Abstract:
A strip of tire ply stock is reinforced with steel cords wherein the steel cords are constructed of high strength wire filament having at least a tensile strength of −2000×D+4400 MPa where D is the filament diameter in mm. Tires are constructed with the ply stock in the belt and/or carcass.

Abstract:
A reinforcing structure designed for handling compression stress states when the structure is molded into a composite. The structure, specifically a wrapped cord with metallic filaments contained therein, is suitable for both compression and tension load forces. The reinforcing structure has a core comprising a plurality of essentially straight, nested filaments arranged in parallel, the filaments forming a line of contact with adjacent filaments that extends along the length of the filaments. Wrapped about the core is at least one helically wound wire.
Abstract:
A pneumatic tire comprises a cord-reinforced layer such as carcass, belt, bead reinforcing layer which is made of metallic cords, each metallic cord is made up of six to twelve metallic filaments whose diameter is in a range of from 0.15 to 0.45 mm, the metallic filaments include waved filaments and unwaved filaments, each waved filament is two-dimensionally waved at a wave pitch and wave height before twisted, the wave pitch is in a range of from 5.0 to 35.0 times the diameter of the filament, and the wave height is in a range of from 0.2 to 4.0 times the diameter of the filament, and the metallic filaments are twisted together into the cord at a twist pitch of from 10 to 40 mm so that the two-dimensionally waved filaments are each subjected to a certain rotation around its axial.
Abstract:
A cord for reinforcing a tire formed by shaping a bundle prepared by paralleling a plurality of metallic wires having substantially circular sections in an unstranded state with a binder of a polymer material having a melting point of 50° C. to 200° C. The polymer material is preferably low-density polyethylene or medium-density polyethylene. The diameters of the metallic wires are preferably 0.15 to 0.3 mm.
Abstract:
This invention relates to steel wires and steel cords used as a reinforcement for rubber articles such as pneumatic tire, industrial belt and the like, particularly steel wires and steel cords having an excellent adhesion property to rubber, in which an amount of phosphorus included as an oxide in a surface layer region from a brass plated surface applied to a circumferential face of a wire up to a depth of 5 nm in a radial direction of the wire is controlled to not more than 1.5 atomic %, whereby an excellent adhesion property between steel cord and coating rubber can be provided even when an adhesion promoter conventionally added in a coating rubber composition for the steel cord is reduced or is not added.
Abstract:
The present invention relates to a metallic cord for the reinforcement of elastomers. The cord has (a) a core composed of two filaments, (b) a single filament surrounding said core and (c) a sheath of nine filaments surrounding said core and single filament.

Abstract:
Reinforcement cord for elastomeric products, in particular reinforcement cords, for use in vehicle tires comprising inner filaments (1) and at least one outer filament (2) wound helically around the inner filaments (1), characterised in that at least the outer filament (2) has a flattened cross-section and is so dimensioned and positioned that it substantially co-determines the mechanical characteristics of the reinforcement cord via line-like and/or area contact locations with the inner filaments (1).
Abstract:
A steel cord for reinforcing rubber is made by twisting a plurality of strands each made by twisting a plurality of element wires. The cord and the strands are twisted in the same direction. The product of the twisting ratio of the cord and that of the strands, the elongation coefficient of the cord and other factors are determined so that the rubber penetration and the rigidity and tenacity of the cord will be suitable for the carcass cord of steel radial tire.
