ABSTRACT:
Apparatus for producing machined timber from round timber logs comprises a eed device for receiving a log and feeding it longitudinally through at least one machining device whereby the middle region of the log is machined into squared timber. The wood sections lying outside the squared timber, on two mutually opposite sides of the round timber log, are separated into boards or planks during the feed movement of the log in its longitudinal direction, in a plurality of successive cutting operations. The machining device has a plurality of cutters staggered one behind the other, which cutters are combined into groups arranged in a frame which can be driven with an oscillating movement. A presser strip is associated with each cutter, and before each presser strip in the machining direction there is arranged a guide strip which contacts the outer surface of the log being machined.
