Abstract: A machine for cutting filing folders to provide identification tabs which includes the use of two rollers, a cutter roller and an anvil roller. The cutter roller has a plurality of surface cutters spaced circumferentially to cut identification tabs selectively at each end and centrally of a folder. The anvil roller has clearance areas, and also an anvil area which will cooperate with one of the surface cutters depending on the circumferential orientation of the cutter roller. The machine provides for a gear drive for the rollers and a mechanism for lifting and adjusting the orientation of the cutter roller to effect cutting of the file edges with one of the surface cutters.

Abstract: Upper and lower combined cutting and anvil rolls are provided with axially-extending circumferentially-spaced grooves for receiving compression cutting blades clamped therein, with their cutting edges substantially engaging the anvil portions of the other roll. One roll is drivingly connected to the other roll by intermeshing helical gears whereby one roll can be shifted axially and thereby simultaneously shifted circumferentially relatively to the other roll in order to vary the circumferential spacing of the cutting blades of the upper and lower rolls so as to vary the lengths of the sheets cut from a web of paper emerging from a printing press by which the pages have been printed. An adjusting screw shaft engages the upper roll through a thrust bearing and is equipped with a hand wheel and lock nut wheel to shift the roll axially and lock it in position. Registering concentric annular dials between the upper axially-adjustable roll and its helical drive gear indicate the adjustment which may be obtained.
