Abstract
A shredder for shredding substrates has a shredder mechanism, a motor, and a pair of cooperating shredding structures each having a set of spaced apart cutter elements interleaving with one another such that substrates are fed between the interleaved sets of cutter elements. At least one of the cooperating shredding structures includes a rotatably mounted shaft rotatable by the motor with its cutter elements mounted in spaced apart relation with spaces therebetween. The shaft has a tubular body with an inner surface defining a hollow interior, an outer surface, and a plurality of openings formed through the tubular body open to the inner and outer surfaces. The openings are open to the spaces between the cutter elements on the shafts. A supply of lubricant communicates with the plurality of openings of the shaft to deliver the lubricant from the interior of the shaft to the cutter elements through the openings.
