Abstract

The round pieces of wood are laterally flattened at least on the curvature plane and are conveyed in a straight line parallel with the curvature plane. After the round wood pieces have been measured, a bow line (80) of the curvature is taken. The round wood pieces are machined by first tools while moving crosswise to the direction of travel and while turning on an axis at right angles to the curvature plane and following the bow line. Forward thrust and or guide elements (68-78) guide the wood along the bow line. The timber is machined by second machining tools (82,84). An independent claim is also included for the system using the method.
