Apparatus for sectioning tire carcasses

An apparatus for cutting a reinforced matrix material comprising:

• a female die assembly comprising a plurality of regular geometric openings each defining sides and vertices thereof;
• a pointed vertical knife edge extending from each said side to a point above said female die;
• said vertices further defining a shearing means of said female die assembly;
• a reciprocating male punch assembly, of a shape having an interference, shearing fit through said female die assembly;
• a reciprocating, material clamping anvil assembly facing, opposed to said punch assembly;
• a first actuating means for activating said material anvil assembly against said punch assembly with a first pressure;
• said punch assembly and said anvil assembly clamping a matrix material with said first pressure;
• second actuating means for driving said punch assembly, said material, and said anvil assembly, clamped together with said first pressure, through said female die assembly.

A cutter for sectioning a reinforced flexible material into disposable pieces comprising:

• a female die having penetrating cutting means projecting forward of shearing means;
• male punch means cooperatively mating with said female die for shearing a material against said female die;
• and
• anvil means, facingly opposed to said male punch means, cooperatively engaged therewith for compressing a material to be cut against said male punch means during the activation of said male punch means through said female die.

An apparatus for sectioning a reinforced, flexible material of the type having a flexible matrix within which is embedded a knife edge resistant reinforcing means comprising:

• means for clamping said reinforced material to be sectioned, said means for clamping, driving said material against
• knife cutter means for piercingly cutting said matrix;
• and
• against shearing means for shearing said knife edge resistant reinforcing means;
• said knife cutter means and said shearing means further jointly comprise:
• a female die means having straight sides, the straight sides jointed at vertices thereof;
• said knife cutter means comprising pointed knife edges forming the straight sides of said die;
• said shearing means comprising hardened inserts forming the vertices of said die.
