A device and a method for manufacturing a metal tube-covered optical fiber cable; the method, comprising the step of, while manufacturing a metal tube (6) by forming a metal tape (2) in a tubular body and welding the joint of the metal tube (2), feeding an optical fiber (11) protected by a jerry substance into the metal tube (6) through a guide pipe (13) inserted in to the metal tube (6) so that the tip thereof is positioned ahead of a welded position, wherein a damage of the guide pipe (13) by welding heat is reduced to increase the service life of the optical fiber, and a welding torch (5) for welding the joint of the metal tape (2) is reciprocatingly moved along the joint for welding, whereby the welding heat can be prevented from being concentrated into one position on the guide pipe.
L'invention concerne un dispositif et un proc~d~ de fabrication d'un c~ble de fibres optiques revÚtu d'un tube m~tallique. Le proc~d~, outre la fabrication d'un tube m~tallique (6) par formage d'une bande (2) m~tallique dans un corps tubulaire et soudage du raccord du tube (2) m~tallique, consiste ~ faire passer une fibre optique (11), prot~g~e par une matire g~latineuse, dans un tube m~tallique (6) ~ travers un conduit de guidage (13) ins~r~ dans le tube (6) m~tallique, sa pointe ~tant ainsi plac~e devant une position soud~e, ce qui r~duit l'endommagement du conduit de guidage (13) par la chaleur du soudage et augmente la dur~e de vie de la fibre optique. Un chalumeau soudeur (5) pour souder le raccord de la bande (2) m~tallique se d~place en va-et-vient le long dudit raccord. On peut ainsi ~viter de concentrer la chaleur du soudage sur un emplacement du conduit de guidage.
