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.
