Abstract

Provided is a machine for manufacturing a reinforced net with hexagonal meshes having a plurality of permanently deformable wires (2, 2', 3, 3') and at least one reinforcing element (5). The machine comprises a mechanism for the reciprocal coiling of first wires (2, 2') and second wires (3, 3') in twos. The mechanism has 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'). Part of the second wires (3) are fed in alternately with the first wires, so as to be interwoven therewith in twos in the coiling mechanism. The reinforcing elements (5) are fed into the machine, wherein, for all the reinforcing elements (5), a reel (202) is provided for one of said second wires (3'). The reel is rotatable around the reinforcing element while the net is being woven and configured such so that high-strength wires, cables, or ropes can used as reinforcement elements.

Claims (5)

1. Machine for manufacturing a reinforced net that has hexagonal meshes comprising a plurality of permanently deformable wires and at least one reinforcing element, the machine comprising a mechanism for the reciprocal coiling of first wires and second wires in twos, which mechanism is provided with passages for the reinforcing elements, and a feed system for: - the first wires, fed in from a plurality of containers that are mounted on board the machine and provided internally with a predetermined length of said first wires, - part of the second wires, fed in alternately with the first wires so as to be interwoven therewith in twos in the coiling mechanism, and - the reinforcing elements, fed into the machine, wherein, for each reinforcing element, a reel is provided for feeding one of the remaining said second wires, the reel being rotatable around the reinforcing element.
2. Machine according to claim 1, wherein, for each reinforcing element, the two containers for feeding in the first wires that are closer, in use, to the reinforcing element are narrower than the others.
3. Machine according to any one of the preceding claims, wherein the reciprocal coiling mechanism comprises: - an upper pair of supports for rotatable semi-cylindrical bodies, the rotatable semi-cylindrical bodies each being provided with a through-hole through which a first or a second wire passes and being capable of being coupled in twos and rotatable in pairs, so as to form twisted portions of the net, at least one pair of said rotatable semi-cylindrical bodies further being provided with a groove to accommodate the reinforcing element while the wires are being coiled together or around said reinforcing element, - a lower pair of supports for rotatable semi-cylindrical bodies, the lower pair of supports and the semi-cylindrical bodies being in direct correspondence with the upper pair of supports and the related semi-cylindrical bodies and being moveable synchronously therewith, at least one pair of said rotatable semi-cylindrical bodies furthermore being provided with a groove to accommodate the reinforcing element, and wherein a plurality of wires are slidable between the semi-cylindrical bodies of one support of the lower pair of supports and the corresponding semi-cylindrical bodies of the corresponding support of the upper pair of supports.
4. Machine according to claim 3, wherein the supports for the semi-cylindrical bodies are bars that have a U-shaped cross-section and are positioned in pairs with the respective open edges of the U that face one another, lie in a vertical plane of symmetry and are moveable in the direction of their length, a plurality of through-seatings being made in the edges of each of the bars of each pair facing the respective edges of the paired bar, each through-seating facing a similar seating made in the edges of the other bar of the same pair for the semi-cylindrical bodies, wherein each groove in the semi-cylindrical bodies continues respectively over the edge of each of the bars into another groove and wherein the grooves in the semi-cylindrical bodies and the grooves in the edges of the bars have a depth slightly greater than the radius of the reinforcing element and an overall width that is equal to the width of a mesh of the net, plus the diameter of the reinforcing element.
5. Machine according to claim 1, substantially as herein described with reference to any embodiment disclosed.
