Abstract
The invention relates to a debarking shaft arrangement for a debarking machine (1). A number of rotatable debarking shafts (3) extending parallel to the advancing direction of the logs (2) are provided with a number of teeth (4) extending beyond the circumferential surface of the shaft (3) and adapted to strip bark off the logs transversely to the lengthwise direction of the logs. The teeth (4) are designed to be effective in both rotating directions of said rotatable debarking shafts (3), and the debarking shafts (3) are designed to be reversibly mounted in the debarking machine. Reversible debarking shafts equipped with bi-directionally effective teeth permit renewal of worn teeth on a debarking shaft by reversing the orientation of the shaft relative to the debarking machine.
