  • Publication number: 20080236349
    Abstract: A trim device for a lamination apparatus is provided. The lamination apparatus provides a cellulous based panel with at least one polymeric layer. The trim device includes a housing and a material removal apparatus at least partially disposed within the housing. The trim device also includes a pressure source in communication with the material removal apparatus. The pressure source is adapted to provide a pressure differential to the cellulous based panel having a waste section. The pressure differential positions the waste section into communication with the material removal apparatus so that the waste section is removed from the cellulous based panel during operation of the trim device.

  • Patent number: 7384497
    Abstract: A method for encapsulating a cellulose based substrate with polymeric film involves raising the temperature of the respective films using an electromagnetic radiation source and providing a pressure differential between an environment defined between the films and an environment external to the films so that conformance of the films to the cellulose based substrates is promoted. The cellulose based substrate is entirely encapsulated by the plastic films and the films are sealed around the peripheral edges of the cellulose based substrate as well as edges that are defined by slots and cutouts.

  • Patent number: 7247216
    Abstract: A method for encapsulating a cellulose based substrate with polymeric films involves heating the respective films using a non-electrogmagnetic radiation heating source and providing a pressure differential between an environment defined between the films and an environment external to the films so that conformance of the film to the cellulose based substrate is promoted. The cellulose based substrate is entirely encapsulated by the films and the films are sealed around the peripheral edges of the container as well as edges that are defined adjacent slots and cutouts.

  • Patent number: 6635141
    Abstract: The invention is a wane-free engineered wood product and the method of its manufacture. Lumber having wane along one or more edges is first milled to produce rectangular notches along each of the four edges. The notches are sized to remove all or most of the wane. The notched piece is then ripped lengthwise to produce two strips. These are rotated 180° and placed adjacently so that the notched edges face each other and form longitudinal channels. Strips of oriented strand board or a similar material are then affixed into the channels, preferably by gluing, reuniting then again into a unitary wane-free structural member.
