ABSTRACT:
A rotatably mounted support arrangement comprises two receiving claws having substantially V-shaped grooves. Diametrically opposite these receiving claws there are provided two clamping claws which also comprise substantially V-shaped grooves. A winding core comprises on the inner side thereof an annular rim or rib having a substantially V-shaped configuration. This annular rim or rib is supported in the grooves of the receiving claws and is pressed against the latter by means of the clamping claws. For releasably clamping the winding core, the clamping claws can be brought from an idle or ineffectual position, in which the clamping claws do not bear against the winding core, into an operative or effectual position in which the clamping claws clamp or fixedly hold the winding core together with the receiving claws. The winding core with the product core or wound package thereof is clamped at the supporting arrangement and rotatably supported conjointly with the latter.
