Claim:
A process for winding a web substrate with a web rewinding apparatus, said process comprising the steps of: (a) providing a turret assembly comprising a plurality of mandrels extending parallel to a turret assembly central axis from said turret assembly, each of said mandrels having an unsupported end associated thereto; (b) providing a mandrel cupping assembly comprising a plurality of cupping arms for releasably engaging said unsupported ends of each of said plurality of mandrels, each of said plurality of cupping arms being cooperatively associated with one of said plurality of mandrels for releasably engaging said unsupported ends of said cooperatively associated mandrel; (c) providing a cupping spider having a hold-open cam track and a hold-closed cam track disposed radially and formed in a surface thereof; (d) cooperatively associating each of said plurality of cupping arms with a respective chuckling lever, each of said chucking levers providing connective engagement of each respective cupping arm with either of said hold-open cam track or said hold-closed cam track; (e) driving said turret assembly about a closed mandrel path about said turret assembly central axis; (f) indexibly rotating a first of said plurality of mandrels about said closed mandrel path to a first position; (g) connectively engaging a first of said plurality of cupping arms with an unsupported end of said first of said plurality of mandrels with a first actuator by disposing said respective chucking lever cooperatively associated with said first of said plurality of cupping arms from said hold-open cam track to said hold-closed cam track; (h) engaging a web substrate to said first of said plurality of mandrels; (i) disposing said web substrate about said first of said plurality of mandrels; (j) indexibly rotating said first of said plurality of mandrels about said closed mandrel path to a second position; (k) connectively disengaging said first of said plurality of cupping arms from said unsupported end of said first of said plurality of mandrels at said second position with a second actuator by disposing said respective chucking lever cooperatively associated with said first of said plurality of cupping arms from said hold-closed cam track to said hold-open cam track; and, (l) removing said convolutely wound web material from said first of said plurality of mandrels.
