Appl. No.:

13/272310

Inventors:

Jason William Day - Loveland OH, US
Fredrick Edward Lockwood - Cincinnati OH, US

International Classification:

B65H 19/30
B65H 19/22

US Classification:

2425334

Abstract:

A web rewinding apparatus comprising a turret winder and a mandrel cupping assembly is disclosed. The turret winder has a rotatably driven turret supporting a plurality of rotatably driven mandrels capable of engaging cores upon which a web material is convolutely wound thereabout. The mandrel cupping assembly has a plurality of cupping arms each cooperatively associated with one of the plurality of mandrels and having a mandrel cup for releaseably engaging the unsupported ends of the cooperatively associated mandrel. The mandrel cupping assembly has a cupping arm support having a hold-open cam track and a hold-closed cam track. Each cupping arm is carried in a radial path while disposed in either of the hold-open cam track or said hold-closed cam track. A first actuator disposes the cupping arm from the hold-open cam track to the hold-closed cam track.

Abstract:

A process for winding a web substrate is disclosed. The process provides the steps of: (a) providing a turret assembly having a plurality of mandrels each having an unsupported end; (b) providing a mandrel cupping assembly for releasably engaging the unsupported ends of each mandrel; (c) driving the turret assembly about a closed mandrel path; (d) indexibly rotating a first mandrel to a first position; (e) disposing a core upon the mandrel; (f) connectively engaging a first cupping arm with the unsupported end of the mandrel with an actuator; (g) engaging a web substrate to the core; (h) disposing the web substrate about the core; (i) indexibly rotating the mandrel to a second position; (j) disengaging the cupping arm from the mandrel at the second position; and, (k) removing the core and the convolutely wound web material from the mandrel.

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.
