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.

The present disclosure relates to an automatic forming machine for plant growth supports, comprising a ring rolling system with a ring rolling unit, a mold system with a mold unit, and a welding system, which are all disposed on a machine frame, wherein the ring rolling unit can roll a metal wire and make the metal wire be formed into a ring with an opening in the mold unit; the mold system is for carrying the ring and making two free ends of the ring with an opening aligned or alternately overlap with each other; the welding system welds can weld the opening of the ring carried by the mold unit, causing the ring to become a closed ring. The present disclosure has a high automatic degree and can reduce the production time and labor cost.

A method for shaping a wire material that moves from the upstream side to the downstream side includes a first step of feeding the wire material while pressing the wire material by a first roller group including a plurality of rollers driven by a motor and a second step of feeding the wire material while pressing the wire material by a second roller group including a plurality of rotatably supported rollers. The first step is provided upstream side of the second step, and a push-in amount that is the difference between the outer dimension of the wire material and the gap between rollers through which the wire material passes is larger in the first step than in the second step.
