Abstract
The invention relates to a debarking shaft arrangement for a debarking machine ( ). A number of rotatable debarking shafts ( ) extending parallel to the advancing direction of the logs ( ) are provided with a number of teeth ( ) extending beyond the circumferential surface of the shaft ( ) and adapted to strip bark off the logs transversely to the lengthwise direction of the logs. The teeth ( ) are designed to be effective in both rotating directions of said rotatable debarking shafts ( ), and the debarking shafts ( ) 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.
