PROBLEM TO BE SOLVED: To approximately evenly heat a rigid core 10 and a green tire G. SOLUTION: When a gas heated by a heating means 48 is fed to the heating chamber 16 of the rigid core 10 from a gas feeding means 43 through a feeding passage 45, a rotating means 55 is installed in the middle of the feeding passage 45, and the heated gas is rotated into an eddy form by the rotating means 55. As a result, the heated gas is sufficiently agitated in the feeding passage 45 on the way from the rotating means 55 to the heating chamber 16, and the temperature distribution and the speed distribution of the heated gas become approximately uniform. Thus, the rigid core 10 and the green tire G are approximately uniformly heated. COPYRIGHT: (C)2008,JPO&INPIT |
