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 composite wire or thread-based reinforcement is coated with rubber and may be used for reinforcing a finished rubber article, such as a tyre. The reinforcement includes one or more textile or metallic reinforcing wires or threads, and a coating rubber that coats each wire or thread. The coating rubber is formed of a rubber composition that includes at least one diene elastomer, a reinforcing filler, between 10 and 150 phr (parts by weight per hundred parts of elastomer or rubber) of a platy filler, and a crosslinking system. The coating rubber has improved water-barrier properties, thus giving the composite wire or thread-based reinforcement better protection against corrosion or ageing due to penetration of water, for example through tyre tread.

Abstract:
A reinforcing cord of the present invention is a reinforcing cord (10) for rubber reinforcement including a fiber core (11) and a plurality of strands (12) disposed around the fiber core (11). The fiber core (11) is formed of one or a plurality of highly elastic fibers having a tensile elastic modulus of at least 100 GPa. Each of the plurality of strands (12) is formed of a plurality of glass fibers that are primarily twisted, and the plurality of strands (12) are finally twisted to be disposed around the fiber core (11). The direction of the final twist of the plurality of strands is opposite to the direction of the primary twist in each of the plurality of strands (12). The number of final twists of the plurality of strands (12) is 1.0 to 3.0 times/25 mm, and a ratio of the number of primary twists in each of the plurality of strands (12) to the number of final twists of the plurality of strands (12) (the number of primary twists/the number of final twists) is in a range of 1.5 to 2.5.
Abstract:
There are provided an annular concentric stranded bead cord which can realize a reduction in weight while ensuring its strength, a method for manufacturing the same and a vehicle tire.The manufacturing method is a method for manufacturing an annular concentric stranded bead cord by forming a sheath layer by winding spirally a lateral wire round an annular core. After the sheath layer has been formed, the lateral wire is annealed in a pressure-reduced inactive gaseous atmosphere with an annealing quantity which exceeds a heating quantity (temperature×time) which is necessary for vulcanization of a vehicle tire with the annular concentric stranded bead cord embedded in a rubber of the vehicle tire when building the same and is shaped so that “Diameter shaping ratio (%)=H/D×100” becomes 20% or larger and 105% or smaller.
