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 connection structure includes a multi-thread coil formed by winding first metal element wires formed of a first metal and second metal element wires formed of a second metal arranged between a first metal body including the first metal and a second metal body including the second metal. The first metal body is connected to the first metal element wires of the multi-thread coil, and the second metal body is connected to the second metal element wires of the multi-thread coil. The connection structure imparts improved flexibility to the connection between the first and second metal bodies, and an appropriate connection can be provided even when the first and second metal bodies are made of dissimilar metals.

An apparatus is provided which makes a border wire having a rectangular cross-section. The apparatus is adapted to receive a roll of wire having a circular cross-section, straighten the wire and change the cross-section of the wire to rectangular. The reconfigured wire is then accumulated, passed through another straightener, cut to size and then bent into a rectangular configuration. Opposed ends of the piece of wire having a rectangular cross-section are welded together to complete the border wire. The apparatus has an ejector which removes the completed border wire from the apparatus.

Reinforcing is disclosed comprising a reinforcing bar extending along a portion of the length of the reinforcing and a termination extending along an end portion of the reinforcing. The termination may have a body extending in a longitudinal direction and a lateral engagement face formed on the body. The engagement face may incorporate locking formations thereon arranged to interfit with a complementary shaped termination to form an interlock arranged to accommodate loading applied in the longitudinal direction.

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.

A mold is used to form a solder joint to join the distal end of the guidewire to a wire coil. The mold has a cavity that can have different configurations so that the solder joint can be any of bullet shaped, micro-J shaped, cone shaped, truncated cone shaped, or have a textured surface.
