    Abstract: The invention concerns a barking tool for barking machines of the type having a plurality of swinging arms, each being at an inner end pivotally mounted on an annular rotator which is rotatable about an axis of rotation, and each having at a free outer end a processing edge. The processing edge is defined between a front and a top surface, which is adapted, during barking, to make an acute angle with the circumferential surface of the log. The barking tool further has a bead, which is located on the top surface in an area adjacent to the end of the processing edge furthest down in the feeding direction. The bead is essentially arcuate in such a manner that its height above the top surface successively increases from an area adjacent to the processing edge perpendicularly backwards therefrom and, more specifically, the height is adapted such that the bead during normal barking is positioned between a certain minimum and a certain maximum, and preferably essentially uniform, distance from the barked circumferential surface of the log independently of its diameter.

    Abstract: The invention relates to a debarking means for rotation ring type barking machines, and of the type comprising a plurality of swinging arms (1) yieldably engaging the circumference of an unbarked log and each formed at its free end with a seat (4) for a debarking means (2) detachably mounted by means of a bolt connection (3). The debarking means has a leading edge (7) serving as a cutting edge and a trailing support edge or surface (8) adapted to engage a shoulder (5) on the seat (4) to prevent turning of said debarking means relative to the arm. The support edge (8) extends obliquely in relation to the cutting edge (7), more particularly along the entire width of the debarking means and between two side edges of said means which are of different length.
