Verfahren zum Ummanteln eines Kunststoffrohres mit einem Metallband und Schweißstation zum Verschweißen der einander überlappenden Längsränder des Metallbandes

摘要

The method has a plastics pipe (16) wrapped with a metal band (26), and the overlapping longitudinal edges of the metal band welded together via a welding head (40). One of the longitudinal edges of the metal band is lipped, with the metal band wrapped around the plastics pipe so that the lipped longitudinal edge projects radially outwards, for detection by a sensor (36) controlling the movement of the welding head.
