Abstract
(EN) The invention relates to a method and device for applying electric discharges to sheets in order to perforate same. The method comprises the impregnation or deposition of substances, such as paints, dyes, colouring agents and substances having different degrees of hydrophobicity, in/on the sheets during electric perforation. The perforation device comprises electric perforation means, including a liquid or gel as a conduction medium for the electric discharge and as supports for the sheets, as well as a medium for dissolving or mixing salts, paints, dyes, colouring agents and substances having different degrees of hydrophobicity.
(ES) La presente invención comprende un método y un aparato para la aplicación de descargas eléctricas sobre láminas para su perforación. El método incluye la impregnación o deposición de sustancias como pinturas, tintes, colorantes y sustancias de distintos grados de hidrofobicidad en las láminas durante la perforación eléctrica. El aparato de perforación incluye medios de perforación eléctrica, con líquido o gel como medio de conducción para la descarga eléctrica, y como soportes para las láminas; también como medio para disolver o mezclar sales, pinturas, tintes, colorantes y sustancias de distintos grados de hidrofobicidad.
(FR) La présente invention concerne un procédé et un appareil permettant l'application de décharges électriques sur des feuilles afin de les perforer. Le procédé consiste à imprégner ou déposer des substances telles que des peintures, des teintures, des colorants et des substances présentant divers degrés d'hydrophobie sur les feuilles au cours de la perforation électrique. L'appareil de perforation comprend des moyens de perforation électrique, avec du liquide ou du gel comme moyen de conduction pour la décharge électrique, et en tant que supports pour les feuilles; mais également comme moyen pour dissoudre ou mélanger des sels, des peintures, des teintures, des colorants et des substances présentant divers degrés d'hydrophobie.
