Optimized braid construction
Braided bodies having a reduced braid density while retaining high tensile properties. High tenacity fibers are braided together at a braid density of less than or equal to 20 picks per inch, wherein the tenacity of the braided body does not decrease with increasing braid density from 17 picks per inch to 19 picks per inch in length of the braided body.
ELASTOMER REINFORCEMENT CORD
Provided is an elastomer reinforcement cord in which the problem of stress concentration at an interface between an elastomer and a metal cord is solved and the durability is thereby improved. The elastomer reinforcement cord includes metal filaments (1a) and (1b), and a polymer material (3) having a melting point or softening point of 80° C. to 160° C. The elastomer reinforcement cord has a core (11) and at least one sheath layer (12). In a region surrounded by a line connecting the centers of the metal filaments constituting the outermost sheath layer at a cross-section in a direction orthogonal to an axial direction after vulcanization, when a region occupied by other than the metal filaments is defined as a gap region, the polymer material is contained in this gap region, and a filling rate, which is a ratio of the area of the polymer material, is higher than 120%, taking the area of the gap region as 100%.
CONSTRUCTIVE ARRANGEMENTS IN 6-STRAND SYNTHETIC TWISTED LARIAT ROPE
It refers to the invention of a 6-strand synthetic twisted lariat rope, a product used in Team Roping competitions. It is also used in cattle handling, when it is necessary to immobilize an animal, preserving its sanity and physical integrity, avoiding injuries, friction burns due to impact and/or traction. It is a dynamic, elastic, anti-static rope where the harmful effect of the impact of a sudden stop is practically nil, which follows all the requirements of the Federal Law 10.591/02. First and foremost, the animal welfare is taken into account in Team Roping competitions. The evolution of Team Roping competitions is under constant improvement in Brazil and in the world, to which the present invention brings several benefits.
WIRE ROPE
This wire rope is provided with a plurality of strands that are twisted with each other, and the plurality of strands each have a configuration in which a plurality of element wires are twisted with each other. The wire rope is further provided with a single wire that is disposed in a recess section formed on the outer peripheral side of the wire rope by two strands that are adjacent to each other along the peripheral direction of the wire rope. In a transverse cross-section of the wire rope, a portion of the single wire is positioned inside a virtual circumscribed circle of one of the two strands.
HIGH STRENGTH WIRE
Ultra-High-Strength (UHS) wires are suited to high strength wire, strands, cables and rope applications including robotics force transmission and other high-performance mono- and multifilament wire applications. The wires exhibit high strength, low stretch and fatigue durability. Exemplary UHS materials include binary molybdenum-rhenium or tungsten-rhenium alloys with between 20 and 50 wt. % rhenium. These alloys are processed from a moderate strength (<2 GPa) warm-drawn rod to drawn monofilament wire with extreme nanocrystalline grain refinement, high apparent fatigue durability, and ultimate strength levels exceeding 5 GPa in all cases, and up to 6.8 GPa at monofilament diameters ranging from 7 to 100 μm.
