Verfahren zur Herstellung eines optischen Kabels aus einem Metallrohr

摘要

The cable mfr. has a metal band(5) formed into a slit sleeve(3) in which the optical fibres(2) are inserted, before welding the edges of the slit together and reducing the outer dia. of the sleeve, to form a metal pipe. The metal band, around which the welded, reduced dia. sleeve is fed in at least one winding. The force exerted on the sleeve by the drawing disc provides an elastic deformation of the sleeve of between 1 and 6%, which lifts the sleeve from the disc.
