  • Machine and method for fabricating structural wood components
    Patent number: 6823577
    Abstract: A machine and a method for fabricating structural wood components, such as joist building components, is described. The machine comprises a component assembling jig for assembling pre-cut wood pieces at predetermined positions corresponding to a structural wood component design. Magnetic elements are adapted to position connector plates at predetermined locations in the machine. The assembled wood pieces of the jig are displaced to a transfer platform where they are clamped with the wood pieces positioned at interconnecting junctions. The transfer platform then displaces the assembled and held wood pieces to a position adjacent magnetic connector plate applicators whereby the plates are secured to the wood pieces at the interconnecting junctions to interconnect the wood pieces together to form an assembled structural component which is then displaced and discharged from the machine.
