ABSTRACT:
A device for removing the perforated guide edges from computer paper by a shearing action. The computer paper is supported on a support plate of a first frame, with the line of perforations substantially aligned with a shearing edge provided on the distal end of the support plate. A shearing mechanism is slidably mounted for vertical movement in a second frame which is secured to the top of the first frame. The shearing mechanism includes a shear plate which is movable downward for engagement with the computer paper along the line of perforations where application of an additional force to the shear plate results in clearly shearing the perforated edges from the computer paper. Springs bias the shear plate upwardly for another shearing operation.
