Systems and methods for producing mesh from wires or rods with programmed changeable steps for the longitudinal and transverse wires. The longitudinal wires (1) and the transverse wires (12) may be fed from coils or be precut. The longitudinal wires are fed in receptacles (2) on carriers (3) with the carriers being found on prefeeder carrier (4), a feeder carrier (6) with grippers (7) transports them towards the welding heads (10) and the produced mesh (20) is received by a mesh carrier (14). The carriers (3) with the receptacles (2) for the longitudinal wires on the prefeeder carrier (4), the grippers for the longitudinal wires (7) at the feeder carrier (6) and the welding heads (10) are displaced in the direction of the transverse wire without restrictions, generally in an unrestricted fashion, so as to correspond to the longitudinal wires being subjected to welding. The transverse wires are fed towards the welding heads to be welded with the longitudinal wires. The machine produces meshes with openings, grouping the longitudinal wires in groups and feeding the groups of longitudinal wires towards the welding heads, adjusting the position of the related mechanisms to the position of the longitudinal wires.

A method for producing a wire mesh mat that consists of intersecting longitudinal and transverse wires and to a mesh welding facility for welding a wire mesh mat from intersecting longitudinal and transverse wires, comprising a clocked supply device for a sheet of longitudinal wires in an X direction, a feed device for transverse wires that lie perpendicular to the longitudinal wires and to a welding portal for welding the wires at their intersections.

A self-furring welded wire mesh for reinforcing generally planar concrete and stucco structures is formed of a matrix of longitudinally and transversely extending wires disposed about a first common plane and welded together at their intersections. A selected plurality of the longitudinally extending wires each define a plurality of generally V-shaped spacing furrs therein extending generally perpendicular to the first plane with the bottoms of the furrs being disposed in a second plane spaced from the first plane a distance substantially equal to one-half of the predetermined thickness of the concrete panel. The spacing furrs in the selected longitudinally extending wires are located so as to be longitudinally and transversely staggered along the mesh. The spacing furrs are formed by pushing portions of the selected longitudinal wire perpendicular to the axis of the wires while holding an upstream portion thereof in a fixed disposition so as to form these without damaging or thinning the wires along the spacing furrs.
