Abstract

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.
