METHODS AND APPARATUS FOR FABRICATING JOISTS, STUDS AND THE LIKE ABSTRACT OF THE DISCLOSURE Studs, joists, trusses and similar construction members having a pair of generally parallel chords and blocks disposed between the chords are manufactured by placing a plurality of blocks on a moving surface, with the blocks being spaced apart generally in a line along the direction of movement. A pair of chords are placed on each side of the line of blocks and are moved along with the blocks, The chords and blocks are moved past apparatus which drives fastening elements through the chords and into the blocks to secure the chords and blocks together in a rigid construction. Spacer lock plates may also be used to separate and lock the two chords in position, each spacer lock plate including opposed cuts on opposite edges thereof for receiving the chords, a stem portion between the cuts, and toothed flanges at each side of the stem portion. A chord is placed in each cut of each plate and then the chords and plates are moved through a first set of rollers to fold the flanges of the plates toward the chords to lie generally parallel with the axes of the chords. The chords and plates are then moved through a second set of rollers to press the flanges against and embed the flanged teeth in the chords.
