  • Patent number: 4847976
    Abstract: In order to produce a corrosion protective stressing cable having a protective jacket a stressing element bundle is prefabricated in a first production step. Thereby, the individual wires anchored in an anchoring body are inserted in a correct order into and through a perforated plate, at which the corrosion protective mass is fed into the interstices between the individual wires. The wires are thereafter bundled in a forming body at a simultaneous distribution of the corrosion protective mass therein. In a second production step a protective jacket is pulled onto the prefabricated bundle. To this end the protective jacket is clamped at one of its ends in an application apparatus, by means of which the protective jacket is pulled over the bundle and simultaneously a corrosion protection mass is fed into the interstice between the outer surface of the bundle and the protective jacket. This allows a production of a relatively long cables at a relatively low temperature expenditure on structures.
