The invention relates to a device for the welding of a wire mesh grid of intersecting longitudinal and transverse threads, with a rotating upper and lower electrode in the form of a discoid polygon, whereby at least the upper electrode (2) may be raised and lowered and the upper and lower electrodes (2, 6) may be rotated in the working position. In said position, one polygon surface runs parallel to the longitudinal threads, whereby the upper electrode and the lower electrode comprise an internal distribution channel (13, 15) on each polygon surface (8) for cleaning air, preferably compressed air and each distribution channel has at least one outlet opening (14, 14'; 16, 16') ending in the middle of the polygon surface. The upper electrode and the lower electrode each has a distribution piece (3; 3') for the cleaning air and the distribution pieces each have a connector (11), for supply with cleaning air and internal air channels (12), connected to the connector and to the distribution channels of the upper and lower electrodes, located in the working position.

The invention relates to a method for continuously producing structural elements (B) comprising two flat and parallel wire netting mats (M, M') consisting of crossing longitudinal and transversal wires which are welded at the points where they are jointed to each other by straight web wires (S, S') maintaining said wire netting mats at a predefined space from each other and of insulating elements arranged therebetween and crossed by the web wires. The inventive method consists in placing in parallel two wire netting mats in a production channel (2) at a distance with respect to each other corresponding to a desired thickness of the structural element. An insulation plate (I, I') made of a heat insulating material is arranged in the space between the parallel wire netting mats and several web wires are simultaneously inserted through at least one of the wire netting mats and a the insulating element from at least one alternate side in a an opposite direction to the diagonal on the planes which are perpendicular to the planes of the wire netting mats, said web wires being then welded to the wires (L, L'; Q, Q') of the netting mats. A device for carrying out said method and the thus produces structural element are also disclosed.

Disclosed is a method for extracting and separating cut, magnetizable steel wires (S) from a loose, disordered wire supply (V). According to said method, at least one row of several steel wires (O, S') that are vertically arranged on top of each other in a single layer is formed from the steel wire supply by means of magnetic force. The top steel wire (O) of each row is isolated, and at least one end of each isolated steel wire is fixed while all other steel wires (S') of said row are dropped into the wire supply (V). The isolated steel wire/s is/are delivered to a device used for further processing. The invention also relates to a device for carrying out the inventive method.

Disclosed is a method for producing a lattice girder (G, G') comprising at least one upper chord (O), at least one lower chord (U, U'), and at least one strut wire (Z, Z') that extends back and forth between the upper chord and the lower chord, is bent in a zigzag-shaped manner, is provided with bending tips on the upper chord side and the bottom chord side, and is welded to the upper chord and the lower chord. The distance (T, T') between adjacent bending tips (S, S') of the strut wires is selected differently within a lattice girder. The lower chord can be fed on different feeding planes (X-X, X'-X') while the lattice girder is cut off the continuously produced bar of material in predetermined cutting positions.
