ABSTRACT:
The apparatus includes a conveyor table having pairs of press heads mounted on its opposite sides. Strips of sheet metal stock from coils are fed through respective die sets for punching integrally extending teeth in the metal strips and the connector plate stock thus formed is fed into the respective paths of movement of upper and lower press platens. The platens are movable toward one another to substantially simultaneously cut the connector stock to predetermined lengths to form connector plates and embed the teeth of the connector plates on opposite sides of joints formed by wooden frame members disposed on the conveyor between the press heads. Simultaneously with the pressing operation, the die set punches additional teeth into the strip. Upon completion of the pressing operation, a feed mechanism locates predetermined lengths of connector stock with struck teeth between the press platens for the next cut and embedment operation. Selectively extensible and retractable stops are provided on the conveyor table and press heads against which respective webs and chords of a frame undergoing fabrication are butted to locate the same in position forming a completed frame. Clamps on the conveyor press the chords against the web ends while the connector plates are embedded in the joints.
