The invention relates to a method and a device for producing wire lattice mats, consisting of longitudinal and transverse wires (L1, L2; Q1) which cross each other and are welded together at the points where they cross by means of welding electrodes, according to the resistance welding technique. Before being welded with the transverse wires, said longitudinal wires are moved together transversally to the advance direction of the longitudinal wires, horizontally in relation to the welding electrodes (19, 20), in selected stages after a predetermined number of welding cycles, and then secured again in the new positions. |
