Abstract
A document shredder comprising the combination of a pair of counter-rotating rolls forming integral cutting discs interleaved with each other for cutting documents fed between the rolls into multiple strips, the discs also having cutting edges extending longitudinally of the rolls for cutting the multiple strips into short segments; multiple spacers mounted along the length of each roll, each of said spacers extending into the space between a pair of adjacent cutting discs on the same roll, and multiple diverters spaced along the length of each roll in register with the discs on the respective rolls, each of the diverters having an arcuate surface in closely spaced relationship to the radially outer surfaces of one of the discs for preventing the accumulation of the short segments of the cut documents adjacent the rolls.
