ABSTRACT:
The method for molding a bead portion for a green tire includes a bead core supporting step for supporting the bead core through a carcass ply upon expanding a diameter of a bead core supporter including a seating surface for supporting a radially inner surface of the bead core. Since the bead core supporter comprises an outer piece outside of the seating surface in a tire axial direction that rises up towards outside in the radial direction with a clearance between the same and the bead core, that is larger than the thickness of the carcass ply, it is possible to flip a carcass outer region up, that is outside in the tire axial direction than a sandwiched region of the carcass ply, sandwiched and held between the seating surface and the bead core, and to deform the carcass outer region into an outer inclined piece that is inclined and extended towards radially outside without including any partially bent portions. It further includes a curving step of pressing the outer inclined piece inward in the tire axial direction by using a ply winding ring for curving the same towards the outside surface and the radially outer surface of the bead core, and a pressing step of pressing a tip end portion of the curved outer inclined piece towards the radially outer surface of the bead core by using a pressing roller.
