The length of the drawer is measured and cut to a predetermined length by the fixed-size cutting means to form a fixed-size ply.When measuring the ply size, the transfer conveyor is moved from the state where the cut end is positioned on the cutter table. The ply is moved backward a little (predetermined distance) to retreat the ply once, the ply cut end adhered to the cutter table is separated, and then the transfer conveyor is advanced again to measure the length of the ply with a measuring roll.

Therefore, even if the ply tip position is not shifted or wrinkled, the length can be accurately measured even if the ply slides with the transfer conveyor, and a fixed-size ply without variation can be obtained. The sizing ply obtained in this way is transferred from the transfer conveyor at its tip or all over the supply conveyor, and the tip of the sizing ply is stopped at the standby position of the supply conveyor tip. Then
Tire building drum and supply conveyor (and transfer conveyor)
Are simultaneously driven to transfer the tip of the ply onto the drum. The peripheral speed of the drum surface and the speed of the supply conveyor are driven at a constant ratio (for example, the conveyor speed is set to 0.98 to 0.999 with respect to the drum peripheral speed of 1).

Since the sticking and forming operations of 12 are the same, only the ply 10 will be described. First, the tip of the ply 10 fed out onto the first transfer conveyor 3A is positioned on the cutter table 13, and is cut and removed by the fixed-size cutter 15.
Then, in order to cut off the cut end of the ply 10 from the cutter table 13, the first transfer conveyor 3A is moved backward to retract the ply 10 by a predetermined distance (for example, about 30 mm). Do not touch 10).

Therefore, the interlock between the first transfer conveyor 3A and the second transfer conveyor 3B is released, and the second transfer conveyor 3B and the supply conveyor 6 are driven so that the cut fixed-size ply 10 is cut.
A is moved onto the supply conveyor 6, the leading end of the fixed-size ply 10A is positioned at the standby position 32 in FIG. 2, and both conveyors 3, 6 are stopped and put on standby.

In a method of automatically supplying the sizing material to a tire forming drum by sequentially supplying the sizing material to a tire forming drum from a direction orthogonal to the axis thereof and automatically forming the sizing material on the drum, a front roller is transferred after transferring the tip of the sizing material to the drum. By pressing the leading end of the material against the drum, pressing the fixed size material onto the leading end of the supply conveyor by the rear roller, simultaneously driving the drum and the supply conveyor, and applying a constant tension to the fixed size material between the front and rear rollers. Since it is a feature, it is possible to secure the accuracy of the joint amount at the both ends of the fixed size material, and to stabilize the tire quality.
