PATENTANSPRUCH:PATENT CLAIM: Verfahren zum Herstellen dünnwandiger Falzrohre aus Band, das aus einem nicht oder schwer lötbaren Werkstoff, z. B. aus Aluminium oder dessen Legierungen, bestehen kann, bei dem die Falzverbindung durch eine nach dem Einbringen durch Erwärmen mit dem umgebenden Werkstoff innigst verbundene Kunststoffeinlage abgedichtet wird, dadurch gekennzeichnet, daß nach dem Falzen des Rohres (ä) in den Falzspalt (b) ein Kunstharz (c) in pulverisierter oder flüssiger Form eingebracht und danach oder währenddem das Rohr (α) durch eine Wärmevorrichtung gezogen, das Harz dabei in dünnflüssigen Zustand versetzt und nach dem Verlassen der Wärmevorrichtung zum Erhärten gebracht wird.Process for producing thin-walled folded tubes from tape made of a material that cannot be soldered or is difficult to solder, e.g. B. made of aluminum or its alloys, in which the folded joint is sealed by a plastic insert that is closely connected to the surrounding material after it has been introduced by heating, characterized in that after folding the tube (a) into the folding gap (b) a synthetic resin (c) is introduced in powdered or liquid form and thereafter or while the pipe (α) is pulled through a heating device, the resin is rendered thin and hardened after leaving the heating device.
