Abstract
The periphery of the chipping drum carries one or more axial rows of individual chipping bits in which the bits of adjacent rows are in staggered relationship if there is more than one row, and further carries an evening knife located in a position trailing the row or rows of individual cutting bits. The individual cutting bits are located with reference to ridges of the circumferentially corrugated drum periphery so that each ridge is disposed substantially centrally of a cutting bit. The anvil is corrugated complementally to the chipping drum periphery and is located so that the cutting edges of individual bits move through notches of the anvil. The evening knife moves close to the projections between the anvil notches.
