ABSTRACT:
An apparatus for breaking out 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. One of such cylindrical elements carries at least one tool assembly having a radially displaceable tool element. The cylindrical elements are further mounted at a distance from each other less than the combined radii thereof, including the tool element, and preferably with the tool carrying cylindrical element displaced toward the direction of advancement of the sheet during separation. The radially displaceable tool element cooperates with the remaining cylindrical element to grip scrap pieces on both sides thereof and effect a gripped displacement laterally of the remainder of the sheet to separate the scrap pieces. The location of the tool assembly can be varied over the width of the sheet and around the periphery of the cylindrical element.
