Abstract

Le procédé consiste à extruder un premier système de fils 5 parallèles à l'axe d'extrusion; à extruder, à partir de la même tête, un second système de fils 6 obliques par rapport au premier système et rencontrant ce dernier, de façon à former un filet; à calibrer ce filet pendant qu'il se trouve immergé dans un bain réfrigérant; à le couper parallèlement au, et le long du premier système de fils 5; et à assujettir la bande ainsi obtenue à une traction uniforme exercée dans la même direction P que la direction d'extrusion, et/ou dans une direction P' transversale.The method consists in extruding a first system of wires 5 parallel to the extrusion axis; in extruding, from the same head, a second system of son 6 oblique with respect to the first system and meeting the latter, so as to form a net; in calibrating this net while it is immersed in a cooling bath; in cutting it parallel to and along the first system of wires 5; and subjecting the strip thus obtained to a uniform traction exerted in the same direction P as the direction of extrusion, and / or in a direction P 'transverse.
