Abstract: A core slabbing machine for the removal of paper wound on a mill roll core, to thereby permit reuse of the core. The machine includes a horizontal core-receiving mandrel and a carraige which moves horizontally back and forth above, and aligned with, the mandrel. The carriage carries a freely rotatable cutting wheel which is forced downwardly by a pneumatic cylinder onto the paper to be removed from a core. Each horizontal pass of the rotary cutting wheel cuts through a number of layers of paper determined by the force on the cutting wheel. This action is automatically controlled and continues until the cutting wheel reaches the core surface exterior after a number of cutting passes. The freely rotatable cutting wheel exerts a force on the core and paper substantially at right angles to the core and its supporting mandrel, thus obviating the need to anchor the core relative to the mandrel.

Abstract: The invention involves moving a strip of electroluminescent material past a shear in successive increments each equal to the length of a lamp outline to be cut from the strip. The shear is actuated after each incremental advance to cut a blank having a first dimension equal to the desired length of the lamp outline and a second dimension equal to the strip width, which is a multiple of the desired width of the lamp outline. The blank is then advanced past a punch and die in successive increments equal to the width of the lamp outline to be cut. The punch is actuated after each incremental advance to cut across or transverse to the second dimension to form lamp outlines having the desired length and width. The punch and die are configured to simultaneously cut a straight side of a lamp outline advanced past the punch and a straight side having a projecting electrical tab of an adjacent lamp outline behind the punch.

Abstract: A self-sharpening perforating punch head for perforating a web of plastic film is formed of one or more plates of a semirigid plastic resin, e.g. acetal homopolymer. The head has a row of tapered and beveled teeth which form a cutting edge at the back plane of the head. The cutting edge renews itself as the material wears by plastic-on-plastic abrasion. There are gaps provided at intervals among the teeth.

Abstract: Apparatus for cutting stacks of sheets has a first cutting machine which subdivides large piles of overlapping sheets into elongated strip-shaped stacks. The stacks are accumulated on a platform which is moved into a second cutting machine wherein a selected number of stacks is pushed by a feeding device across the cutting plane of a guillotine type knife before the knife descends to separate smaller stacks which come to rest on a plate or enter a gap formed in response to retraction of the plate so that the severed portions of the stacks can be advanced to a processing machine. The stacks which are about to be severed are pushed by a biasing device against a stop which extends at right angles to the cutting plane in the second machine, and each such stack is further pushed by an aligning device so that it abuts the feeding device. This ensures that the stacks are properly oriented prior to severing by the knife in the second machine.
