摘要： Steel cord is manufactured by: forming a plurality of bends, per filament length equivalent to one twist pitch, on each of filaments which constitute an outer layer sheath, with the filament length equivalent to one twist pitch being a cycle; twisting these filaments while the bends belonging to the same phase are aligned in a cord axial direction; and subjecting cord side surfaces to compression processing. As a result, flat side surface portions are formed, in which a plurality of filaments forming the outer layer sheath are positioned substantially in the same plane. The steel cord thus formed is used in reinforcement plies for pneumatic radial tires such that the reinforcement plies are laminated in a manner in which the flat side surface portions are mutually parallel.

摘要： A method for producing a steel cord from 3 to 6 steel filaments on which a coating is applied to retain the adhesion to a rubber, the steel cord being destined for use to reinforce a rubber product having a flat section, comprising the following steps of preforming steel filaments at a ratio of more than 120% by twisting them together to form an open-structure steel cord; and passing the steel cord through a flattening apparatus provided at each of outlet and inlet thereof with a roller having a groove formed in the center of the circumference thereof, and between the inlet and outlet rollers with at least a roller of which the circumferential surface is flat, to repeatedly bend the steel cord vertically or horizontally.
