ABSTRACT:
A cylindrical body ply is mounted around a cylindrical bladder, and annular beads are set on both axial end portions of the body ply. In this state, while the spacing between both axial ends of the body ply is narrowed, an axial intermediate portion of the body ply is increased in diameter by the bladder. Subsequently, bending members formed of rigid bodies are radially moved from the inside to the outside of the body ply to bend both axial end portions of the body ply by the bending members. The bent portions of the body ply wrap around corresponding beads. With the use of the body ply manufactured in this way in a tire, the resulting tire can be reduced in the manufacturing cost and weight.
