  • Patent number: 4989487
    Abstract: The present invention is an anvil assembly for a slitting machine of the type including an arbor having a plurality of laterally spaced cutting disks mounted thereon. The anvil assembly is mounted to the slitting machine adjacent to the cutting discs. The anvil assembly includes a generally cylindrical core and a plurality of anvil rings which are concentrically disposed about the core under normal unloaded conditions. The anvil rings include an outer cutting surface which is in rolling contact with at least one of the cutting discs on the slitting machine. The anvil rings are resiliently supported in spaced relationship to the core so that when a load is applied to the anvil ring, the anvil ring will move radially with respect to the core independently of the other anvil rings. The resilient support means includes a plurality of support pins extending radially from the core member, and means for biasing the support pins into engagement with the inner bearing surface of the anvil rings.
