Abstract:
A presente invenção está relacionada a cabos sintéticos compreendendo uma alma formada por fios de alto módulo dispostos em construção paralela, em que as extremidades do cabo compreendem terminais do tipo splice (1), em que cada splice (1) compreende fios de alto módulo dispostos em construção paralela formando um olhal (11) em cada splice, em que cada perna dos fios (13,13') que compõem cada splice é conectada a um fio (21) que compõe a alma do cabo, em que os fios do splice (13,13') e fios da alma (21) são dispostos paralelamente em uma região de interpenetração (12). A presente invenção também está relacionada a um método para fabricar um cabo sintético compreendendo uma alma formada por fios de alto módulo dispostos em construção paralela, em que as extremidades do cabo compreendem terminais do tipo splice (1), em que cada splice (1) compreende fios de alto módulo dispostos em construção paralela, compreendendo as etapas de: conectar individualmente cada perna dos fios (13) que compõem um splice positivo a um fio (21) da extremidade inicial da alma do cabo (2), formando um loop; unir os fios do splice positivo (13) de modo a formarem um loop, tensionando todos os fios, em que em que os fios do splice (13) e fios da alma (21) são dispostos paralelamente em uma região de interpenetração (12); aplicar uma força normal de compactação na região de interpenetração (12) do splice positivo (1); aplicar pelo menos um elemento de proteção (32) em toda a extensão do cabo; conectar individualmente cada perna dos fios (21) que compõem um splice negativo a um fio (21) da extremidade final da alma do cabo (2), formando um loop; unir os fios do splice positivo (13) de modo a formarem um loop, tensionando todos os fios, em que em que os fios (31) do splice e fios (21) da alma são dispostos paralelamente em uma região de interpenetração (12); e aplicar uma força normal de compactação na região de interpenetração (12) do splice negativo.
Abstract:
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 furher 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.
Abstract:
An annular core stranded bead wire having a reduced weight and offering ease in manufacturing and handling and a vehicle tire using such a bead wire are provided. The annular core stranded bead wire 2 has a metal annular core 11 and a sheath layer 13 constituted of a side wire 12 wound in a spiral pattern around the annular core: the side wire 12 is prepared by wrapping a side wire main body 21 made of aramid fiber with a pair of steel wires 22.
Abstract:
The present invention discloses a drive system for theatrical rigging, comprising a drive rope and a drive pulley. The drive rope has a fiber or cable core, surrounded by a plastic jacket. Formed on or in the surface of the drive rope are traction features that engage corresponding grooves in the drive pulley.
