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 self-furring welded wire mesh for reinforcing generally planar concrete and stucco structures is formed of a matrix of longitudinally and transversely extending wires disposed about a first common plane and welded together at their intersections. A selected plurality of the longitudinally extending wires each define a plurality of generally V-shaped spacing furrs therein extending generally perpendicular to the first plane with the bottoms of the furrs being disposed in a second plane spaced from the first plane a distance substantially equal to one-half of the predetermined thickness of the concrete panel. The spacing furrs in the selected longitudinally extending wires are located so as to be longitudinally and transversely staggered along the mesh. The spacing furrs are formed by pushing portions of the selected longitudinal wire perpendicular to the axis of the wires while holding an upstream portion thereof in a fixed disposition so as to form these without damaging or thinning the wires along the spacing furrs.

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.
