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.

The wood block contacting surface of the pressure applicator is made up of a plurality of small diameter rod-like roller elements, each supported so that it can individually rotate with respect to adjacent roller elements. The roller elements contact each other and each is individually pressed against the wood block by a block-like mass of polyurethane elastomer of a durometer such that high unit pressure is maintained between each of the roller elements and the wood block.

Abstract: A wood slicing apparatus for slicing of slats, strips or similar elements from board-shaped base material, with minimum wastage and noise, and maintenance of plane cut surfaces. Boards are initially placed in a loading station from which the topmost board is automatically transferred to a cutting station whereat slats are cut from the board by a cutting unit carrying rigidly held thin cutting blades. The slats are subsequently transferred through smoothing and squaring-off means which apply pressure to smooth both pairs of opposite sides of each slat, during which time the cutting unit is returned to its initial position and the board is advanced to permit severing of further slats therefrom, this action being repeated until there is insufficient board material for removal of further slats, whereupon the apparatus is automatically stopped.
