Title
(EN) METHOD FOR MAKING AN APERTURED WEB
(FR) PROCÉDÉ DE FABRICATION D'UNE TOILE À OUVERTURES
Abstract
(EN)
A method for making an aperture web, comprising moving a micro-textured web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web. A method for making an aperture web, comprising forming microtextures on a web, and continuously moving the web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web.
(FR)
La présente invention concerne un procédé de fabrication d'une toile à ouvertures, comprenant le déplacement d'une toile micro-texturée à travers un premier élément comprenant des éléments mâles et un second élément comprenant des éléments femelles discontinus, les éléments mâles étant disposés selon un motif en quinconce, et ayant une forme telle qu'elle permet la formation d'ouvertures quadrilatérales dans la toile micro-texturée. L'invention concerne également un procédé de fabrication d'une toile à ouvertures, comprenant les étapes consistant à former des microtextures sur une toile, et à déplacer en continu la toile à travers un premier élément comprenant des éléments mâles et un second élément comprenant des éléments femelles discontinus, les éléments mâles étant disposés selon un motif en quinconce, et ayant une forme telle qu'elle permet la formation d'ouvertures quadrilatérales dans la toile micro-texturée.
