接着を行う。The tire forming drum 1 is used to assemble the inner liner, carcass, sidewall, bead, and belt tread structure according to a predetermined procedure, and is also known as a single-stage drum.
This is as shown in Japanese Patent No. 208233 and the like. The belt conveying device 2 has expandable and contractible segments that surround the belt tread structure assembled on the belt forming drum 3 from the outside and grip the outer surface of the belt tread partially or over the entire area. The expansion/contraction mechanism is mounted on a movable truck, which moves between the tire forming drum position [Y, the belt forming drum position X, and the standby position 7]. For example, they are known from Japanese Patent Publication No. 52-1951 and Japanese Patent Publication No. 50-2625. The stitcher 8 is preferably equipped with several rotatable rollers, which are pressed against the rotating tire by known means to bond the materials together.

。Following the above, the belt conveyor 2 moves to the belt forming drum position X to receive and pick up the belt dread structure, and at the same time the stitcher 8 moves to the second standby position U and enters the tire forming drum position Y. Avoid interference with the belt conveying device 2. Belt tread 9 structure and tire forming drum 1
After the belt conveyance device 2 has been transferred to the standby position (2), the belt conveying device 2 returns to its standby position (3). The belt conveying device 2 moves from the tire forming drum position Y.
At the same time as the stitcher 8 starts moving to the standby position ■, it enters the tire forming drum position Y, stitches the tire, grips the completed tire, and then returns to the second standby position with the completed tire. Move to. When the tire is removed in this position, the stitcher returns to its first standby position. In this way, tires are successively molded.
従って、このようなタイヤ成形機の構成によると、ビー
