ABSTRACT:
The combination of a rotatable spindle and a bobbin receivable on the spindle for winding fibers on the bobbin. The spindle has an upper free end, and on this upper free end there is an elastically deformable drive for the bobbin, comprising a circular array of spaced resilient spring leaves. The bobbin is hollow and has on its interior a correspondingly spaced series of recesses that receive the spring leaves so that rotation of the spindle is transmitted to the bobbin via the spring leaves and recesses. The spring leaves are secured to the spindle at their lower ends and extend upwardly and radially outwardly from their lower ends and terminate in free ends that extend upwardly and radially inwardly relative to the axis of rotation of the spindle.
