Abstract:
A steel cord (10) adapted for the reinforcement of rubber products, the steel cord (10) comprises a core (12) and three or more outer strands (14) twisted around the core (12) in a cord twisting direction. The outer strands (14) comprise outer filaments (16) twisted in a strand twisting direction which is the same as the cord twisting direction. The outer strands (14) have a wavy form which makes spaces between the core (12) and the outer strands. The steel cord (10) has improvements on elongation at break and impact resistance capacity.
Abstract:
A synthetic rope for an elevator having improved resistance to compression and abrasion is provided and comprises a plurality of strands forming layers of the rope, each strand formed from a plurality of pre-twisted strands made from high modulus synthetic filaments. One or more of the strands or layers of strands may be impregnated with a lubricant, such as polytetrafluoroethylene, to reduce the abrasion among the strands and substrands, and increase the service life of the rope. The exterior of the rope may be covered by a jacket that provides for traction with the drive sheave. An elevator system comprising the claimed rope is also provided.
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/m .

Abstract:
Metal cables of improved fatigue strength, which are particularly suitable for use in an oblique folded ply of metal cables for tire tread reinforcement, comprise a visible outer layer of strands with each strand being formed of at least two elementary wires, the pitch of the strands being less than the pitch of the elementary wires, these two pitches being of the same direction (S or Z).
