Kind Code:

A1

Abstract:

This method for manufacturing pneumatic tires, whereby green tires are formed, comprises: (a) an assembly step in which a laminated body is manufactured by offsetting ends (2a, 2b) in the width direction of an inner liner (2) and ends (3a, 3b) in the width direction of an unvulcanized rubber sheet (3) 50 mm to 500 mm from each other in the width direction, and bonding said inner liner and unvulcanized rubber sheet; (b) a cutting step in which strips (4) are manufactured by cutting the laminated body at a fixed length corresponding to the width of a drum (5); (c) a joining step in which a strip (4) is wound around the entire circumference of the drum (5) in such a manner that the cut surface of the strip is oriented in the circumferential direction of the drum (5), and the inner liner (2) is on the inside, and the positions of the ends (2a, 2b) of the inner liner (2), and the ends (3a, 3b) of the unvulcanized rubber sheet (3) are offset a fixed distance, and the ends are then joined.
