An apparatus for filling the interspaces between leads of a bundle of leads, which may be optical or electrical leads, with a water-repelling compound characterized by a filling head having a pre-filling chamber and a main filling chamber. The leads are supplied via a common admission channel to the pre-filling chamber which has a channel opening that is selected to be only slightly larger than the diameter of the envelope of the leads combined to form a bundle of leads. The pre-filling chamber is followed by a coating nozzle having a diminished cross section, which coating nozzle receives the bundle and discharges it into the main filling chamber.

Apparatus for filling interspaces between leads and a sheath of a cable

A method for covering at least one optical fiber with a protective layer comprises extruding the protective layer and embedding reinforcing elements in the protective layer to form a composite covering and simultaneously introducing the optical fiber into the composite covering. The method includes introducing a single waveguide or a plurality of waveguides, which may be formed into a bundle with a filling compound.
