Abstract
A wood-chipping machine (FIG. 1) has a plurality of cutters carried by a flywheel which is rotated to move the cutters across a throat through which material to be chipped is fed, and in which each cutter is substantially frust-conical and hence circular and a plurality of such cutters form a blade at a generally radial location of the flywheel. These facilitate blade replacement in the event of wear eg by adjusting the worn cutter angularly.
Claims1
A chip making machine having blades at a plurality of generally radial positions on a cutting disc characterized by each blade consisting of at least two circular cutters, so as to be angularly adjustable, whereby different portions of the periphery of each cutter may be successively moved into operation position, and wherein a series of two or more of said circular cutters is arranged along a line, all of the cutters in the series being in point-to-point contact one with the next, at least three cutters being arranged so that their axes lie on an arcuate line containing the center of the cutting disc.
