Method for producing a wire cable and use of said method

Abstract

The invention relates to a wire cable ( 12 ) which is produced by producing the wires already in the cable configuration by layer construction. Preferably, the wires are already formed onto terminal couplings. The wire cable ( 12 ) so produced is suitable for specific purposes only. It is advantageous in that it is not influenced by variations in quality of the starting product or by variations in manufacturing parameters. The inventive wire cable ( 12 ) is used for applications where short cables are required and where their absolute regularity can be made use of. An important field of application of the inventive method is the production of samples for obtaining background data required for optimizing wire cable construction. According to the inventive method, samples of identical basic cable structure but different wire diameters and/or lay lengths of strands, a core wire and/or the cable are produced and the characteristic features of interest are determined. In the tests, different absolute values are found. However, the values in relation to each other show influences of geometry, i.e. wire diameters and lay length modifications. A comparison with samples produced according to conventional manufacturing methods can be used to find correctional variables which can be taken into consideration when required.

       5 . The method according to  claim 1 , wherein the composition of the wires is started in a wire position relative to each other which corresponds to or approximates the contact pressure of the wires onto each other under load of the wire rope, and the wires are fanned out on a subsequent short section to such an extent that they can then be built up separately from each other.  
   
   
       6 . The method according to  claim 1 , wherein the composition of the wires can be started at an angle of the wires to the cross sectional plane of the wire rope, which is equal to or approximates the angle when loading the wire rope, and the wires are then deflected at that angle which is designed to be without load.
