Abstract
A shredding device uses a plurality of interleaving, counter-rotating discs to reduce sheets of material into longitudinal strips. One or more parallelogram or diverging configured notches, formed in the periphery of each disc, cut the longitudinal strips into segments. Deflectors disposed in the spaces between each disc clear unwanted material from between the discs.
