    Abstract: There is provided a steel cord including a plurality of untwisted core filaments of steel aligned in parallel, and a layer of sheath filaments of steel twisted around the core filaments so as to be unevenly distributed around the core filaments, wherein interstices between the filaments are maintained during vulcanization thereby achieving improved rubber penetration (sufficiently adhering rubber to the core filaments). Since the cross sectional length of the steel cord 10 is greater than the minimum cross sectional length, interstices A are maintained between sheath filaments 14 under the tension and pressure p of the surrounding rubber 16 applied to the steel cord 10 during vulcanization. Rubber 16 penetrates into the steel cord 10 through the interstices A, and sufficiently adhere to core filaments 12 to achieve high rubber penetration.

Each of the carcass cords comprises a number nullnnull of steel filaments each having a diameter (d) of from 0.17 to 0.40 mm. The steel filaments are twisted together to have a null1nullnnull bundle-twist structure or an interlace-twist structure. In a vicinity of the maximum tire section width point P of each of the sidewall portions, a sectional shape coefficient S of each carcass cord is set in a range of from 0.5 to 0.9, wherein the sectional shape coefficient S is (d2nulln)/(L1nullL2), nullnnull is the number of the filaments, nulldnull is the average of the diameters of the filaments, nullL1null is the largest measure of distance between two extremities of the cord which occurs in a direction in a cross section of the cord, and nullL2null is the measure of distance between two extremities of the cord in a direction perpendicular to the above-mentioned direction.

    Abstract: A method for using a bunching type twisting machine to manufacture a steel cord made up of one core filament having a continuous wavy form and five to eight sheath filaments not having a wavy form disposed around the core filament, the cross-sectional shape of the cord forming an ellipse whose orientation is substantially constant in the length direction of the cord. After a core filament is preformed with a helical wavy form of a smaller pitch than the cord twisting pitch, this is squashed to form a flat helical core filament at a stage before it is twisted together with sheath filaments, and then sheath filaments are twisted around this flat helical core filament to make an intermediate product cord and this intermediate product cord is then squashed and thereby flattened before being taken up on a reel.
