Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
Apparatus for the production of multigauge strip material comprising a tool holder assembly, said tool holder assembly including a horizontal member having speed vertical legs depending therefrom, a shaving tool having an elongated cutting edge, said shaving tool being located between said legs and being supported by said tool holder assembly, a base, an anvil having an arced surface supported on said base, said tool holder assembly being supported on said base and said shaving tool being located opposed to and adjacent the arced surface of said anvil, means for vertically adjusting and maintaining said tool holder assembly at a predetermined height to provide a desired shaving gap between the cutting edge of said shaving tool and the arced surface of said anvil, whereby a predetermined gauge of metal strip can be shaved from a thicker strip drawn between the anvil and the shaving tool.
Claim 2
Dependent Claim
145 words
