  • Patent number: 4121629
    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 circulating feeders which carry deflector-pins and each of which has a working run 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 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 endless feeders circulate in a common plane which is parallel with the plane of production of the web, the deflector-pins project substantially perpendicularly from the common plane, and the working runs of the two feeders have in the neighbourhood of the welding zone a greater separation from one another than before and beyond the zone.

  • Patent number: 4116244
    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.
