Patent number: 7578897Abstract: Provided is a rubber member sticking device which prevents a sheet material held from becoming deformed and stretching during a separation operation, thus suppressing loss of energy and eliminating traces of vacuum holes. When an unvulcanized rubber sheet 12 is stuck, the unvulcanized rubber sheet 12 is supported by a separating surface 14A of a flat plate 14 and fitting surfaces 19A of a lifting member 16 without a difference in level being created therebetween. In this state, the unvulcanized rubber sheet 12 is in close contact with the fitting surfaces 19A of the lifting member 16. When the unvulcanized rubber sheet 12 is separated, a hydraulic jack 20 lowers the lifting member 16 to create a difference in level between the separating surface 14A of the flat plate 14 and the fitting surfaces 19A of the lifting member 16 so that the unvulcanized rubber sheet 12 is supported only by the separating surface 14A of the flat plate 14.Type: GrantFiled: February 28, 2003Date of Patent: August 25, 2009Assignee: Bridgestone CorporationInventor: Shoju Suzuki

Publication number: 20090008024Abstract: A green tyre disposed on a toroidal support is introduced into a vulcanisation mould. The mould is closed through axial approaching of a pair of half shells acting against the sidewalls and the tread band of the tyre. Circumferential sectors set to operate against the tyre tread band are maintained spaced apart from the tread band itself during admission of a working fluid designed to press the tyre against the toroidal support. Subsequently the sectors are centripetally approached to cause penetration of forming ridges movable in through slits into the tread band, concurrently with a step of full moulding and vulcanisation of the tyre carried out through admission of steam under pressure into the tyre itself.Type: ApplicationFiled: December 28, 2004Publication date: January 8, 2009Inventors: Maurizio Marchini, Fiorenzo Mariani, Pierangelo Misani

Publication number: 20080305195Abstract: A die rib for a tire mold defines the inlets to vent passages of the mold through the sides of the die ribs so that the vent passages do not open through the contour surface of the mold. In one exemplary configuration, the invention provides a die rib having a vent inlet disposed along at least one side of the die rib. The vent inlet may be disposed along up to 80 percent of the length of the die rib with at least one foot disposed against the contour surface of the tire mold section.Type: ApplicationFiled: June 2, 2008Publication date: December 11, 2008Inventor: Richard E. Coleman

Patent number: 7442335Abstract: A tire press has an upper mold fixedly attached to a top plate. A bottom mold is fixedly attached to a bottom plate. The tire press has a plurality of guide posts adapted to maintain proper alignment of the upper mold and the lower mold as the tire press opens and closes. A plurality of lock rods, which are independent of the guide posts, are positioned about the tire press. Each of the lock rods has a first end and a second end. The lock rods may have an adjustment mechanism positioned on the first end of the lock rods to adjust the various mold heights. Locking means are a part of the tire press, which are adapted to selectively engage the second end of the lock rods. Further, each of the lock rods has cylinder mechanism operatively connected to the locking means. The cylinder mechanism is adapted to force the locking means to the surface of the lock rods. The cylinder mechanism is a hydraulic cylinder having the piston disposed within the chamber.Type: GrantFiled: December 23, 2005Date of Patent: October 28, 2008Inventor: John R. Cole

Patent number: 7435068Abstract: A pneumatic tire production system comprises production lines each including a green tire building station for assembling unvulcanized members of pneumatic tires into green tires. The green tires are vulcanized at a vulcanizing station which includes at least one vulcanizing unit equipped with a plurality of vulcanizing molds. The number of the vulcanizing mold is determined so as to satisfy the vulcanizing capacity which is substantially equivalent to the number of green tires formed at the building station within a predetermined unit time. The system serves to minimize the intermediate stock amount of green tires due to minimized changeover between different types of tires to be alternately produced.Type: GrantFiled: December 29, 2003Date of Patent: October 14, 2008Assignee: Bridgestone CorporationInventors: Masaharu Oku, Keishi Mineo, Shigeru Kaneko, Shigeru Miyazaki, Taizo Ito, Akio Obayashi
