Abstract
A spindle intended to support on the inside thereof and drive in rotation at least one winding support for winding textile yarns. The spindle has at least one gripping element made up of at least two flyweights, able to come in contact with the inside surface of the winding support and develop, under the effect of centrifugal force, a radial thrust assuring its gripping. It applies to winding of textile yarns, particularly chemical yarns, at high speeds of 3,000 to 7,000 m/min and more.
