Abstract

A method for producing tubular membranes creates 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. At least some of the threads (12) form a transversal connection (16) between adjacent longitudinal threads (14) in between the web-type connecting lines (14). A predefined membrane material (18) is applied to the tubular member (10).
