Abstract

A mandrel cupping assembly for releaseably engaging the unsupported ends of a plurality of mandrels disposed on a web winding turret assembly is disclosed. The mandrel cupping assembly comprises a cupping arm turret, a mandrel cup and cupping arm cooperatively associated with each mandrel, an outer ring guide disposed coaxially about the cupping arm turret, and an actuator cooperatively associated with each cupping arms. Each of the mandrel cups and cupping arms are disposed radially about the cupping arm turret. The mandrel cups releaseably engage the unsupported end of the mandrel against the outer ring guide. The mandrel cups have a hold-open position and a hold-closed position and are carried in a radial orbital path about the cupping arm turret while disposed in either of the hold-open position or the hold-closed position. Each actuator disposes the corresponding cupping arm from the hold-open position to the hold-closed position.

Dependent claims

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 arm turret having a cupping arm turret central axis;
a mandrel cup and cupping arm cooperatively associated with each mandrel of said plurality of mandrels, each of said mandrel cups and cupping arms being disposed radially about said cupping arm turret;
an outer ring guide disposed coaxially about said cupping arm turret;
wherein each of said mandrel cups releaseably engages said unsupported end of said mandrel against said outer ring guide, 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 arm turret central axis while disposed in either of said hold-open position or said hold-closed position;
and,
an actuator cooperatively associated with each of said cupping arms, each of said actuators being capable of disposing said cupping arm cooperatively associated thereto from said hold-open position to said hold-closed position.
