Abstract
A feed roll for a log debarker or delimber wherein the roll is square-shaped in cross-section. Rows of gripping teeth are provided along each corner. The teeth are varied in height along the feed roll to form a sinusoidal or serpentine wave. Successive rows of teeth are offset so that the valleys of one row is aligned with the peaks of the succeeding row. The feed roll thus configured induces bouncing and side-to-side movement of a bundle of logs deposited thereon to induce spreading and side-by-side arrangement of the logs for processing.
