Clamping mandrel and stripping combination for a core sleeve of a rolled web, particularly a paper roll to supply a printing machine

Abstract From the Canadian patent

An ejector ring (18) surrounds an axially movable mandrel (6), on which a core sleeve or tube (19) for a paper web roll, for example a newsprint roll can be, supported. The ejector ring is resiliently supported on the holder structure, for example on a holder arm (1) and surrounds the mandrel, and is movable parallel to the mandrel. The structure is space-saving provides for secure retention, of the mandrel and is thereby capable of supporting heavy paper rolls, while providing for reliable stripping of core sleeves off the mandrel upon retraction of the mandrel into the holder structure, for example for exchange of a paper roll.
