    • 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. In a further embodiment of the invention, the encased circular wire strand is wound simultaneously on a pair of cable drums so as to compensate for differences in length between the wires positioned on the outside and those wires positioned on the inside so as to avoid tension in the wires.
    • 用于将由多根单独的线构成的平行线股线卷绕和退绕到电缆卷筒上和从电缆卷筒上卷绕的方法以及用于执行这种处理的装置。 在卷绕过程中,以大致圆形横截面形状供给的平行线束被扇形出来,以形成大致平行的位置设置的单根线的层或多层。 电线的引线端被锚固,并且这样的锚固端部以滚筒的内部的方式安装在支撑件中,使得在滚筒上的各个电线的随后的卷绕没有张力。 在退绕操作中,单独的线在桥梁施工现场被重新形成为这种圆形横截面股线形状,在这种退绕过程中将防腐蚀材料施加到各个线上,随后形成金属或塑料的管状壳体 用于密封的电线。

    • The present invention relates to synthetic cables comprising a core formed of high modulus threads arranged in parallel to each other, wherein the ends of the cable comprise splice-type termination ends (1), wherein each splice (1) comprises high modulus threads arranged in parallel to each other forming an eyelet (11) on each splice, wherein each leg of the threads (13, 13) comprising each splice is connected to a thread (21) that forms the core of the cable, wherein the splice threads (13, 13) and the core threads are arranged in parallel to each other at an interpenetration region (12).The present invention further discloses a method for manufacturing a synthetic cable comprising a core formed of high modulus threads arranged in parallel to each other, wherein the ends of the cable comprise splice-type termination ends (1), wherein each splice (1) comprises high modulus threads arranged in parallel to each other, which method comprises the steps of: individually connecting each leg of the threads (13) comprising a positive splice to a thread (21) of the beginning end of the cable core (2) forming a loop; joining the threads of the positive splice (13) so as to form a loop, straining all the threads, wherein the splice threads (13) and the core threads (21) are arranged in parallel to each other at an interpenetration region (12); applying a normal compression force at the interpenetration region (12) of the positive splice (1); applying at least one protective element (32) along the entire length of the cable; individually connecting each leg of the threads (21) that form a negative splice to a thread (21) of the final end of the cable core (2) forming a loop; joining the threads (13) of the positive splice so as to form a loop, straining all the threads, wherein threads (31) from the splice and threads (21) from the core are arranged in parallel to each other at an interpenetration region (12); and applying a normal compression force at the interpenetration region (12) of the negative splice.
