PROBLEM TO BE SOLVED: To provide a method for production of a steel cord for reinforcing rubber articles, by which a plurality of untwisted core wires are parallelly arranged stably in the longitudinal direction without overlapping, when producing the steel cord for reinforcing rubber articles having untwisted parallel core wires. SOLUTION: The method produces a steel cord for reinforcing rubber articles by using a buncher twister, which cord has a core provided by arranging a plurality of core wires parallelly without twisting and a plurality of sheath wires twisted around the core, and has a cord having a cross-section of almost oval. The core and the sheath wires are twisted to be the final twisted cord 1, and, soon after removing the twist of the final twisted cord 1 by an over twister 11, the final twisted cord without twist is processed through three or more flat rolls 12 having a flat contact surface with the cord.
