ABSTRACT:
An improvement to a dual arbor scrap chopper used for cutting scrap edge trims associated with flat sheet metal strip production. The scrap chopper utilizes a pair of rotary arbors, each having identical angularly displaced multiple sided blades aligned for progressive cutting registration with each other as the arbor rotates. Each of the blades are defined as a symetrical multi-sided configuration allowing each blade to contain multiple usable cutting edges which can be exposed upon inversion, inverting or rotation of the blade selectively in its respective rotary arbor.
