Abstract: A cylindrical body is formed by mounting a carcass to the outer periphery of a film formed of a thermoplastic resin or a thermoplastic resin elastomer composition. A molded body is formed by fitting bead rings on opposite width direction ends of the cylindrical body, and the molded body is sucked on a transfer mold's inner periphery. After a rigid inner mold is inserted into the molded body, suction stops and the molded body is transferred to the inner mold's outer periphery. Opposite carcass ends in a width direction are turned up on the inner mold, while other tire members are stacked on the molded body's outer periphery to mold a green tire. The tire and inner mold are placed in disposed inside a heated curing mold and the film is inflated to cure the tire and bond the film to the inner peripheral tire surface to form an inner layer.

Abstract: A green tire of a pneumatic tire, including a cylindrical annular structure, an unvulcanized rubber layer, which will become a tread portion, provided along a circumferential direction of the annular structure on an outer side of the annular structure, and a carcass portion including fibers covered with rubber, provided on at least both sides in the width direction of a cylindrical structure including the annular structure and the unvulcanized rubber layer, is disposed in a vulcanization mold. The vulcanization mold is split into the side plates and the sector at a position on the inner side in the width direction of the annular structure. Next, the bladder inside the green tire is pressurized after closing the side plates and prior to closing the sector. Then the sector is closed and vulcanization is started.

Abstract: Provided is a compact casting apparatus capable of producing a high-quality casted product. While the internal pressures of a mold and a hopper are directly reduced by depressurizing means through a pipe and a branch pipe, the mold and the hopper are gradually tilted to fill the mold with a molten metal accommodated in the hopper. After the filling is completed, an open-close gate closes a runner. The molten metal is solidified with only the mold being directly pressured by pressurizing means through the pipe.

Abstract: A vulcanizing mold manufacturing method, and a tire vulcanizing mold are disclosed. Tubular bodies each formed by oppositely arranging the inner peripheral surfaces of both end portions of a plate-shaped body are each arranged so that the gap between both opposite end portions thereof is narrowed and that the tips of both end portions come in contact with the surface of the plaster mold, by inserting and fitting both opposite end portions into a fitting portion of a plate-shaped metal fitting protruding from the surface of the plaster mold. Molten metal is poured over the surface of the plaster mold to embed the tubular body in a mold while exposing the tips of both opposite end portions at the tire molding surface of the mold. The metal fitting is removed from the mold, so that a mold having a small gap between both opposite end portions is manufactured.
