  • Method of making laminated wood beams with varying lamination thickness throughout the thickness of the beam
    Patent number: 7141137
    Abstract: A method of forming a laminated beam includes assembling a plurality of individual wood laminations in a juxtaposed relationship, and joining the assembled laminations together to form a laminated beam. The assembled laminations define a tension zone of individual wood laminations, a core zone of individual wood laminations, and an compression zone of individual wood laminations. The average thickness of the laminations in the tension zone is less than the average thickness of the laminations in the core zone, and the average thickness of the laminations in the compression zone is less than the average thickness of the laminations in the core zone.
