ABSTRACT:
An apparatus for breaking out, stripping or separating scrap pieces from a continuously moving sheet of material such as paper or cardboard having a die-cut or punched pattern therein is disclosed. The apparatus includes a pair of counter-rotating cylinder elements between which the sheet moves. At least one of such cylindrical elements, and preferably both, carry tool assemblies which are cam actuated and guided to cause the tool assemblies to move radially of the cylinders and grippingly engage or grasp even small scrap pieces. The tool assemblies further move such pieces, while firmly gripped, in a direction, usually downwardly, causing separation from the remainder of the sheet of material. The cylindrical elements and tool assemblies are formed for selective adjustment of the location of the tool assemblies over the width of the sheet and around the periphery of the cylinders.
