<p>Precise measurement of the entire surface of a green tire is performed during a building process. A laser displacement gauge 10 is provided integrally on a bonding roller 2 for bonding a ribbon to a building drum 2 of a tire building apparatus 1, and the profile of a green tire after bonding the ribbon is measured while the ribbon is bonded. At this time, the displacement gauge 10 is enabled to move in an X-Y plane and rotate in the same plane to change the orientation while the ribbon is bonded, so as to enable measurement of the entire surface of the tire. Then, the resulting data with respect to the Y-axis direction is corrected according to the difference in position between the bonding roller 3 and the laser displacement gauge 10.</p> |
