<p>A method and apparatus for producing an air bladder for safety tire in which poor bonding of a hoop reinforcement layer and damage of a tube can be prevented by bonding the tube and the hoop reinforcement layer without using a press bonding means. The apparatus (1) for producing an air bladder for safety tires comprises a forming drum (2) for holding an air-impermeable toroidal tube (3) fixedly from the inside, a means (5) for carrying a ring-like hoop reinforcement layer (4) onto the outer circumference of the molding drum (2), an air supply means (6) for expanding the tube (3) by filling it with air, and a plurality of restriction means (7, 8) for suppressing expansion of the tube (3) filled with air. The forming drum (2) and the restriction means (7, 8) are united to surround the tube (3) and the hoop reinforcement layer (4). The tube (3) is expanded by filling it with air, and the tube (3) is press bonded to the hoop reinforcement layer (4) with inner pressure, thus forming an air bladder.</p> |
