Abstract: A rotary slitter for container closures of varying sizes is disclosed. The embodiments include swivel housings to permit rapid changing of internal tools, and a rectilinear knife blade which eliminates adjustment problems normally occurring with curved knife blades.

Abstract: A waste stripping station for a machine for die-cutting plate-like workpieces includes a perforated board which is positioned between an upper movable tool and a lower movable tool for supporting a plate-like workpiece carried into the station by grippers. Waste bits of the workpiece are pinched between pins or elements of the upper and lower stripping tools and are carried vertically downward through perforations in the board. In order to provide clearance for the grippers, the perforated board is mounted to pivot around an upstream edge in order that its downstream edge may be lifted from a position allowing passage of the grippers to a position slightly lifting the plate-like workpiece.
