Abstract
A steel cord for the reinforcement of elastomer products such as elevator belts, conveyor belts, synchronous or timing belts or hoses or tyres is presented. The steel cord comprises strands and monofilaments made of steel filaments. The strands themselves are also made of steel filaments twisted together. The strands form the outer layer of the steel cord. The monofilaments are twisted into the cord with the same lay length and direction as the strands and are positioned in the valleys between the strands on the radial outer side of the steel cord. The steel cord has the advantage that it has a better fill factor and a rounder aspect. Furthermore the monofilaments may act as an early wear indicator of the elastomer product.
Claims16
A steel cord comprising strands and monofilaments made of steel, wherein said strands comprise strand filaments made of steel twisted together with a strand lay length and direction, wherein said strands are twisted together with a cord lay and direction, said strands forming the outer layer of said steel cord,
- wherein said monofilaments are twisted with the cord lay and direction and fill valleys between adjacent strands on the radial outer side of said outer layer of said steel cord, and wherein said monofilaments have a monofilament tensile strength, said monofilament strength being lower than the tensile strength of the strand filaments closest to said monofilaments.
