Abstract: An apparatus for producing squared timbers by means of severing portions or boards from opposite surfaces of the log without creating either chips or sawdust characterized by oscillatory opposed banks of staggered blade units with the blades of each unit extending progressively toward the axis of the log as the log passes therebetween. To provide improved surface quality of the boards produced, the apparatus has one of the banks of blades rigidly mounted in a first adjustable carriage and the other bank is mounted in a subframe movable in a second adjustable carriage with the subframe and other bank being urged into engagement with the log under a predetermined contact.

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.

Abstract: A method and apparatus for processing round logs in which substantially the entire log is utilized to produce a relatively high value wood stock. The outer area of the log is peeled in sheets to square the central area for the formation of planks, beams, boards or the like while the peeled sheets may be dried, graded, cut to size and joined together and glued to form strips of any desired length and width which, in turn, may be glued in layers to form panels or other high value components. A plurality of powered, adjustable peeling knives are arranged in opposed sets to machine the log as it is caused to pass thereby on a conveyor. In one form of the invention the knives are driven to undergo a circular oscillatory motion while a second embodiment discloses a knife drive in which the knives are guided in vibratory movement. A third form of drive permits a drawcut in that the peeling knives are drive in a longitudinal direction relative to their cutting edges.
