Abstract:
1. A method of manufacturing a pneumatic tire, comprising the steps of: mounting a cylindrical body ply on a cylindrical surface of a tire forming apparatus; setting annular beads on both axial end portions of said cylindrical body ply; enlarging the diameter of an axial intermediate portion of said cylindrical body ply while narrowing the spacing between both axial ends of said cylindrical body ply; and moving bending members of the tire forming apparatus, said bending members being formed of rigid bodies, wherein said bending members are moved linearly and radially outward relative to the axis of said body ply to bend said both axial end portions of said body ply by said bending members, so that bent portions of said body ply wrap around the corresponding beads; and using pressing members of said tire forming apparatus to press said axial end portions, on which said beads are disposed, radially outward relative to the axis of said cylindrical body ply, prior to bending said both axial end portions of said body ply.
