Improvements, with the corresponding device, for obtaining elastic fabrics, based on sewn rubber yarn, essentially characterized by passing under tension a rubber thread of indefinite length, between the zig-zag sewing of the machine and the fabric, being said zig-zag, as a bridge over the thread, completing the sewing with the contribution of normal thread coming from the bobbin, with which the tensioned rubber thread does not intervene directly in the sewing work, which it is only for fixed retention of that one.
