Abstract
An apparatus for rotatably mounting a web on a spool including two chucks, each carried by a shaft which is rotatably mounted in a mounting frame, and each having a mandrel axially delimited by a stop flange and on which the spool is releasably clamped. Each chuck has a stripping ring disposed around the mandrel between the stop flange and a spool to be received, and configured to be axially slidable therealong, and wherein the ring comprises an axially extending collar. An actuating device is mounted on the mounting frame and is coactive with the stripping ring to effect the axial displacement thereof away from the stop flange so as to strip the spool from the mandrel. The actuating device comprises a pressure member mounted for movement from a rest position to an operative position and having elements for grasping the collar of the ring at at least two points uniformly distributed over its periphery and pushing it away from the stop flange when in the operative position, and permitting the free rotation of the ring when in the rest position.
