<p>A shredding device uses a plurality of interleaving, counter-rotating discs (16,18) to reduce sheets of material into longitudinal strips. One or more notches (38), formed in the periphery of each disc, cut the longitudinal strips into segments. Deflectors (48,50) disposed in the spaces between each disc clear unwanted material from between the discs. When jammed, the rotation of the discs reverses, and the notches (38) bite into the jammed material to help remove it from between the discs.</p> |
