The process for making fine metallic mesh (20) is disclosed comprising the steps of cladding an stray (50) of metallic wires (30) with an stray cladding material (65A) to provide an array cladding (65). The array cladding is drawn for reducing the diameter thereof and for reducing the corresponding diameters of each of the metallic wires for producing a clad array of fine metallic fibers within the array cladding. The stray cladding is fashioned into a mesh by weaving, braiding, crocheting and the like thereby forming a series of bends in the clad array for reducing interaction between adjacent portions of the array cladding. The array cladding material is removed for producing fine metallic mesh from the stray of the fine metallic fibers. Image

L'invention concerne un procédé de fabrication de maillage métallique (20) consistant à recouvrir un groupement (50) de fils métalliques (30) avec une matière de gainage (65A) de groupement de fils pour former une gaine (65) de groupement de fils. Cette gaine est étirée de façon à obtenir une réduction de son diamètre et par là même une réduction du diamètre de chaque fil métallique pour produire un groupement gainé de fines fibres métalliques à l'intérieur de la gaine. Cette gaine est façonnée en maillage par tissage, tressage, crochetage et analogues, une série de courbes étant formées dans le groupement gainé de façon à réduire les interactions entre des parties adjacentes de la gaine. La matière de gainage de groupement de fils est ensuite retirée pour produire un maillage métallique fin à partir du groupement de fibres métalliques fines.
