METHOD AND SYSTEM FOR MANUFACTURING TIRE MEMBER

WIPO Patent Application WO/2023/188641

A1

Provided are a method and a system that enable highly productive manufacture of an elongated tire member formed by joining a plurality of types of constitutive members, through reduction of variation in predetermined quality in the longitudinal direction. A step of conveying a tire member R in a longitudinal direction L by using a conveyor 2, while irradiating, by an X-ray inspection device 3, a predetermined length range C with an X-ray from a surface side of the tire member R to obtain image data D based on X-ray permeability is continuously carried out to obtain the image data D of the predetermined length range C that is continuous in the longitudinal direction L without any gap. The mass of the tire member R and the magnitude of variation in a distribution of a constitutive member M1 formed from unvulcanized rubber having a greater content of a particular component in the longitudinal direction L are calculated by a calculation device 4 on the basis of the color density in each image data D. The variation is reduced by controlling rotating speed of a screw 8s installed inside at least one extruder 8 by a control device 9 on the basis of the magnitude of the variation.
