<p>In building of a green tire by placing bead cores on carcass cords arranged on a support body, the carcass cords are precisely and accurately placed at predetermined positions. The carcass cords (C) are arranged on the entire circumference of a core (21), ends of the carcass cords (C) are bonded to end holding means (30), and the ends are separated outward from the core (21) in the axial direction of the core (21) and held with tensile force applied between each end and the core (21). Each bead core (60) is moved from the outside of the carcass cords (C) toward a bead building section (24) of the core (21) and made to be in contact with the carcass cords (C), whose ends are fixed, to press the carcass cords (C) to the core (21) side. The pressing force push the carcass cords (C) in the direction of movement of the bead core (60), moving the carcass cords (C) toward the core (21) with the tensile force applied. While the carcass cords (C) are sequentially arranged on side faces of the core (21), the bead cores (60) are placed in the bead building section (24) with the carcass cords (C) positioned between the bead cores (60).</p> |
