  • Wire truss and apparatus for manufacturing a wire truss
    Patent number: 4079560
    Abstract: A wire matrix for a construction panel has a plurality of parallel longitudinal trusses, each truss having a pair of parallel longitudinal wire runners and a plurality of transverse wire struts in which the struts associated with one truss are all parallel to each other and extend diagonally between the parallel runners, with the struts in alternate ones of the trusses being parallel and the struts in adjacent trusses being skewed. The trusses are formed by making a grid of parallel longitudinal runners joined by diagonal cross wires which are then cut between adjacent pairs of runners to form separate trusses. The trusses are then joined by transverse wire runners forming a three-dimensional matrix.
