<p>A laminate (4) is produced by bonding a thin-film inner liner (1) having gas-barrier properties to an unvulcanized adjacent rubber sheet (3) through an adhesive layer (2) so that the width-direction edges of the liner (1) and sheet (3) are trued up and that the positions of the length-direction edges of the liner (1) have been shifted in an extension direction for the liner (1) and sheet (3) from the positions of the length-direction edges of the sheet (3). The laminate (4) is wound around the whole periphery of a forming die so that the thin-film inner liner (1) faces inward. The winding is conducted in the following manner. That protrudent part of the unvulcanized adjacent rubber sheet (3) which protrudes from the film inner liner (1) is used as part of a winding-on-die initiation end part (4a) of the laminate. The winding of the laminate (4) is started while keeping the protrudent part adherent to the surface of the forming die. That winding-on-die termination end part (4b) of the laminate (4) is inserted inside the winding-on-die initiation end part (4a) of the laminate (4). The end parts of the thin-film inner liner (1) are bonded to each other and the end parts of the unvulcanized adjacent rubber sheet (3) are bonded to each other, in a lap or butt joint arrangement.</p> |
