Abstract: In a process for continuous production of longitudinally welded metal tubing, in which a metal strip is withdrawn from a strip supply, gradually shaped into a tubing with an open longitudinal slit, and the longitudinal slit is sealed by soldering or welding, a lubricant is introduced into the open slit tubing before sealing.

Abstract: In a process for producing longitudinally welded tubes, a metal strip, which is continuously pulled from a supply, is gradually formed into a slit tube and the longitudinal slit of said slit tube is welded. The metal strip (2) is pulled through a plurality of drawing dies (8, 9, 10, 11) arranged one behind the other and having a diameter that decreases in production direction, and in each of the drawing dies (8, 9, 10, 11) is increasingly bent in circumferential direction. The slit tube is closed in a last forming step (15) immediately in front of the welding point.

Abstract: A method for producing an optical cable with a metal tube and at least one optical fiber arranged in the metal tube, wherein optical fiber(s) are inserted into a slotted tube, the longitudinal slot in the slotted tube is welded, and the diameter of the welded tube is reduced. After the reducing operation, the welded tube is gripped by a draw-off device and conveyed in the finishing direction and wound up onto a draw-off disk. Between the draw-off device (10) and the draw-off disk (11), a force which causes elastic elongation of the metal tube (13) in the finishing direction is applied by the draw-off disk (11), and the extent of the elastic elongation is regulated through this force.
