が一致するように、予め巻付はドラムの周長に対応させ
た長さにタイヤ構成材料を前工程で切断している。Conventionally, in a tire molding machine, tire materials such as tread members are wound around a drum, and when the tire is wound, the seams of the end portions of the tire constituent materials are aligned. In the winding process, the tire constituent material is cut in advance to a length that corresponds to the circumferential length of the drum.

な状態のタイヤ構成材料を巻付はドラムに巻付けた場合
には、端末部の合わせ目部分に口開きが発生ずる。However, even if the tire constituent material extruded from the extruder is cut into a predetermined length, due to the nature of the rubber material, the wrapping will shrink slightly when it is wrapped around the drum, so the tire structure in this state When the material is wound around a drum, an opening occurs at the seam of the end portion.

巻付はドラムへタイヤ構成材料を供給している。For this reason, in the past, when wrapping around a drum, the winding was based on the assumption that the length of the tire component material would be shorter than the set length. The winding speed is set to a predetermined value, and the tire constituent material is supplied to the drum.

とが出来ないと言う問題があった。However, in reality, when the tire constituent materials placed on the conveyor are wrapped by the drum,
The winding will slip on the conveying device due to force, and for this reason, the circumferential speed ratio of the drum and the correction rate of the conveying speed of the actual conveying device are different, making it difficult to properly correct the winding. However, there was a problem in that the end portions of the tire constituent materials could not be laminated with high accuracy.

The general feeding device 1 is raised by a lifting means (not shown), and the winding drum 4 is moved according to the measured length l of the tire component.
The tire constituent material W is rolled up and conveyed to the drum 4 side at a set speed ratio between the roller and the conveying device 1. At this time, both side edges of the tire constituent material W are connected to a pair of gripping means 7 installed at both ends of each plate 3a and plate-shaped cams 6a, 6.
The windings are sequentially conveyed to the drum 4 side while being gripped by b. That is, as shown in FIG. 9(a), the clamp claws 10 of the gripping means 7 provided on each plate 3a, when the tire constituent material W is placed on the plate 3a on the rear side of the conveying device 1, At that position, it is in a standby state, and when the two chain chains 3 are driven to rotate from this state as shown in FIG. Plate-shaped cams 6a, 6b
By sequentially coming into contact with the tire components 14W, both side edges of the tire component 14W are gripped. In addition, FIGS. 9(a) to 9(e)

。At this time, since the rollers 13 that were in contact with the top surfaces Z of the plate-shaped cams 6a and 6b move toward the inclined surface , the clamped state is released, and the rotating drum 4 wraps the windings one after another with a predetermined tension, and at the same time, the both side edges of the tire constituent material W are released one after another, as shown in FIG. d). Further, the clamp claw 10 that has released the clamp is reversed downward and becomes in a standby state, and in this way, as shown in FIG. The same unwinding operation is performed until the winding of the constituent material W is completed.

とが出来るのである。In this way, the winding is carried out on the drum 4 until just before it is wrapped around the clamp claws 10 of the gripping means 7.
Since the tire component material W is clamped by the drum 4, there is no possibility that only a part of the tire constituent material W is stretched and stretched, and the tension is always uniform and the winding is supplied in a state corresponding to the circumference of the drum 4. The pasting part Q of the part is shown in Fig. 9(e).
As shown in the figure, it is possible to bond with high precision without opening the mesh.
