Abstract
A mandrel cupping assembly for releaseably enraging the ends of a plurality of mandrels supported on a web winding turret assembly is disclosed. The turret assembly provides a plurality of mandrels extending parallel to a turret assembly central axis and driven in a closed mandrel path about the turret assembly central axis. The mandrel cupping assembly provides a cupping arm cooperatively associated with each mandrel, a cupping arm support having a hold-open cam track and a hold-closed cam track disposed radially about a surface thereof, and a first actuator for disposing the cupping arm from the hold-open cam track to the hold-closed cam track. The cupping arm has a mandrel cup for releaseably engaging the end of a mandrel. Each cupping arm is carried in a radial path about the turret assembly central axis while disposed in either of the hold-open cam track or the hold-closed cam track.
