Anvil assembly for a slitting machine

An anvil assembly comprising:

• (a) a cylindrical core having a plurality of radially extending holes;
• (b) a plurality of anvil rings, each of which has an inner bearing surface and an outer cutting surface in rolling engagement with a cutter;
• and
• (c) means for resiliently supporting each anvil ring in spaced relationship about the core so that the anvil rings are radially moveable with respect to the core independently of one another, the support means including:
• (1) a plurality of support pins inserted into respective radially extending holes for supporting each anvil ring, said support pins being moveable between an extended position and a retracted position;
• and
• (2) means for resiliently biasing the support pins towards an extended position so as to engage the inner bearing surface of the anvil rings, wherein the support pins are moveable to a retracted position when a load is applied to the anvil rings.

An anvil assembly for a slitting machine having a cutter assembly including a plurality of axially spaced cutting disks for cutting sheet material into a plurality of strips, the anvil assembly comprising:

• (a) a generally cylindrical core having threaded end portions:
• (b) means for rotatably mounting the core to the slitting machine;
• (c) an axial bore extending axially through the core, said axial bore having at least one open end;
• (d) a plurality of radial holes extending from the outer circumference of the core to the axial bore;
• (e) a plurality of anvil rings disposed in spaced relationship about the core, each of the anvil rings including an outer cutting surface in rolling engagement with at least one of the cutting discs on the slitting machine and an inner bearing surface which is larger in diameter than the core so as to define an annular space between the anvil rings and core;
• (f) a pair of lock nuts for holding the anvil rings on the core, said lock nuts being threaded onto each end of the core so as to engage the outermost anvil rings;
• (g) means for resiliently supporting the anvil rings in spaced relationship to the core so as that the anvil rings are moveable radially with respect to the core, said support means including:
• 1. an elastic member inserted into the axial bore of the core;
• and
• 2. a plurality of support pins received in respective radial holes in the core such that one end thereof engages the elastic member and the opposite end projects outwardly from the core to engage the inner bearing surface of the anvil ring.
