  • Patent number: 4117582
    Abstract: Process for winding and unwinding a parallel wire strand consisting of a multiplicity of individual wires onto and from a cable drum, and apparatus for performing such process. In the winding process, the parallel wire strand which is supplied in generally circular cross-sectional shape is fanned out so as to form a layer or layers of individual wires disposed in generally parallel position. The lead ends of the wires are anchored and such anchored end is mounted in a support therefor in the interior of the drum in such a manner that the subsequent winding of the individual wires in layers on the drum is without tension. In the unwinding operation, the individual wires are reformed into such circular cross-sectional strand shape at the bridge construction site, with corrosion-preventing material being applied to the individual wires during such unwinding, and a tubular casing of metal or plastic subsequently formed around the wires for sealing the same.
