## Abstract

A vulcanization apparatus provided with a vulcanization vessel for vulcanizing a green tire and a suction line for sucking out gas from inside the vulcanization vessel after the vulcanization vessel has been opened. Accordingly, oily smoke generated when vulcanized rubber has been removed from a bladder and an inner wall of a mold can be more efficiently discharged than in cases in which gas inside a vulcanization vessel is sucked out and additional air is introduced into the vulcanization vessel only prior to opening the vulcanization vessel.

## Claims

### Claim 1

A vulcanization apparatus, comprising:
a vulcanization vessel for vulcanizing a green tire supported by a bladder to obtain a vulcanized tire; and
a suction device configured to suck out gas from a space surrounding an outer periphery of the bladder that is inside the vulcanization vessel after the vulcanization vessel has been opened and the vulcanized tire is separated from the bladder, wherein the suction device sucks out the gas from a central axis side of a vulcanized tire.

### Claim 2 (depends on 1)

The vulcanization apparatus of claim 1, wherein the vulcanization vessel comprises a controller for controlling the suction device so as to start sucking out gas after the vulcanization vessel has been opened.

### Claim 3 (depends on 1)

The vulcanization apparatus of claim 1, wherein:
the vulcanization vessel comprises a hood section provided at least at an upper portion of the vulcanization vessel and covering from an outside at least a portion of the vulcanization vessel; and
the suction device sucks out gas that is inside the hood section.

### Claim 4 (depends on 1)

The vulcanization apparatus of claim 1, wherein:
the vulcanization vessel comprises a mounting section; and
an air-curtain forming section is provided to the mounting section to partition the inside of the vulcanization vessel from an external space using an air-curtain when the vulcanization vessel has been opened.
