According to the method, the transversal wire or
rebar to be formed (1) and the longitudinal wires or rebars or other material of prismatic cross section (2), (3) are fed to the main forming and
welding machine subsystem, in a stepwise manner, at the appropriate distance each time, through a driving mechanism (22-30). At this location, the transversal wire (1) is
cut and then formed upon the action of a press (36).
Welding of the formed transversal frame with one of the two longitudinal wires is performed while the formed transversal wire is still restrained by the action of the press (38) at the formation location.
Welding with the second longitudinal wire is performed at the next production step, simultaneously with the
welding of the next transversal frame with the first longitudinal wire, at the formation location. After the
welding action, the transversal frame is released by the press and the forming tools (37-39), and the next production step is initiated. The product is made in a continuous shape and is
cut at the proper lengths, by a cutter (45).
