Systems and processes for feeding longitudinal wires in a mesh 3 production machine. Mesh 3 is produced by the welding of longitudinal wires 2 with transverse wires 6 at a welding unit 27. The longitudinal wires may be pulled from decoiler reel 40, straightened, and then deposited in longitudinals storage 19. They are then received by a longitudinals carrier 15 and transported towards welding unit 27. The longitudinal wires 2 are selectively rotated around their longitudinal axes with selected angle, and restrained until their welding with the transverse wires. This negates effects of any possible curvature acquired during their straightening with rollers 9, so that after their welding, the resulting mesh 3 is produced planar with the distortion stresses neutralized.

The present invention relates to machines, systems and processes for feeding longitudinal wires (2) for mesh (6) production. Welding of longitudinal wires (2) with transverse wires (4) at welding unit (57) produces mesh (6). Longitudinal wires (2) are controllably rotated around their longitudinal axes to selected angles, and restrained until their welding with transverse wires (4), thus negating effects of residual curvature from roller straightener (36) and resulting in mesh (6) produced planar with distortion stresses effectively neutralized. A wire collector (79) releases a first longitudinal wire (2) for guided travel laterally to a receptacle (45). A rotator unit (71) simultaneously controllably rotates this wire, while the collector (79) simultaneously receives the length of the next longitudinal wire. Particular rotator units (71) facilitate such operation. In some versions an advancement roller assembly (120) proximate to the welding unit (57) may advance longitudinal wires (2) through the welding unit, freeing a longitudinal wires carrier (31) to return to the longitudinal storage (32) and to receive a next set of longitudinal wires.
