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. Each of the spiked rolls includes a cylinder and a multiplicity of spikes extending radially outwardly therefrom. The improvement comprises providing at least one of the infeed rolls with an elongated member (preferably three) secured to and extending substantially transversely across the exterior periphery of the cylinder thereof and defining a substantially continuous log penetrating surface disposed generally in the plane of the outer ends of said spikes. The log penetrating surface of each elongated member is configured to penetrate a log engaged thereby to an extent less than the penetration of the log by the spikes of the associated roll so that another roll cooperatively engaging the log serves to effect a transverse centering movement of the log along the elongated member while engaged thereby.
