Abstract
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.
