ABSTRACT:
A rotary shear type shredder for shredding a wide range of materials, including flat and sheet materials has a plurality of spaced, intermeshed coacting cutter discs mounted for counterrotation on a parallel shaft. Each disc has a single cutter hook and a single rectangular cutter block fixedly mounted on opposite circumferential sides thereof. The hooks and blocks are arranged to form a spiral of cutters and hooks mounted on each shaft a 180 degrees apart and positioned so that blocks on one shaft feed material to hooks on the other shaft. The cutter blocks have a pair of right-angle cutter edges on both front and back sides for coacting with discs and hooks when rotated in a forward direction and coacting with cleaning fingers when reversed.
