Abstract
To determine the magnitude of variation in predetermined quality in a longitudinal direction of an elongated tire member formed by bonding a plurality of types of constituent members, X-rays are applied to a predetermined length range of a tire member, which is elongated, from a top surface side of the tire member while conveying the tire member in a longitudinal direction using a conveying device to acquire image data based on X-ray transmittance of the predetermined length range. The image data is input into a calculation device. Based on contrast in the image data, the magnitude of variation in the dimension in the width direction of a constituent member in the longitudinal direction is calculated by the calculation device, the constituent member being formed of unvulcanized rubber having a larger mass and a higher content rate of a specific component in the tire member.
