Abstract: PROBLEM TO BE SOLVED: To provide wave forms different from wave forms of the prior art to a steel filament of a steel structure.SOLUTION: A single steel filament is adapted for the reinforcement of elastomers, and the single steel filament includes one or more steel elements (10). At least one of the steel elements (10) includes a first and a second crimps. The first crimp extends in a plane that is substantially different from the plane of the second crimp. Formation of both crimps can be carried out efficiently by using two pairs of toothed wheels (12, 14) which are not externally driven. The crimps render it possible to obtain single steel filament with an increased penetration of rubber or with an increased elongation at break.

Abstract: PROBLEM TO BE SOLVED: To provide a steel cord for reinforcing a rubber product, used as a reinforcing material of the rubber product such as a tire for a vehicle and an industrial belt, and having an extremely flat shape and fatigue resistance. SOLUTION: The steel cord for reinforcing the rubber product, having a 3+N structure obtained by twisting N (N is 5-13) wires forming sheath side around a core consisting of three wires is regulated so that the core wires 11 may be parallel to each other, and arranged in one nearly linear direction at the cross section of the cord to form the cord cross section into the extremely flat shape, and the core wires 11 may satisfy the requirements in P of from 0.22Pc to 0.43Pc and in d1 of from 1.02d to 1.05d [wherein, P is the pitch (mm) of kink; Pc is a twisting pitch (mm) of the sheath wire; d1 is an apparent outer diameter (mm); and d is a diameter (mm) of the core wire] to facilitate the stretch of the core wire 11 and to enable a tensile load to be dispersed to the core wires 11 and the wires 12 at the sheath side.

Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire that is superior in durability and productivity and that achieves weight reduction.SOLUTION: The pneumatic tire includes a belt comprising at least three belt layers. A steel cord 10 constituting the outermost belt layer has two untwisted core filaments 11, and six sheath filaments 12 are twisted together around a core. An average distance D between the sheath filaments 12, which is in the range of 25-80 μm, is expressed by the following formula: D=[L-6ds{1+(L/p)}]/6 (I) (where L=(π+2)dc+πds). In the formula, dc represents a diameter of the core filament; ds represents a diameter of the sheath filament; and p (mm) represents a twist pitch of the sheath filament 12. Additionally, the belt has a crossover belt layer, and a cord diameter of the steel cord of the crossover belt layer is larger than the minor axis of the steel cord of the outermost belt layer.
