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 mechanism includes three driven infeed 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.
