Abstract:
PROBLEM TO BE SOLVED: To provide a steel cord for reinforcing a rubber article; and to provide a pneumatic radial tire having improved durability by using the steel cord for reinforcing the rubber article as a reinforcing material. SOLUTION: The steel cord for reinforcing the rubber article has a 1+6 double twisted structure constituted of one core strand having two- or three-ply layered twist structure, and six sheath strands surrounding the core strand and having two- or three-ply layered twist structures. The whole layered twist directions in the core strand 1 and the twist direction of the sheath strand 4 are the same direction, and the layered twist directions in the sheath strands 4 are the combination of different directions.

Abstract:
Disclosed is a steel wire rope for conveyor belts. The steel wire rope includes a central steel wire, a steel wire layer externally wound on the central steel wire, and a plurality of external steel wire strands. Each external steel wire strand includes a core steel wire and N external steel wires. The central steel wire, the steel wire layer externally wound on the central steel wire, and the plurality of external steel wire strands are wound into a steel wire rope for conveyor belts in one step. The steel wire layer is externally wound on the outer side of the central steel wire, the external steel wire strands are wound to wrap the outer side of the steel wire layer, and the external steel wire strands are in line contact with the steel wire layer.
Abstract:
A cord (1) for a tyre (30) includes a strand (2) of metallic core threads (5) and at least two shells (3,4) of metallic threads (6,7) arranged around the core strand (2); the threads (5,6,7) of the core strand (2) and of the shells (3,4) are helically twisted with the same direction of lay.
