- EP-A1-0 806 257 a device for improving the yield strength and the ductility of wire is known, in which the wire is drawn over a plurality of staggered, driven rollers of a cold flow device, the bending direction changes between the rollers causing the above-mentioned material properties of the wire can be improved.
- Two cold flow devices can also be connected in series, one or both cold flow devices being driven. If only one cold flow device is driven, the wire between the two cold flow devices is additionally stretched. The wire can be fed to a device for straightening, cutting and / or welding.
- the disadvantage here is that, owing to the required drive of the rollers, no other device for improving the material properties can be used, « ⁇ bei missing important information on carrying out the disclosed method.
- EP-AI-0 806 257 also lacks any information about the methods and devices absolutely necessary for further processing of the wire. When using two cold flow devices, undefined stretching of the wire between the cold flow devices also takes place.

This document does not contain any statements about the material improvements of the cross wires and their feed to the mesh welding machine.
- the object of the invention is to avoid the described disadvantage of the known methods and devices and to provide a method and a system of the type specified in the introduction, which makes it possible to improve the mechanical-technological properties of hot-rolled steel without cold forming and to convert this material into lattice mats to process.
- the invention is also intended to make it possible to use hot-rolled steel, the mechanical and technological properties of which are not subject to microalloying or special heat treatment and quenching, e.g. Temporization have been improved.
- the method according to the invention is characterized in that the strand of material used to form the longitudinal rods is continuously drawn off from a wire supply via a spill and stretched to improve its mechanical-technological properties and is then trained and cut to length, that the longitudinal rods are then grouped and in accordance with the longitudinal Bar division arranged in the lattice mat to be produced, moved into the area of action of the lattice welding machine and inserted into it, and that the strand of material used to form the cross bars is continuously withdrawn from a wire supply via a spill and stretched to improve its mechanical-technological properties, the cross bar -
- the strand of material is then passed over a buffer store, first trained and the crossbar separated from the strand of material is fed to the grid welding machine in the welding cycle.
- the mechanical-technological properties of the longitudinal and transverse bars are preferably improved by increasing the ductility, with an approximately constant tensile strength increasing the yield strength, lowering the ratio of tensile strength to yield strength and increasing the uniform elongation.
- Each stretching device preferably consists of two rows of bending corner rolls arranged offset from one another, the bending corner rolls of at least one row being adjustable individually or in groups in the direction of the other row, and the diameter of the bending corner rolls being selectable in accordance with the diameter of the strand of material to be stretched.

- the ductility of the wire is significantly increased by the stretching.
- the wire can be processed more easily due to the high achievable uniformity of its properties and its low residual stress state after stretching. In order to achieve clear, reproducible results, it has proven to be advantageous to preset the stretching devices to match the diameter and wire qualities and to completely change the stretching devices when changing the diameter - 6 -
