Patent ID: 7387697

Claim:
A method for turning up a tire structure member, wherein a pair of beads are supported by a tire building drum from radially inside, and substantially cylindrical turn-up portions of the tire structure member located on axially outside of the beads are turned around the beads to extend along a main body portion of the tire structure member located between the beads and having a substantially semicircular cross-section, with an apparatus including a plurality of turn-up arms spaced from each other in a peripheral direction and arranged on both outside of the tire building drum in the axial direction, said turn-up arms each being adapted to swing in the radial direction around a base end spaced from the bead on a plane including the center axis of the tire building drum, and further including turn-up roller rotatably supported by tip ends of the turn-up arms, wherein the turn-up arms are moved synchronously by a moving means axially inward, with said turn-up rollers maintained in contact with the turn-up portion, while said turn-up arms are swung synchronously by a swinging means radially outward so that the turn-up portions are turned around the bead, wherein said moving means comprises an inner slider which is movable in the axial direction, and said swinging means comprises an outer slider slidably fitted in the inner slider and overlapped with the inner slider at least at its axially inner end, a plurality of links each having an inner end connected to the inner slider and an outer end rotatably connected to a center part in the longitudinal direction of each turn-up arm, and a moving mechanism for axially moving the outer slider relative to the inner slider.
