ABSTRACT:
Apparatus for predeterminately sizing a core has a pair of generally opposed dies operable for compressing only an outer circumferential section of the core defined generally axially between a pair of opposite end faces of the core at least generally adjacent an outer circumferential surface thereof, respectively. Sizing jaws and a sizing arbor are operable for disposition in confronting and predetermined radially spaced apart relation with the outer circumferential surface and a plurality of tooth tip rows defining an inner circumferential surface of the core between the opposite end faces thereof, and the outer circumferential surface and the tooth tip rows of the core are displaced generally radially inwardly thereof into sizing engagement with the sizing jaws and sizing arbor thereby to effect the predetermined sizing of the inner and outer circumferential surfaces of the core in response to the compressing of only the outer circumferential section of the core by the opposed dies, respectively.
