ABSTRACT:
An apparatus for trimming uneven edges from drawn and ironed metal bodies, such as cans, and breaking, knurling and discarding the scrap ring. The apparatus has oppositely rotating parallel shafts, one having an axially rigid supporting member, cutter and knurling roller at a free end on which a can is supported and the other having an axially rigid rotating wheel with a blade and knurling member peripherally mounted on adjacent sectors thereof. The blade cooperates with the edge of the cutter which is remote from the free end to trim the edge and the knurling member cooperates with the knurling roller. The members mounted on the first shaft and the teeth of the knurling member are configured to provide superior, relatively trouble-free operation.
