Title: MACHINE AND METHOD FOR MANUFACTURING A REINFORCED NET AND REINFORCED NET
Abstract:
A machine for manufacturing a reinforced net (1, 10), which has hexagonal meshes comprising a plurality of permanently deformable wires (2, 2', 3, 3') and at least one reinforcing element (5), comprises a mechanism for the reciprocal coiling of first wires (2, 2') and second wires (3, 3') in twos, which mechanism is provided with passages for the reinforcing elements (5), and a feed system for the first wires (2, 2'), fed in from a plurality of containers (90, 90') that are mounted on board the machine and provided internally with a predetermined length of said first wires (2, 2'), for part of the second wires (3), fed in alternately with the first wires, so as to be interwoven therewith in twos in the coiling mechanism, and for the reinforcing elements (5), fed into the machine, wherein, for all the reinforcing elements (5), a wire receptacle (202) is provided for one of said second wires (3'), the wire receptacle being rotatable around the reinforcing element. The invention also relates to a multiple-twist net with hexagonal meshes and a method for producing such a net.
