Abstract:
Tire for vehicle wheels, comprising metallic reinforcing cords made of a single strand of elementary filaments preformed by sinusoidal waving and wound together. Said metallic cords show a value of the integral of the breaking stress not lower than 5000 J/m3.
Abstract:
A steel cord (10) comprises eight or more strands (12, 14) twisted together. Each of the strands has a substantially same cord twisting direction and a substantially same cord twisting pitch in the steel cord, and each of the strands consists of two to five individual filaments (16, 18) twisted together. Such a multi-strand steel cord can be manufactured without having to twist the individual strands separately and beforehand.

Abstract:
PROBLEM TO BE SOLVED: To provide steel cord for rubber reinforcement enabling the unconventional durability of tire to be attained through improving fatigue resistance of the tire, and to provide a pneumatic radial tire using the cord as reinforcing material. SOLUTION: The steel cord for rubber reinforcement has such a multiply intertwisted structure as to have a central structure and at least one outer layer, wherein multiple strands are intertwisted in the same direction at the same pitch. In the steel cord, the central structure consists of mutually intertwisted two or more strands, wherein each of the strands is made by intertwisting 7 or more filaments. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
Draw tape for cables comprising an elongated flexible element composed of a helical multifilament rope (1) composed of three filaments or strands helically wound about a common longitudinal axis. According to a further characteristic said rope is hammered. Still according to an improvement said rope is externally covered by a jacket (2).
