Patent ID: 8100678

Claim:
A tire vulcanizing machine for vulcanizing a green tire, comprising: a mold adapted to accommodate a green tire removably; a bladder capable of expansion and contraction and disposed inside the green tire, said bladder having an interior side exposed to a heating/pressurizing medium; a jet section adapted to jet said heating/pressurizing medium for vulcanizing/molding of the green tire to the interior of said bladder, thereby expanding said bladder to press the green tire against said mold; a medium supply path for supplying the heating/pressurizing medium to said jet section; the heating/pressurizing medium being jetted from said jet section into said bladder and having a portion of said heating/pressurizing medium contacted against said interior of said bladder, a holding section for holding an edge portion of said bladder on the interior side of said bladder adjacent to said medium supply path; and a heat insulator disposed so as to suppress the conduction of heat from the heating/pressurizing medium to the holding section, said heat insulator having a jet section-side portion positioned between a portion of the jet section and a portion of the holding section, the heating/pressurizing medium jetted from said jet section through said medium supply path across a portion of said holding section and providing heat for an edge portion of the green tire.
