【０００２】
【従来の技術】
従来、タイヤの成形工程において、タイヤ成形機の成形ドラム上でタイヤ構成材料としてのシート状の成形材料（例えば、カーカス材料や、インナーライナー等）を複数枚重ね合わせて貼付ける場合、成形材料の供給装置と成形ドラムとの間に、転送ロールを介在させて成形材料を成形ドラム上へ移送して貼合わせる方法が行われている。

As a whole, two sets are installed on the outer side of each other in parallel and opposed to each other, and are moved alternately to the four sets of tire molding machine units 17a and 17b.
[0024]
When the transfer roll 25 moves to a predetermined position and stops, the band forming drum 12 of each tire molding machine unit 17a, 17b is turned 90 ° to a position parallel to the transfer roll 25, and the band forming drum 12 is moved to the transfer roll 25. The layered molding materials Wx and Wy wound around the peripheral surface of the transfer roll 25 are pasted on the band forming drum 12 while abutting and rotating the band forming drum 12.
[0025]
In the tire molding machine units 17a and 17b, as described in the first embodiment, the molding material X such as a side tread is attached to the band molding body at a predetermined position, and then the molding materials Wx, Wy, and X are transferred to the band. It is gripped by the device 15 and transferred to the shaping drum 13.
That is, in the band forming drum 12, the side tread is pasted before the carcass material and the inner liner material are pasted.
[0026]
On the other hand, in the belt forming drum 14, a molding material Wy such as a belt and a molding material X such as a side tread are molded and transferred to the shaping drum 13 by the belt transfer device 16, and the shaped molding materials Wx, Wy, and X are formed. The tire is molded by being attached.
Since other configurations and operations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.
[0027]
In the second embodiment, as a whole, four sets of tire molding machine units 17a and 17b are installed in parallel and at opposite directions with a predetermined interval, and two sets of opposing tire molding machine units 17a are respectively provided. , 17b, a set of molding material supply devices 21a, 21b that supply two types of molding materials in parallel with the axis P-P are installed linearly, so that a plurality of tire molding operations can be performed in a narrow space. Can be performed efficiently.
[0028]
Further, two or more types of tires having the same inch size and different drum width sizes can be produced, and the tire productivity can be improved.
[0029]
【The invention's effect】
Since the present invention is configured so that the molding material can be supplied to the molding drums of a plurality of sets of tire molding machine units by one set of molding material supply devices as described above, productivity can be improved in a narrow space. In addition, the equipment cost can be reduced, and two or more types of tires having the same inch size and different drum width sizes can be produced, and the productivity of the tire can be improved.
