发明名称 APPARATUS AND METHOD FOR PRODUCING TIRE
摘要 In forming a green tire by arranging a plurality of carcass cords on a support member and disposing bead cores, the carcass cords are precisely and accurately disposed at predetermined positions. A plurality of carcass cords (C) are arranged over the entire circumference of a core (21), and the ends thereof are attached to the end holding means (30) so that the ends are held at positions distant from each other axially outward of the core (21) in a stretched state between the core (21) and themselves. Bead cores (60) are moved from the outside of the carcass cords (C) toward bead molding portions (24) of the core (21), are brought into contact with the carcass cords (C) held at the ends, and are pressed against the core (21). This pressing force presses the carcass cords (C) in the traveling direction of the bead cores (60), displaces them toward the core (21) in a stretched state, sequentially disposes the carcass cords (C) on the side surfaces of the core (21), and disposes the bead cores (60) on the bead molding portions (24) with the carcass cords (C) therebetween.
