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.
