value of the varying winding speed during each double stroke of the yarn guide element. Said lever system is operated by a two-direction rotary drive source which is activated when a linear position element, associated rigidly with the yarn storage element, senses by known means that abnormal storage swings persist.
