20120312455 | PNEUMATIC TIRE MOLDING METHOD AND MOLDING APPARATUS - A pneumatic tire molding method and apparatus enable a side member to be attached to a tire component member set on an external circumferential surface of a rigid inner mold with intimate contact while preventing deformation of the side member surface shape. An annular recess in an annular holder covers an area corresponding to a tire side section of a carcass material on an external circumferential surface of a circular-cylindrically shaped rigid inner mold having substantially the same shape as a profile of an internal circumferential surface of a tire to be manufactured. Air is sucked from a space between the recess and carcass to reduce space pressure. A holding part is arranged inside the recess, has a holding surface having the same shape as a side member surface, and attaches the side member to the reduced pressure area. Remaining tire components are attached to complete a green tire. | 12-13-2012 |
20120312441 | PNEUMATIC RADIAL TIRE FOR USE ON PASSENGER CAR - A pneumatic radial tire for use on passenger cars including two layers of a belt layer formed from steel cords embedded at an angle from 15° to 45° with respect to a tire circumferential direction. The belt layers are formed from steel cords formed from a non-twisted steel monofilament having a diameter from 0.27 mm to 0.45 mm. A belt auxiliary layer formed from steel cords embedded at an angle from 80° to 90° with respect to the tire circumferential direction is provided between a carcass layer and the belt layers. | 12-13-2012 |
20120312438 | PNEUMATIC TIRE - A center rib is formed by two circumferential main grooves. A main inclined groove and an auxiliary inclined groove are formed in the center rib. The main inclined groove is inclined with respect to the tire circumferential direction to become distanced from the tire equatorial plane from a leading side toward a trailing side in a tire rotational direction, a plurality of the main inclined grooves being juxtaposed in the tire circumferential direction and disposed alternately in the tire circumferential direction on both sides of the tire equatorial plane. The auxiliary inclined groove inclines with respect to the tire circumferential direction to become distanced from the tire equatorial plane from the leading side toward the trailing side in the tire rotational direction, a leading end and a trailing end terminating within the center rib while intersecting at least two of the main inclined grooves. | 12-13-2012 |
20120312387 | METHOD AND DEVICE FOR RECOVERING PUNCTURE REPAIR LIQUID - A device for recovering puncture repair liquid includes a tube to be inserted from a tire valve mounted to a wheel up to an inner surface of a tire, a container having a pair of connecting ports for receiving and containing puncture repair liquid recovered from inside the tire, and a connecting hose for connecting between the tire valve and one of the connecting ports. The other connecting port is removably attachable to a pressurized air source. A valve core is detached from a tire valve of a wheel with a tire mounted thereon into which puncture repair liquid has been injected. The tube is inserted into the tire which is filled with air from the pressurized air source that is then detached from the container. Thus, recovery of the puncture repair liquid is efficiently performed using pressure escaping from the tire without cutting out the tire valve. | 12-13-2012 |
20120309867 | TIRE PUNCTURE SEALANT - An object of the present invention is to provide a tire puncture sealant whereby both sealing performance and storage performance can be achieved. A tire puncture sealant is provided that includes a natural rubber latex, an antifreezing agent, and an acrylic emulsion. A mass ratio of a solid content of the natural rubber latex to a solid content of the acrylic emulsion (natural rubber/acrylic resin) is from 50/50 to 15/85. An amount of the antifreezing agent is from 100 to 300 parts by mass per 100 parts by mass of a total of the solid content of the natural rubber latex and the solid content of the acrylic emulsion. The total of the solid content of the natural rubber latex and the solid content of the acrylic emulsion is from 20 to 40 mass % of a total mass of the tire puncture sealant. | 12-06-2012 |
20120305155 | PNEUMATIC TIRE - In a pneumatic tire, center land portions include a circumferential narrow groove extending in the tire circumferential direction so as to partition the center land portions in a tire width direction; a plurality of lug grooves disposed in each region of each of the center land portions partitioned by the circumferential narrow groove, extending in the tire width direction, so as to partition each of the regions of the center land portions in the tire circumferential direction; and a plurality of blocks partitioned by the circumferential narrow groove and the plurality of lug grooves. Blocks of the center land portions include one open sipe extending in the tire width direction so as to partition the blocks in the tire circumferential direction, and three or more closed sipes disposed in each of the regions of each of the blocks partitioned by the open sipe. | 12-06-2012 |
20120299217 | METHOD FOR MANUFACTURING PNEUMATIC TIRE - 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. | 11-29-2012 |
20120298279 | PNEUMATIC TIRE - A pneumatic tire including: a cylindrical annular structure; a 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; a carcass portion provided on at least both sides in a width direction of the cylindrical structure including the annular structure and the rubber layer; and an extending portion that extends from both sides in the width direction of the annular structure farther outward in the width direction than a ground contact edge on the outer side in the width direction of the tread portion, and that is provided in plurality on both sides in the width direction along the circumferential direction of the annular structure. | 11-29-2012 |
20120298274 | PNEUMATIC TIRE - A pneumatic tire has a plurality of recesses provided on the surface of each figures of a first indication portion. The recesses are provided so as to extend in the tire circumferential direction and are aligned side by side with each other in a direction crossing the extending direction. One end side and the other end side in the width direction of each recess are formed by curved surfaces of which a center of curvature is disposed at the outside in the tire width direction. Therefore, gradation of brightness occurs on the curved surface on the each recess. The gradation on the each recess changes depending on the viewing direction or the lighting direction. Therefore, each figure in the first indication portion looks three-dimensionally and can become more conspicuous than the other portions of a side wall. | 11-29-2012 |
