    Abstract: The present invention provides a metallic cord for reinforcing a tire moldable in a tire manufacturing step without complicating operations and keeping strength by reducing rusting and an excellent pneumatic tire employing the metallic cord.The inventive metallic cord for reinforcing a tire is formed by shaping a bundle prepared by paralleling a plurality of metallic wires having substantially circular sections in an unstranded state with a binder of a polymer material having a melting point of 50° C. to 200° C. The polymer material is preferably low-density polyethylene or medium-density polyethylene. The diameters of the metallic wires are preferably 0.15 to 0.3 mm.

    Abstract: A tire cord having core filaments (10) performed into a helical configuration while maintaining the core filaments (10) in a parallel, side-by-side relationship. The core filaments (10) are not twisted or stranded together. High tensile strength sheath filaments (11) are also performed into a flattened helical configuration so that the sheath filaments (11) can be wrapped around the side-by-side core filaments such that the sheath filaments (11) do not put such tension on the core filaments (10) as to cause the core filaments (10) to bunch. The core filaments (10) are maintained in a flat side-by-side configuration so that no voids are formed and rubber can penetrate into the tire cord. The core filaments (10) may number from three to six and the sheath filaments (11) from one to seven. The cross-section of the tire cord is flattened and confined within an oval-shaped outer bound (21), the oval outer bound (21) 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 create the appropriate difference in the bending modulus of the tire cord in the horizontal versus the vertical direction.

    Abstract: Reinforcement cord for elastomeric products, in particular reinforcement cords, for use in vehicle tires comprising inner filaments (1) and at least one outer filament (2) wound helically around the inner filaments (1), characterised in that at least the outer filament (2) has a flattened cross-section and is so dimensioned and positioned that it substantially co-determines the mechanical characteristics of the reinforcement cord via line-like and/or area contact locations with the inner filaments (1).
