ABSTRACT:
An improved apparatus for and a method of trimming an outwardly directed flange at the end of a metal container body and severing the ring of scrap removed employs two substantially semicircular concave cutters supported for rotation about spaced parallel axes disposed substantially in the plane of the flange to be trimmed and driven for rotation about their respective axes to engage the flange substantially simultaneously to sever the scrap ring around substantially the entire periphery of the container. The ring of scrap is cut into four pieces either by initially die-cutting or otherwise removing segments from opposed sides of the flange tangent to the trim line prior to engagement by the rotating arcuate cutters or alternatively, the arcuate cutters may sever the scrap as a complete ring and sever the ring into pieces upon continued movement in their arcuate paths past a stationary clipper block spaced below the container flange. The container is preferably trimmed with the open end facing downward, with the arcuate cutters rotated to propel the trimmed scrap downward for easy removal without interfering with operation of the apparatus or feed of the containers.
