Mandrel cupping assembly

摘要

A mandrel cupping assembly for releaseably engaging the unsupported ends of a plurality of mandrels supported on a web winding turret assembly is disclosed. Each of the mandrels is driven in a closed mandrel path about a web winding turret assembly axis. The mandrel cupping assembly has a cupping arm turret with a cupping arm turret central axis, a cupping arm cooperatively associated with each mandrel of the plurality of mandrels, and a first actuator for disposing the cupping arm from a hold-open position to a hold-closed position. Each of the cupping arms is disposed radially about the cupping arm turret and is carried in a radial orbital path about the cupping arm turret central axis while disposed in either of the hold-open position or the hold-closed position.

主权项

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 arm turret having a cupping arm turret central axis; a cupping arm cooperatively associated with each mandrel of said plurality of mandrels, each of said cupping arms being disposed radially about said cupping arm turret within a track formed in a surface of said cupping arm turret and being capable of releaseably engaging said unsupported end of said mandrel, each of said cupping arms having a hold-open position and a hold-closed position, each cupping arm being carried in a radial orbital path about said cupping arm turret central axis while disposed within said track in either of said hold-open position or said hold-closed position; and, a first actuator for disposing said cupping arm from said hold-open position to said hold-closed position.
