  • Flexible real wood composition veneer
    Patent number: 6649245
    Abstract: A composition veneer that is extremely flexible, foldable and moldable, is provided by impregnating a wood veneer with a plastic film. The veneer has a smooth protective polymer surface without separate and distinguishable layers. As a result, the composition veneers of this invention exhibit moldability and shapeability properties similar to plastic sheeting, but contain natural wood and have the appearance of natural wood.

  • Wood surfaced foldable flexible sheet
    Patent number: 5194310
    Abstract: A sheet-like, foldable material is provided by laminating a very thin film-like veneer of material wood veneer to a thin backing material of paper or plastic by use of a bonding material which does not harden and can therefor be stretched and folded without causing rupture of the fibers of the wood veneer.

  • Machine for shear-slicing wood
    Patent number: 4019548
    Abstract: A machine is described for shearing a block of wood into a plurality of individual sheets in a single pass through a plurality of vertically and horizontally spaced, stationary shearing knives. The knives are rigidly supported, one after the other, in vertically spaced relationship. Means are provided to force the wood block past the knives. A pressure applicator is provided for positively holding the wood block down against a horizontal supporting surface as it passes through the shearing knives. 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.
