Abstract
A bead wire manufacturing method/apparatus includes a descaling step/device for removing oxide on the surface of a wire rod, a coating liquid adhesion step/device for adhering a coating liquid to the wire rod, wiredrawing steps/devices for performing area reduction workings on the wire rod, and a bluing step/device for bluing the wire rod having been raised to a high temperature through the area reduction workings, in a temperature range of 350° C. to 480° C. Thus, the wire rod having been raised to a high temperature through wiredrawing is blued without being cooled down to effectively utilize the temperature retained therein, so that the method/apparatus is little in energy loss.
