Abstract

A tensioning device for hubs, comprising a winding shaft having rotatably and drivably mounted on it individual winding elements as hub holder for hubs with inner cylindrical bores, the tensioning device including measures for locking the hubs in the axial direction on each individual winding element, wherein the hub (1) includes along its inner circumference (3), alongside the inner bore (5) and uniformly distributed over the circumference, a multiplicity of resilient elements (2), which have the form of a bent-off arm which extends in the radial direction from the inner circumference (3) of the hub (1) and is bent off in the circumferential direction, the end (4) of each resilient arm being at a distance from the bending point of the next-following arm.
