  • Flat-topped wave-board panel
    Patent number: 5290621
    Abstract: A flat-peaked and flat-troughed corrugated wafer board panel is provided. The panel is characterized in having a substantially uniform density.
    Type: Grant
    Filed: December 3, 1992
    Date of Patent: March 1, 1994
    Assignee: Her Majesty the Queen in right of Canada as represented by the Minister of Forestry

  • Process and apparatus for preparing a flat-topped wave-board panel
    Patent number: 5000673
    Abstract: A platen assembly is provided for manufacturing flat-topped wave-board. The assembly can be mechanically converted between a planar configuration and a wave-like configuration to form a board with a flat-topped and bottomed profile.
    Type: Grant
    Filed: April 24, 1989
    Date of Patent: March 19, 1991
    Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of Forestry
    Inventors: Lars Bach, Eduard Stark
  • Process for the manufacture of a corrugated wafer board panel
    Patent number: 4675138
    Abstract: A platen assembly is provided having a working surface which can be mechanically converted between planar and corrugated configurations. A mat of wood wafers coated with thermosetting resin binder is deposited between upper and lower, spaced apart platen assemblies of this type. The platen assemblies, in the planar configuration, are then pressed together to a limited extent to pre-compress the mat to fix the wafers. Horizontal force is then applied to the platen assemblies to convert them to the corrugated configuration, with the pre-compressed mat retained therebetween. The mat is therefore forced to adopt a corrugated form. The platen assemblies are then further pressed together and heated, to cure the resin and produce a corrugated wafer board panel.
    Type: Grant
