    Abstract: The present invention relates to a single wire steel cord for reinforcing rubber of a pneumatic tire having improved strength and adhesion to rubber and, more particularly, to a single wire steel cord which includes waveform regions having at least one waveform and non-waveform regions. The single wire steel cord has a high strength characteristic. Accordingly, the amount of steel cord is significantly reduced during manufacturing of a tire. As a result, the weight of the tire is reduced and manufacturing cost is lowered due to a simplified manufacturing process.

    Abstract: A steel cord (200) is described that is simple and cost effective to produce while solving some particular problems for the reinforcement of elastomer belts such as timing belts or the like. The cord (200) is a single lay cord that comprises a core filament (202), around which a first layer and a second layer of filaments (204, 210, 212) is twisted, all filaments being twisted with the same lay length and direction. By appropriate choice of the lay length, the core filament diameter and the filament diameters of the first layer—the latter being larger or equal to the former—an aggregate gap can form in which intermittently a filament (210′) of the second layer gets entrained. This aggregate gap must be between 40 and 70% of the core filament diameter in order to obtain the desired effect of having a core filament (202) that is deformed with the same lay length and direction as the other filaments (204,210,212). A deformed core filament (202) suppresses the effect of core filament migration. In addition the exceptional rough aspect of the cord (200) leads to good mechanical anchorage in the elastomer. Also the load exerted on the cord (200) is better distributed over all filaments. The use of the cord is not limited to timing belts: an advantageous use of the cord in tyres, hoses, hoisting belts, drive belts and reinforcing strips is anticipated.

    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.
