APPARATUS FOR ROTATABLY SUPPORTING A HOLLOW, SUBSTANTIALLY CYLINDRICAL WINDING CORE, AND WINDING CORE FOR SUPPORTING A COIL OF FLEXIBLE, SUBSTANTIALLY FLAT PRODUCT S, ESPECIALLY PRINTED PRODUCTS

摘要

The rotatably mounted supporting arrangement (12) comprises two receiving claws (30) having V-shaped grooves (34). Lying diametrically opposite these receiving claws (30) are two clamping claws (32) which likewise have V-shaped grooves (34). The web-roll core (10) has on its inner side a circumferential flange (24) which is of V-shaped design. The flange (24) is supported in the grooves (34) of the receiving claws (30) and is pressed against the latter by means of the clamping claws (32). For the releasable clamping of the web-roll core (10), the clamping claws (32) can be moved from a rest position in which they do not lie against the core (10), into a working position in which, together with the receiving claws (30), they clamp the core (10). The core (10) with its roll (18) is clamped against the supporting arrangement (12) and mounted rotatably together with this. …IMAGE…
