摘要： The shapes of the upper tire bead Bu and the lower tire bead Bl of a green tire G and the axial distance between the tire beads Bu and Bl are corrected in a short work time. The green tire G is placed in horizontal attitude on a green tire support table 3 provided with a lower tire bead correcting unit 10. Radially movable pressing members 13 included in the lower tire bead correcting unit 10 are engaged with the inner side of the lower tire bead Bl of the green tire G and stoppers 29 of the upper tire bead correcting unit 20 are engaged with the inner side of the upper tire bead Bu of the green tire G placed on the green tire support table 3. The pressing members 13 of the lower tire bead correcting unit 10 are moved radially outward to shape the lower tire bead Bl into a completely round shape of a predetermined diameter. The stoppers 29 of the upper tire bead correcting unit 20 are moved radially outward to shape the upper tire bead Bu into a completely round shape of a predetermined diameter and, at substantially the same time, the upper tire bead correcting unit 20 or the lower tire bead correcting unit 10 is moved vertically to adjust the axial distance B between the tire beads Bu and Bl to a predetermined axial bead spacing.
摘要翻译：在较短的工作时间内校正了生胎轮胎G的上胎圈胎圈B1和下轮胎胎圈B1的形状以及轮胎胎圈Bu和B1之间的轴向距离。生轮胎G在设置有下胎圈修正单元10的生胎轮3上呈水平姿态。下轮胎胎圈校正单元10中包括的径向移动按压构件13与下轮胎胎圈校正单元10的内侧接合生轮胎G的胎圈B1和上轮胎胎圈校正单元20的止动件29与放置在生胎轮3上的生胎轮胎G的上轮胎胎圈的内侧接合。下轮胎胎圈校正单元10径向向外移动，以使下轮胎胎圈B1成为预定直径的完全圆形。上胎圈校正单元20的止动件29径向向外移动，以使上轮胎胎圈Bu形成为预定直径的完全圆形，并且与此同时，上轮胎胎圈校正单元20或下轮胎珠校正单元10垂直移动以将轮胎胎圈Bu和B1之间的轴向距离B调整到预定的轴向间隔。
