Abstract:
An object of the present invention is to make it possible to provide a cord, in particular, a cord for reinforcing a rubber article in which rubber permeation properties are improved by coating filaments as constituents of the cord with rubber in a reliable and stable manner. The cord of the present invention is produced by, when the metal filament is guided to an extruder and extruded together with rubber from a mouthpiece of the extruder so that the metal filament is coated with the rubber, juxtaposing plural metal filaments in the mouthpiece and extruding the metal filaments together with rubber.
