The invention relates to a method for producing tubular membranes. In order to create a very inexpensive production method while obtaining very high output rates for tubular membranes, a tubular member (10) is formed from several threads (12) in such a way that at least some of the threads (12) are tightly tied together along web-type connecting lines (14) that are composed of longitudinal threads while at least some of the threads (12) form a transversal connection (16) between adjacent longitudinal threads (14) in between said web-type connecting lines (14), and a predefined membrane material (18) is applied to the tubular member (10).

L'invention concerne un procédé servant à produire des membranes tubulaires. L'invention vise à créer un procédé de production très bon marché, permettant d'atteindre des taux de rendement très élevés en membranes tubulaires. A cet effet, un corps tubulaire (10) constitué de plusieurs fils (12) est réalisé de manière à obtenir une connexion pratiquement fixe d'au moins une partie des fils (12) le long de lignes de liaison (14) en forme de nervures constituées de fils longitudinaux. Entre les lignes de liaison (14) en forme de nervures, au moins une partie des fils (12) assure la liaison transversale (16) entre les fils longitudinaux voisins (14) et un matériau membraneux prédéfinissable (18) est appliqué sur le corps tubulaire (10).
