ABSTRACT:
An improvement in a debarking machine of the type including an annular frame, a plurality of debarking tools mounted in annularly spaced relation within the annular frame for rotation together about the axis of the annular frame and for movement toward and away from each other, infeed and outfeed mechanisms for feeding logs through the annular frame so that the tools will engage the exterior periphery of the successive logs and strip the bark therefrom during their movement through the annular frame. The infeed and outfeed mechanisms each include three driven spiked rolls arranged so that their spiked peripheries normally engage the exterior periphery of the log in centered relation and move the same axially through the annular frame for debarking by the tools. Each of the spiked rolls includes a cylinder and a multiplicity of spikes extending radially outward therefrom. The improvement comprises constructing each of the spikes in at least one of the rolls and preferably all so as to provide a radially outward cutting edge disposed generally within a plane parallel with the plane of the cylinder. Each cutting edge is configured to define at least one line extending transverse to the direction of movement thereof on the roll and a second line extending transverse to the first line. Each spike divergingly tapers from the lines in a direction toward the exterior of said cylinder.
