1. A mandrel cupping assembly for releaseably engaging unsupported ends of a plurality of mandrels disposed on a web winding turret assembly having a web winding turret assembly axis, each of said plurality of mandrels extending generally parallel to said web winding turret assembly axis, each of said mandrels being driven in a closed mandrel path about said web winding turret assembly axis, said mandrel cupping assembly comprising:
a cupping spider having a cupping spider axis; a mandrel cup cooperatively associated with each mandrel of said plurality of mandrels, each of said mandrel cups being disposed radially about said cupping spider, each of said mandrel cups comprising a pair of cupping arms configured as a first-class double-lever with a pivot acting as a fulcrum; wherein each of said mandrel cups releaseably engages said unsupported end of said mandrel, each of said mandrel cups having a hold-open position and a hold-closed position, each of said mandrel cups being carried in a radial orbital path about said cupping spider axis while disposed in either of said hold-open position or said hold-closed position; a first actuator for disposing said cupping arms from said hold-open position to said hold-closed position; and, a second actuator for disposing said cupping arms from said hold-closed position to said hold-open position.
