Abstract
Abstract The apparatus includes a conveyor table having press heads mounted on opposite sides. Coils of connector plate stock having prepunched integrally extending teeth feed upper and lower press platens 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. Upon completion of the pressing operation, a feed mechanism locates predetermined lengths of connector stock 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 the frame being fabricated 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.
