VERFAHREN UND VORRICHTUNG ZUR HERSTELLUNG EINES LICHTWELLENLEITERKABELS.

摘要

The method for manufacturing a cable sheath includes the steps of controllably driving a metal strip in a longitudinal direction and continuously trimming the side edges of the metal stirp. The trimmed metal strip is continuously formed into a hollow tubular element by continuously welding longitudinally abutting edges of the hollow tubular element. The hollow tubular element is continuously cooled in the vicinity of the welding by surrounding at least 60% of its circumferential surface with a coolant. The resulting longitudinal welded seam is maintained free of the coolant and the cooled hollow tubular element is continuously drawn in the longitudinal direction.
