Title:
TIRE VULCANIZING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/183422
Kind Code:
A1
Abstract:
In order to efficiently produce uniformly vulcanized tires especially under conditions in which a mold temperature fluctuates, a tire vulcanizing method is provided which comprises measuring temperatures of an inner surface and an outer surface of a tire until the demolding timing without damaging the tire,and monitoring the vulcanized state of the tire with high accuracy on the basis of the measured temperature data, thereby making it possible to realize an optimum vulcanizing operation for each tire. During vulcanization of a tire G, the temperatures of the inner surface and the outer surface are measured at a plurality of principal portions representing the tire G, and the demolding timing is determined according to an equivalent vulcanizing degree indicating the progress of a crosslinking reaction calculated on the basis of the measured temperature data.
