ABSTRACT:
A tool for rotation ring type barking machines comprises a curved swinging arm which is adapted to carry at a first, free end a cutting edge and which is detachably connected at its opposite end by means of a screw connection with a shaft rotatably mounted in the rotor of the machine, more particularly via a holder which is preferably made in one piece with the shaft and extends at an angle relative to said shaft. The swinging arm is displaceably movable relative to the holder and fixable by means of said screw connection in different selectable positions relative thereto, in order to permit variation of the distance between the center of the pivot shaft and the center of gravity of the swinging arm.
