Abstract: A rotary, die cutting anvil system having a rotatable head with a cover mounted on the peripheral surface thereof. The cover includes inner and outer laminated layers. The outer layer is made of a generally tough resilient composition that is softer than the hard inner layer to which it is bonded. The inner layer has holes for receiving pins. The cover is mounted on the head by forcing the pins into the holes. The resilience and shape of the hard inner layer maintains the cover on the anvil until it is pryed off. The pins may be fixed to the anvil head or be fixed on rings or sleeves slidably mounted in grooves on the periphery of the anvil head to permit linear or oscillatory freewheeling.

Abstract: Rotary die cutting apparatus wherein the die blanket is mounted with respect to the anvil head such that both longitudinal and transverse relative movement is permitted between the die blanket and the anvil head during operation of the apparatus.

Abstract: The invention relates to a roller having a core with a channel formed in the surface which extends across the surface of the core. The channel is tapered in width from a first width adjacent a first edge to a second width adjacent a second opposite edge. A blanket is provided for covering the core with the blanket having a split element adapted to fit around the surface of the core and having first and second abutting edges. The blanket has first and second flanges depending from its abutting edges which flanges, when in abutting relationship, define a cross-sectional area substantially identical to the core channel.
