    Abstract: A securing device is provided comprised of a reactive fiber component and at least one of a terminating fiber component and an initiating fiber component. The reactive fiber component includes at least one of the following: an undrawn polymer fiber and a substantially undrawn polymer fiber, wherein the first reactive fiber component is operative to stretch responsive to a load. The terminating fiber component is in a compressed state and is operative to elongate to a length at which the terminating fiber component is operative to prevent further stretching of the first reactive fiber component responsive to the load. The initiating fiber component is operative to break responsive to a predetermined force and permit the first reactive fiber component to stretch responsive to the load.

    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.
