ABSTRACT:
A rotatably supported annular tire bead is rotated by drive rollers held in contact with the inner circumferential surface of the bead, and during rotation of the bead a tape is fed and stuck onto the inner circumferential surface of the bead. The opposite side edge portions of this tape extending from this bead are stuck onto the opposite side surfaces of the bead by being pinched from the opposite sides by flange portions of the drive rollers and flange members opposed thereto, subsequently the opposite side edge portions of the tape are folded back onto the outer circumferential surface of the bead by means of scraper members, and thus the bead is perfectly covered by the tape. The above-mentioned flange members are fitted around the drive rollers so as to be slidable in the axial direction, and they are biased to reduce the intervals between the flange members and the flange portions of the drive rollers. Furthermore, there is provided expanding means for expanding the above-mentioned intervals.
