摘要

A shredder having a stationary comb cutter and primary and secondary cutters on the rotor providing "punch and die" shearing action suitable for shredding wallboard or the like. Means for metering the incoming feed through a pair of nip rollers, the upper set of which is spaced inboard such that they do not press on the side edges of the wallboard as it passes through the nip.
