    Abstract: Provided is a steel cord for reinforcing rubber articles which has both rubber penetration and productivity and which allows to reduce the weight of a tire without compromising the strength of the tire when applied to a tire, and a pneumatic tire using the same.The steel cord for reinforcing rubber articles of the present invention is a steel cord for reinforcing rubber articles comprising a core formed by arranging two core filaments in parallel without twisting the filaments together, and six sheath filaments twisted around the core. Letting the diameter of the core filament dc (mm), the diameter of the sheath filament ds (mm) and sheath filament twist pitch p (mm), an average sheath filament interval D represented by the following Formula (I): D=[L−6ds{1+(L/p)2}1/2]/6  (I), (where L=(π+2)dc+πds) is from 25 to 80 μm.

    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.
