ABSTRACT:
A V-shaped, substantially flat, sheet metal, combined web-connector plate having diverging web-forming legs and integral apex and leg end connector portions provided with struck-out teeth for embedding within spaced apart wooden chord members to form a wood chord-metal web type truss. The truss is assembled upon an apparatus including a horizontal support surface, chord support means for removably positioning the chords above the support surface and means for positioning a number of truss-web connectors beneath the chords, with their teeth extending upwardly towards the chords. Additional web-connectors are located loosely upon the upper surfaces of the chords. A two-unit press is supported upon the support surface on opposite sides of the chords for movement parallel to the chords, and is provided with clamp pressure means which overlap selected apex and leg connector portions on both chords and simultaneously squeeze them toward the chords for embedding their teeth therein. Thus, the finished truss formed on such apparatus is provided with horizontal parallel chords with numerous vertically arranged metal webs located on opposite vertical sides of the chords and secured only to the side faces of the chords by the embedded teeth.
