Abrégé

A method for producing wire lattice mats comprising parallel longitudinal wires, which are connected to upper and/or lower transversal wires at the intersecting points of the longitudinal wires and the transversal wires by means of electric resistance welding, wherein two transversal wires disposed laterally at a distance are welded simultaneously to the longitudinal wires along two parallel weld lines, and wherein a plurality of longitudinal wires are fed in cycles in the production direction in a horizontal longitudinal wire feed plane, and the two transversal wires disposed at a distance are fed in cycles into the respective insertion line and into an insertion channel associated with each weld line and are cut to the respectively required length for the width of the wire lattice mats, wherein the transversal wires (Q1-Q4) are optionally guided in an upper (K1, K1') and a lower insertion channel (K2, K2') disposed along each of the two weld lines (S1-S2, S2-S2), such that optionally wire lattice mats are produced only with upper (Q), or only with lower transversal wires (Q'), or alternately with upper (Q) and lower transversal wires (Q'), or wire lattice mats are produced with upper (Q) and lower transversal wires (Q') disposed in pairs on top of each other, wherein in the case of the wire lattice mats having transversal wires (Q, Q') disposed in pairs on top of each other up to four transversal wires (Q1-Q4) are welded simultaneously to the longitudinal wires (L) of a wire lattice mat. The invention also relates to a system for carrying out the method.

Abrégé

Component which comprises two parallel, flat wire mesh mats (M1, M2) made from longitudinal and transverse wires (L1, L2; Q1, Q2) which cross one another and are welded to one another at the crossing points, straight frame wires (V1, V2) which hold the wire mesh mats at a predefined, mutual spacing and are connected at each end to the two wire mesh mats, and a central element which is arranged between the wire mesh mats and at a predefine spacing parallel to the latter and is formed from a dimensionally stable, thin barrier layer (T) which is penetrated by the frame wires and is held by the latter at a predefined spacing from each of the wire mesh mats.
