Abrégé
(EN) There are provided a method and a drum for building a tire in which residual air can be effectively removed by enhancing a pressing force of a carcass band to a bead filler in the turning of the carcass band around a bead core, wherein a cylindrical green case is arranged on an outer peripheral side of a building drum, and a central portion of the green case is expansion-deformed in a radial direction while approaching both the bead cores to each other under a restraint of the bead core through the building drum, and the green case is pressed onto an inner peripheral face of a belt-tread band, and thereafter both the end portions of the carcass band are turned around the bead cores so that the carcass band is pushed onto rigid support members disposed at an inner peripheral side of the carcass band together with the bead cores and bead fillers.
(ZH)

用于成型一种通过在将胎体条带围绕胎圈芯卷起时增大在胎体条带与填充胶条之间的压配合力而能够有效地去除残留空气的轮胎的方法和成型鼓，该方法包括以下步骤：将圆柱形未硫化胎体布置到成型鼓的外周边侧上；在由成型鼓约束胎圈芯的情况下使两个胎圈芯相互靠近和移动的同时，使未硫化胎体的中央部分沿径向凸起地变形，以将未硫化胎体压配合到带束层胎面条带的内周面上；以及当使胎体条带的两个端部围绕胎圈芯卷起时，将胎体条带与胎圈芯和填充胶条一起压到设置在胎体条带的内周边侧上的刚性支撑构件上。
