A pair of chipping wheels mounted on a common drive shaft have blades on their outer, plane working surfaces, the blades on one wheel being for chipping veneer material and the blades on the other wheel being for chipping core material. The blades extend across a major proportion of the radii of the wheels, and feed means are arranged to feed veneer and core material to the associated wheels across substantially the full radial length of the blades. The veneer material is fed to its wheel substantially perpendicular thereto and the core material is fed to its wheel at an acute included angle thereto.
