    Abstract: A steel cord for reinforcing rubber articles in which sheath wires are not deviated and which has an excellent rubber penetration property and a tire which has an excellent durability using the steel cord is provided.A steel cord for reinforcing rubber articles composed of a core 10 composed of two untwisted steel wires 1 and six sheath wires 2 which are twisted around the core 10 is disclosed. The average of gap distances between the adjacent sheath wires 2 is 24 μm or larger, and the occupancy of the sheath wires 6 disposed around the core 10 with respect to a sheath wire disposition area is 80% or larger. A pneumatic tire in which the steel cord is applied on both a carcass and (a) belt layer(s) or applied on either the carcass or the belt layer(s) is also disclosed.

    Abstract: A metal cord includes at least one preformed elementary metal wire. The metal cord has an elongation at break, measured on the bare cord, higher than or equal to 3%, preferably 4% to 6%; an elongation at break, measured on the rubberized and vulcanized cord, which differs in an amount not higher than or equal to 15%, preferably 2% to 10% with respect to the elongation at break measured on the bare cord; a part load elongation, measured on the bare cord, higher than or equal to 0.4%, preferably 0.5% to 1.5%; a part load elongation, measured on the rubberized and vulcanized cord, which differs in an amount not higher than or equal to 15%, preferably 0.5% to 10%, with respect to the part load elongation measured on the bare cord.

    Abstract: A tire cord having core filaments preformed into a helical configuration while maintaining the core filaments in a parallel, side-by-side relationship. The core filaments are not twisted or stranded together. High tensile strength sheath filaments are also preformed into a flattened helical configuration so that the sheath filaments can be wrapped around the side-by-side core filaments such that the sheath filaments do not put such tension on the core filaments as to cause the core filaments to bunch. The core filaments are maintained in a flat, side-by-side configation so that no voids are formed and rubber can penetrate into the tire cord. The core filaments may number from three to six and the sheath filaments from one to seven. The cross-section of the tire cord is flattened and confined within an oval-shaped outer bound, the oval outer bound being characterized by a major axis and a minor axis. It is desirable that the minor axis be no greater than 60% of the major axis to created the appropriate difference in the bending modulus of the tire cord in the horizontal versus the vertical direction.
