摘要： A method for manufacturing a tire having a sidewall portion provided with a projecting marking is disclosed. A stencil plate for molding the projecting marking is made of a thin metallic plate whose thickness is 0.2 to 0.8 mm and mounted in a recess formed in a sidewall molding surface of the tire vulcanization mold. A concave marking part for molding the projecting marking is formed by press working upon the metallic plate. Edge portions of the stencil plate are turned back. The backward extension H2 of the turnback is substantially the same as the depth of the concave marking part.

摘要： To provide a rubber extruder capable of efficiently removing volatile components in unvulcanized rubber without decreasing productivity of the unvulcanized rubber. The rubber extruder 1 is for extruding the unvulcanized rubber (G) while kneading. It includes a barrel 2 having an input port 5 for introducing the unvulcanized rubber (G) and a discharge port 6 for discharging the unvulcanized rubber (G), a screw 3, which is arranged in the barrel 2, for extruding the unvulcanized rubber (G), and a vent 4 for sucking out air in the barrel 2. The screw 3 has a dam portion 7 which locally controls an extrusion amount of the unvulcanized rubber (G), a first screw portion 8 defined between the input port 5 and the dam portion 7, and a second screw portion 9 defined between the dam portion 7 and the discharge port 6. An effective screw length (L1) of the first screw portion 8 is 50% or more of a total effective screw length (L) of the screw 3.

摘要： A pneumatic tire manufacturing method is provided in which raw cover molding is suitably performed with no, or a minimal amount of, down-stitching in the manufacture of SOT-structure pneumatic tires; also provided is a pneumatic tire. This pneumatic tire manufacturing method involves a first cover molding step for molding a first cover having a sidewall, an inner lining, a ply, beads and a tread-side edge, a tread ring forming step for forming a tread ring having a breaker, a band and a tread center part, a shaping step for pressure-bonding the tread ring and the first cover to mold this to the shape of the raw cover, and a turn-up step for bonding the side wall to the lateral surface of the first cover, wherein the tread-side edge is formed in a position adjacent to the end of the tread center portion in the shaping step, and in the turn-up step, the tread-side edge and the tread center part are bonded together.

摘要： A pneumatic tire manufacturing method is provided in which winding collapse is prevented, there is no possibility of adverse effects on the FV, a current-carrying layer can be formed easily, and down-stitching can be dispensed with or minimized in the manufacture of SOT-structure pneumatic tires having a base-pen structure in the tread. This pneumatic tire manufacturing method involves: a step in which a sidewall, an inner liner, and a ply are bonded on a first molding drum, beads are set, and the tread side part that will form the current-carrying layer is formed on the side wall, forming a first cover; a step in which a breaker and band are bonded on a second molding drum and the tread center part is formed on the band, shaping the tread ring; a step in which the first cover is inserted inside of the tread ring and inflated to bond to the tread ring with pressure; and a step in which the sidewall is bonded to the lateral surface of the first cover, and the tread side part and the tread center part are bonded together.

摘要： A pneumatic tire 1 is provided in a bead portion 4 with a bead core 5 formed of a bead wire 20. The bead core 5 has a wound single bead wire structure formed from turns of the single bead wire 20, and has at least three wire layers 10. Each side face of the bead core 5 has a shape such that it is possible to draw a common tangent 30 to at least two turns of the bead wire 20 appearing in the side face 51 which common tangent is substantially parallel with the tire radial direction. The turns of the bead wire 21 in the 1st wire layer 11 are alternated with the turns of the bead wire 22 in the 2nd wire layer 12 disposed on the outside of the 1st wire layer 11. The 1st wire layer 11 includes a turn 21 having the winding-start end 16 of the bead wire, which turn 21 is positioned between adjacent two turns 22 of the bead wire in the 2nd wire layer 12.
