A triangular-shaped filler rubber is held in an upright posture to be wound around an outer peripheral surface of a bead core supported by a rotary support body, and in joining a leading end and a trailing end of the filler rubber cut to a predetermined length, the neighborhood of the leading end and the neighborhood of the trailing end, respectively, are interposed by first and second interposing means, and one of the interposing means is displaced toward the other from a state, in which the leading end and the trailing end are opposed to each other whereby end surfaces of the leading end and the trailing end are butted against each other.
