Abstract:
A wire frame reinforcing fabrication for incorporation into a sifting screen support frame, constructed from resistance welded steel wire matrices arranged in two parallel spaced apart planes and themselves welded together along at least two edge regions by welds between protruding ends of the wires of the two matrices, so that a pair of parallel spaced apart wires will extend through each rib the ribs forming an intersecting array of ribs in the support frame, and wherein protruding wires along at least two sides of one of the arrays are bent so as to make contact with wires of the other array and the ends of the bent portions of the wires of the one array are welded to the protruding ends of the wires in the other array, so as to maintain separation between the two matrices.
