Abstract

Fil métallique revêtu d'une gaine adhérente en matière synthétique à haut poids moléculaire et faiblement visqueuse à la température de fusion, destiné à être utilisé pour confectionner des toiles, tressages ou grillages en fil métallique pour l'égouttage, le triage et/ou le classement de produits corrosifs granuleux. Selon l'invention, l'épaisseur 3 de la gaine 2 en matière synthétique est égale à au moins 0,3 fois diamètre 4 du fil métallique 1. Cette épaisseur est de préférence comprise entre 0,5 et 4,0 fois ledit diamètre. Application à la fabrication de toiles métalliques de criblage et/ou d'égouttage.Metal wire coated with an adherent sheath of synthetic material of high molecular weight and low viscosity at the melting temperature, intended to be used to make cloths, braids or wire mesh for draining, sorting and / or classification of corrosive granular products. According to the invention, the thickness 3 of the sheath 2 made of synthetic material is equal to at least 0.3 times the diameter 4 of the metal wire 1. This thickness is preferably between 0.5 and 4.0 times said diameter. Application to the manufacture of metal screens for screening and / or draining.
