ABSTRACT:
A method and apparatus for fabrication of unitary foam panels wherein frames members are fabricated by forming metal stock into a crossectional channel configuration, cutting and swedging the channel into predetermined lengths. The frame members are swedged to provide frictional interconnection at the corners thereof upon assembly of said frame members into a rectangular frame configuration. Assembly of the frame is accomplished in a shuttle having two assembly jigs. Upon assembly, each frame is moved by the shuttle into a molding press wherein a panel of foam is molded within the frame. The shuttle moves back and forth through the molding press in a manner which provides for removal of a completed panel and assembly of an additional frame from one jig of the shuttle while the molding operation is accomplished within the molding press upon a frame retained within the other jig of the shuttle.
