Method for shaping a material with a reticular structure, plant for performing same and reticular material resulting from the method. This method is applicable for handling a reticular tubular structure, in particular one of those obtained by extruding a synthetic plastics material, wherein its filaments, which form the sides of the net mesh, have a greater thickness at the crossover points than the actual thickness of the filaments. This method consists in the synthetic plastics material with a reticular tubular structure being subjected, while hot and with its tubular flattened shape, to two-dimensional molecular orientation operations, through drawing and widening, followed by an operation to equal the thicknesses of the reticular tubular flattened structure, already oriented, by laminating it in a calendering machine. |
