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.

A method for joining a pair of wooden members by applying a sheet metal connector plate, of the type having integrally struck teeth projecting from one side thereof, to the wooden members at their juncture comprising the steps of: providing a coil of connector stock of the type having integrally struck teeth projecting from one side thereof, feeding the connector stock from the coil into the path of movement of a presshead carrying a cutting edge thereby defining relative to the cutting edge a predetermined line of cut along the connector stock, providing a reaction surface cooperable with the cutting edge and comprised of a plurality of tines defining a plurality of laterally spaced recesses; guiding the teeth of the stock along the recesses as the stock is fed into the path of movement of the presshead; displacing the presshead to engage the cutting edge and reaction surface tines along opposite sides of the stock and along its predetermined line of cut and, upon continued displacement of the presshead, cutting the stock to form a connector plate of predetermined length, and pressing the teeth of the connector plate thus formed into one side of the adjoining wooden members upon continued displacement of the presshead in the same stroke thereof.
