ABSTRACT:
The shapes of the upper tire bead Bu and the lower tire bead Bl of a green tire G and the axial distance between the tire beads Bu and Bl are corrected in a short work time. The green tire G is placed in horizontal attitude on a green tire support table3provided with a lower tire bead correcting unit10. Radially movable pressing members13included in the lower tire bead correcting unit10are engaged with the inner side of the lower tire bead Bl of the green tire G and stoppers29of the upper tire bead correcting unit20are engaged with the inner side of the upper tire bead Bu of the green tire G placed on the green tire support table3. The pressing members13of the lower tire bead correcting unit10are moved radially outward to shape the lower tire bead Bl into a completely round shape of a predetermined diameter. The stoppers29of the upper tire bead correcting unit20are moved radially outward to shape the upper tire bead Bu into a completely round shape of a predetermined diameter and, at substantially the same time, the upper tire bead correcting unit20or the lower tire bead correcting unit10is moved vertically to adjust the axial distance B between the tire beads Bu and Bl to a predetermined axial bead spacing.
