13 The present invention relates to a processing means for barking machines of the type having a plurality of swinging arms (11), each being at an inner end pivotally mounted on a rotatable, annular rotator, while at an opposite outer free end, they carry such a processing means and are actuated by a spring load which strives to pivot the outer end inwards to the axis of rotation of the rotator. The processing means comprises a front (1), a rear (2), an upper (3) and a lower (4) surface, which are designed in such manner that an edge serving as a processing edge is defined between the front (1) and the upper (3) surface. The lower surface (4) is formed with an engaging means (8) which is adapted to engage a matching formation (14) in a seat (12) in the outer end of the swinging arm. The rear surface (2) acts as a supporting surface which serves to abut against a corresponding swinging arm supporting surface (16) which is directed forwards or obliquely forwards against the direction of feed of the logs. The engaging means comprises a ridge (8) or a groove and is rectilinear and elongate in such manner that its total length exceeds its height or depth, and preferably also its width, at least by a factor ten. The engaging means (8) further extends at an acute angle of at least 10.degree. in relation to the rear surface (2).
