摘要：
A steel cord comprises a core of three or more filaments bundled without twisting and a sheath of at least one layer comprised of plural filaments wound around the core, wherein all core filaments are arranged in a given rectangle at any section in its longitudinal direction. Such steel cords are used in a belt of a pneumatic tire. And also, these cords are produced by a tubular-type twisting machine having a specified structure.
