Patent ID: 7007886

Claim:
A winding spindle for mounting a plurality of yarn winding tubes on a yarn winding machine, comprising a rotatable inner tube connected for corotation to a drive shaft, an outer tube coaxially surrounding the inner tube in spaced relationship, with the inner tube and the outer tube being connected for corotation, a clamping device arranged between the inner tube and the outer tube and including a plurality of clamping elements positioned to extend through openings in the outer tube for engaging the interior of yarn winding tubes which are coaxially mounted on the spindle, a plurality of support members arranged between the inner tube and the outer tube in an axially spaced apart arrangement for producing a radially operative clamping force between the inner tube and the outer tube which is sufficient to increase the natural resonant frequency of the winding spindle, and wherein each support member is formed by a deformable support body and at least one clamping element which is in engagement with the support body, with the clamping force being producible by the interengagement of the support body and the clamping element.
