<p>A method for feeding installations for the automatic forming of electro-welded metal nets having special contoured shapes. The feeding of the longitudinal bars is provided with whole bars (3), not segments. The whole bars have a length that is equal to the length of the special net or of the nets to be built and/or shorter than the total length, considering any voids. The longitudinal bars (3) are managed individually and are optionally cut, upstream of the electric welding apparatus (6), by an adapted automatic shears (10), equipped with a respective retainer (9). The apparatus furthermore has an upstream transfer carriage (5), which is provided with a plurality of automatic clamps (4) that move the rods (3) toward the electric welding assembly (6), works below the working plane, while downstream another transfer carriage (7), also provided with automatic clamps for gripping the formed net, works above the working plane. Both carriages operate synchronously with each other and with the other assemblies.</p> |
