ABSTRACT:
A multispot welding machine for producing a mesh web from arrays of wire running skew to the longitudinal direction of the web and crossing one another has two endless synchronously circulating feeders which carry deflector-pins and each of which has a straight working run; the runs are uniformly spaced from one another and each defining a different one of the edges of the mesh web to be produced, a wire-layer which is movable to and fro across the feeders and arranged to lay perpendicular to the runs a number of wires alternately about a corresponding number of deflector-pins on the working runs of the two feeders, and a welding zone having means for welding the wires together at their crossover points. The wire-layer has an auxiliary drive mechanism which is capable of imparting to the wire-layer, each time after the wire-layer crosses over the working run of a feeder, an additional rapid forwards motion in a direction parallel to the working runs and subsequent backwards motion so as to form loops of the wire around the deflector-pins.
