Abstract:
A process for producing a high strength rope comprising the step of i) providing a uniaxially oriented tape (10) comprising ultra-high molecular weight polyethylene, the tape (10) having a tensile strength of at least 0.9 GPa, and ii) simultaneously twisting and fibrillating the tape (10) into a twisted strand of fibrillated tape with a coherent network of filaments and fibrils. A rope obtainable by the process and products comprising the rope are also disclosed.
Abstract:
Toron (3) comportant un groupement de fils torsadés (8), et étant agencé pour comprendre, sur une première partie (1 ) de sa longueur : une gaine (4) contenant le groupement de fils torsadés, et un produit souple de remplissage (7) comblant un interstice périphérique (6) situé entre la face intérieure de la gaine et la périphérie du groupement de fils torsadés, et sur une deuxième partie (2) de sa longueur, distincte de la première partie : un matériau (9) couvrant la périphérie du groupement de fils torsadés, ledit matériau étant adhérent sur les fils torsadés du groupement.
Abstract:
A wire rope (10) includes a plurality of strands (12). The strands are formed from individual wires or filaments (14). The strands are wound about a central axis. A conduit (16) also extends along said central axis. The conduit has walls that are foraminous and permit radial flow of a lubricant. The lubricating compound is injected into the channel (18) defined by the conduit. The lubricating material migrates through the orifices in the conduit wall and radially outwardly therefrom.
