<P>PROBLEM TO BE SOLVED: To provide a post-cure inflator and method of cooling tire after vulcanization, capable of preventing deterioration of RFV and RRO due to heat shrinkage of a ply by sufficiently cooling the ply in a vulcanization process of the tire in which cooling time is limited and capable of efficiently cooling the tire without need for the large amount of cooling water. <P>SOLUTION: In a post-cure inflator, a sprayer for spraying cooling medium inside the tire, and an air vent for discharging the air inside the tire are provided at a rim. The method of cooling the tire after vulcanization uses the post-cure inflator. The cooing medium is sprayed inside the tire from the sprayer to cool the tire from the inside. The air inside the tire is discharged through an air vent. Thus, the increase in the inner pressure of the tire due to vaporization of the sprayed cooling medium is suppressed, and the inner pressure of the tire is kept constant. <P>COPYRIGHT: (C)2013,JPO&INPIT |
