Abstract

The present invention relates to a feed roller (1) for use in feeding timber (6). Such a feed roller comprises a body (2) having disposed around its periphery (5) friction elements (4) for improving the engagement between the feed roller and the log. In the device of the invention the friction elements (4) are coupled together mechanically by coupling means (8, 10), the friction element on the surface of the log being arranged to guide the following friction element to the log at the right angle. Such mechanical coupling between the friction elements (4) efficiently prevents harvesting damages.
