Abstract: A method for straightening wire or strip material by a dressing device comprising straightening rollers engaging on opposite sides of the passing-through material in an offset manner, of which, some are automatically activated according to a model which has been stochastically determined on the basis of input data of the material and data relating to the wire and the dressing device that is determined during the passing of the material through the dressing device, such that requirements for straightness are met, wherein the position of at least one straightening roller is continuously adapted on the basis of said data detected during the passage through the dressing device, which data are representative of the target straightness, wherein (i), the size and direction of the forces acting on the straightening rollers and/or (ii) the temperature of the material before and after passing through the assembly of straightening rollers, and/or (iii) the position of the material is measured at each of the straightenin

Abstract: A straightening roller unit for steel material in wire, rod, or strip form that is to be straightened with straightening rollers cooperating in pairs, which are configured to be positioned against the material to be straightened and to be raised from it. The straightening rollers are driven, and the advancement force required for the straightening operation is introduced into the material to be straightened by friction of the straightening rollers.

Abstract: A welding machine for manufacturing wire nets from mutually perpendicular longitudinal and transverse wires welded at the points of intersection comprises a device for feeding the longitudinal wires in a horizontal welding plane, two devices for simultaneously inserting two transverse wires (Q,Q'), arranged at equal distances on either side of insertion lines (K,K'), a welding electrode arrangement for carrying out two-point welding in the direction of the longitudinal wires, and two feeder arms (8,9) for transferring the transverse wires from the insertion lines to the welding lines (S, S'). The feeder arms are fitted with clamping devices (11,12) for the transverse wires and can be moved together back and forth between the insertion lines and the welding lines along predetermined tracks (U, U'; O, O').
