Abstract:
According to embodiments of the present invention, a stranded conductor is formed in which the occurrence of defects, such as strand unevenness of filaments and outward protrusion of filaments, is inhibited. According to embodiments of the present invention, a stranded conductor (1a) includes soft filaments (2a) stranded together. The soft filaments (2a) include a soft filament made of an aluminum material, disposed along a center (101), and include six soft filaments, twelve soft filaments, and eighteen soft filaments made of an aluminum material, disposed around and concentrically with the center. The filaments are softened filaments that are softened. A lay length (Pa) is from 6.2 times to 15.7 times a conductor diameter of the stranded conductor.
Abstract:

The stainless steel auger braid welding material consists of core wires and several steel tendons, wherein the said welding wire is of a round-bar shape; the said steel tendons are wrapped on the external surface of the said core wire along the axial line and stranded around the circumference of the said core wire, and each steel tendon shall be stranded by winding several fine wires. For the stainless steel auger braid welding material adopted in the invention, its melting rate is fast.
Abstract:
A composite cable or rope is described. The cable or rope has an inner metallic rope or core, consisting of a plurality of metal strands and a plurality of covering layers formed around the inner metallic core. An innovative anchoring and safety system is also described. The system has one or more anchorages, fixed to the roof, in each of which the rope is stably locked by screwing, so as not to create instability problems for people attached to the rope.
Abstract:
Metal cord of K×(L+M) construction. K elementary strands assembled in a helix, with pitch PK, each having a cord with L wire inner layer of diameter d1, and M wire outer layer of diameter d2, in a helix with pitch p2 around the inner layer; with (in mm): 0.10
Abstract:
A method of manufacturing a metal cord with two concentric layers of wires is provided. The cord includes an internal layer of M wires, M having a value from 1 to 4, and an external layer of N wires. The cord is rubberized from within in situ. That is, during manufacture of the cord, the cord is rubberized from inside. According to the method, the internal layer is sheathed with rubber or a rubber compound by passing the internal layer through an extrusion head, and the N wires of the external layer are assembled around the sheathed internal layer to form a two-layer cord rubberized from the inside. The rubber is an unsaturated thermoplastic elastomer that is extruded in a molten state, and preferably is a thermoplastic styrene (TPS) type of thermoplastic elastomer, such as an SBS or an SIS block copolymer, for example.
Abstract:
A steel cord (10) adapted for the reinforcement of elastomeric products comprises a core strand (12) and a layer of outer strands (14) arranged around the core strand (12). The core strand (12) comprises a core and at least a layer arranged around the core. The core further comprises one to three core filaments and the layer further comprises three to nine layer filaments. The core strand (12) has a first wave form and each filament of the outer strands (14) has a second wave form such that the first wave form is substantially different from the second wave form. This allows to guarantee full rubber penetration.
Abstract:
A steel rope safety system includes at least one steel rope having at least one strand, and the at least one rope or at least one strand is compacted. Further, a method is provided for making a steel rope safety system comprising the step of providing at least two wires, the step of stranding the wires thereby forming a strand for a rope and the step of compacting the strand. The steel rope safety system includes a guardrail system having vertical poles and horizontal compacted ropes which are held in place by hooks. The steel rope safety system may include non-round shaped, such as trapezoidal shaped compacted wires. There is likewise provided the use of compacted steel ropes as impact reducing material.
Abstract:
A tire having a radial carcass reinforcement, including at least one layer of reinforcing elements, said tire comprising a crown reinforcement, which is itself covered radially with a tread, said tread being joined to two beads via two sidewalls, wherein at least 85% of the reinforcing elements of at least one layer of the carcass reinforcement are non-wrapped metal cords having in what is called the permeability test a flow rate of less than 20 cm3/min, and in that at least 5% of the reinforcing elements of said at least one layer of the carcass reinforcement are cords comprising at least one strand consisting of textile multifilament yarns.
