The feed roll (12) has contact elements to be brought against the tree trunk (10) to prevent the tree trunk slipping through. The roll has a base body (18) in the form of a wheel rim, to which springy flexible rod elements (30) are fitted to serve as the contact elements. They are arranged in rows in the axial direction of the roll. Their end sectors (32) are attached to the base body. They are spaced out radially round the base body.
