Abstract

Manufacturing method of extruded lattice structures and, more particularly, of plastic networks, extruded and oriented of square or rectangular mesh and with three threads, in which structure all the threads are oriented and the threads of the two outer layers cross each other yes substantially perpendicular without being joined, the inner and outer bundle of wires only being coupled by intersections or welded or single-piece junctions with the third intermediate bundle of wires, the three bundles of wires having, at no point in the reticular structure, any common point of intersection, so that the main structural elements (namely the perpendicular threads) of the network have no mutual joints, allowing the threads to be oriented substantially uniformly along their lengths, which in turn allows to eliminate the weaknesses of the transition points and, due to the absence and, due to the absence of mutual unions, the They also mimic the tear lines between the two structural elements, characterized in that it comprises extruding a three-wire tubular network in three concentric layers, interior, intermediate and exterior, causing the extruded network tube to rotate around its axis, so that the Inner bundle or outer bundle of yarns follows a spatially fixed helical path, while outer bundle or inner bundle of yarns extends perpendicular to it, and the intermediate bundle of yarns remains at an angle with the yarns of the other bundles, cutting the net tube between a pair of contiguous threads of the thread bundle following said fixed helical path, dragging out the continuous sheet cut from net thus formed in a tangential direction and aligned with the helix angle of said helical path, subjecting the web continuous sheet to molecular stretching and orientation in a direction parallel to the direction of said inner or outer threads and, finally First, subject the monoaxially oriented sheet to stretching and molecular orientation perpendicular to the direction of the first orientation.
