  • Flat oriented strand board-fiberboard composite structure and method of making the same
    Patent number: 5718786
    Abstract: An oriented strand board (OSB)-fiberboard composite structure is comprised of a baseboard having three wood strand layers, the wood strands being oriented in space with respect to a board forming machine such that a core layer is comprised of wood strands oriented generally in a random or cross-machine direction and each adjacent layer is comprised of coarse and fine wood strands oriented generally in the machine direction. In a preferred embodiment, the wood strands comprising each adjacent OSB layer are formed with the coarsest strands located nearest the core layer and the finest strands are located nearest the outer surfaces of each outer board layer. The OSB-fiberboard composite product is clad with a wood fiber overlay on one major surface of the baseboard. The composite board is manufactured without warping, by providing particular OSB layer thicknesses, such that the lower OSB layer is about 25% to about 35% thicker than the OSB layer bonded to the fiberboard.

  • Oriented strand board-fiberboard composite structure and method of making the same
    Patent number: 5525394
    Abstract: An oriented strand board product is provided. The board is comprised of a baseboard having three wood strand layers, the wood strands being oriented in space with respect to a board-forming machine such that a core layer is comprised of wood strands oriented generally in a random or cross-machine direction and each adjacent layer is comprised of coarse and fine wood strands oriented generally in the machine direction and wherein the wood strands comprising each adjacent layer are formed with the coarsest strands located nearest the core layer and the finest strands are located nearest the outer surfaces of each outer board layer. The OSB board product is clad with a dry felted wood fiber overlay on one planar surface of the baseboard.
