Title (EN) UNIFORM MELTBLOWN FIBROUS WEB AND METHODS AND APPARATUS FOR MANUFACTURING
(FR) VOILE FIBREUX DE FUSION-SOUFFLAGE UNIFORME ET SES PROCEDES DE FABRICATION AINSI QUE L'APPAREIL ASSOCIE
Abstract: front page image
(EN)Multilayer meltblown fibrous webs, as well as apparatus and methods of forming the webs. The webs are produced on a rotating collector that also moves parallel to its longitudinal axis. The webs are thus formed in a helical process, and the resulting tubular web is separated in a direction parallel to a helix angle. By separating the tubular web in a direction parallel to the helix angle, a flat multilayer meltblown fibrous web is provided that allows for incorporation of feathered edges formed during the article's manufacture.
(FR)L'invention concerne des voiles fibreux de fusion-soufflage multicouches ainsi qu'un appareil et des procédés de formation de ces voiles que l'on produit sur un collecteur rotatif se déplaçant parallèle à son axe longitudinal. Les voiles sont formés par coupe hélicoïdale et le voile tubulaire ainsi obtenu est séparé dans un sens parallèle à un angle de torsion. En séparant le voile tubulaire dans un sens parallèle à l'angle de torsion, on obtient un voile de fusion-soufflage plat multicouches contenant des bords arrondis formés pendant la fabrication de l'article.
