A high modulus textile cord (50) with at least triple twist (T1, T2, T3) comprises at least N strands (20a, 20b, 20c, 20d), N being greater than 1, twisted together with a final twist T3 and a final direction D2, each strand being made up of M pre-strands (10a, 10b, 10c), M being greater than 1, themselves twisted together with an intermediate twist T2 (T2a, T2b, T2c, T2d) and an intermediate direction D1 opposite to D2, each pre-strand itself consisting of a yarn (5) which has been twisted on itself beforehand with an initial twist T1 (T1a, T1b, T1c) and the direction D1, in which at least half of the N times M yarns have an initial elastic modulus denoted Mi which is greater than 2000 cN/tex. This textile cord can advantageously be used as a reinforcer in tires for vehicles, particularly in the belt or carcass reinforcement of these tires.

Provided is a multi-twisted steel cord for reinforcing a rubber article, the steel cord having cord strength with a small loss as compared to the total strength of filaments constituting the cord and a high rubber penetration. The steel cord includes a plurality of twisted strands in a multi-twisted structure, each strand including a plurality of twisted filaments in two or more layers, in which at least some of the filaments have a tensile strength of 3,000 MPa or more, the steel cord satisfying a filament occupancy of 48% or more and less than 54%, a cord twist angle of 78 or more and less than 84, an average crossing angle between adjacent filaments other than wrapping filaments of less than 17, and a gap between adjacent sheath filaments constituting the strand of 0.065 mm or more.

A braided structure that includes a core and a sheath is provided. The core includes a yarn formed at least in part from an aromatic polymer (e.g., an aromatic polyester/liquid crystalline polymer or an aramid polymer), and the sheath, which includes a plurality of ultra high molecular weight polyolefin yarns, is braided around the core. The sheath has an overall diameter ranging from about 60 micrometers to about 650 micrometers. Despite its small diameter, the braided structure can be creep resistant and abrasion resistant while at the same time exhibiting low elongation, a high load at break, and high stiffness. The braided structure can be used in medical applications such as sutures, load bearing orthopedic applications, artificial tendons/ligaments, fixation devices, actuation cables, components for tissue repair, etc.

A method for manufacturing a rope structure comprising providing, around a first roller and a second roller, a loop including a plurality of twisted strands. The method further comprising feeding a plurality of body strands onto the loop, feeding including, with the plurality of body strands connected to the loop, moving the loop about the first roller and the second roller to cause the body strands to lay and be twisted on the plurality of twisted strands.

Methods and systems for ropes used to catch livestock such as a cattle roping lariat. In one embodiment, the lariat includes a set of strands, each strand including a set of yarns surrounding a central core. The set of strands are twisted to form a twisted rope. The lariat is manufactured using a set of components including a head box, a tree-cross box with a branched strand tree device and a cross device, and a tail box.

A torque coil (two-layer coil structure) of the disclosed embodiments includes an inner coil formed by spirally winding metal wire, and an outer coil arranged to be in close contact with the outer periphery of the inner coil and formed by spirally winding metal wire. A winding direction of the inner coil and a winding direction of the outer coil are opposite from each other, and when the torque coil is twisted in the circumferential direction in which the diameter of the inner coil is increased, a change amount of the diameter of the outer coil is larger than a change amount of the diameter of the inner coil. The two-layer coil structure has high twisting rigidity, thus suppressing the occurrence of kinks due to rotational resistance.

The tire has a radial carcass reinforcement, the seat diameter of which is strictly greater than 19.5 inches. The metal reinforcing elements of the at least one layer of the carcass reinforcement are layered cords which include several steel threads that have a weight content of carbon C such that 0.01%C<0.4%. The at least one carcass reinforcement layer has a breaking force per unit width of between 35 daN/mm and 75 daN/mm, and the diameter of the cords is greater than 0.7 mm.

In a tire the strength of steel cord and the resilience of rubber are a successful combination. However, in some specific areas of a tire, more elongation is expected from the steel cord, while still a sufficient degree of stiffness is expected. A steel cord is presented that has these properties. The steel cord comprises two or more steel elements that are twisted together. The steel elements comprise one or more steel filaments. In total the steel cord comprises N filaments, each with a cross sectional area A. When the steel elements are individualised out of the steel cord they show a helix pitch length of L.sub.o, while a single pitch has a centre line length of S. The inventive steel cord shows a P value of at least 50 newton, wherein P=NE (A/S).sup.2. Further methods are presented to produce this steel cord.
