TIRE VULCANIZING APPARATUS AND A VULCANIZING METHOD, CAPABLE OF IMPROVING ECONOMIC EFFICIENCY BY VULCANIZING TWO TIRES BY A SYSTEM COMMON TO TWO CENTER MECHANISMS

摘要

PURPOSE: A tire vulcanizing apparatus and a vulcanizing method are provided to time for vulcanizing tires as a bladder is rapidly heated and high temperature nitrogen gas is used in the early stage of vulcanizing.;CONSTITUTION: A tire vulcanizing apparatus(1) comprises a lower mold(2), an upper mold(3), and central units. The central units comprise bladders(B). Nitrogen gas heated by a first heating device(11) flows into the bladders. The nitrogen gas discharged from the bladders is used for vulcanization, and heated again by a second heating device(31). The nitrogen gas heated by the second heating device is supplied to the bladder positioned at the lower side in a circulation direction of the nitrogen gas.;COPYRIGHT KIPO 2013
