Abstract

A cylindrical drum, which can turn in both directions, is fitted with outward-facing cutters which are fixed on removable slats uniformly spaced round the circumference of the drum; the centres of the cutters from parallel spirals round the drum. Pref. the cutters are uniformly spaced along slats and the spirals may run to the left and to the right, or they may all run the same way. The cutters are of a hard carburised alloy, pref. tungsten carbide. The cutters may be fastened in the slats by hard solder, or with a poured alloy, or by casting the slats round them. The slats are of dovetail section, fitted to the drum in pairs and held by wedges.
