Abstract
A cutter for a rotary shredding machine which includes a disc-like body defining a coaxial shaft aperture therethrough adapted to accommodate a rotary shaft which defines a cutting axis, the body including a plurality of cutter body members and releasable fastening means for holding the body members together with at least one of the body members having a radially projecting tooth including a cutting edge along a leading edge thereof, each cutter body member having two first surface portions extending chordally from the body periphery and joined by a second surface portion adapted for engaging a shaft, the second surface portions together defining the shaft aperture, and each first surface being juxtaposed with, but spaced from, a parallel, corresponding first surface portion of the next adjacent body member thereby to permit limited tilting movement of the toothed body member circumferentially about the cutter axis with simultaneous momentary deformation of that body member when a sufficiently high impact force is applied to this tooth, the fastening means being constructed and arranged to permit such tilting.
