Next, in the above example, tire constituent materials 14 to 16
A series of operations for supplying and pasting the tire to the drum 2 of the tire molding machine will be explained.

Initially, each tray 40 to 42 and movable frames 84 to 86 are in the retreat position, the tire forming drum 2 is stopped, and the inner liner 14.1 ply cord 1
The 5- and 2-ply cords 16 are each let out, and their tips are positioned below the vacuum pads 102, 110 at the front end of each tray 40-42.

Therefore, by the forward movement of the vacuum pad 102,
The cutting start end of the inner liner 14 is held by suction, and then, at the same time as the vacuum pad 102 retreats, the tray 40 advances and descends together with the inner liner 14, and is stopped as close as possible to the tire building drum 2 so as not to contact it. Subsequently, the movable frame 84 advances (descends) to position the inner liner 14 on the tire building drum 2, and after the vacuum band 102 advances and presses the tire building drum 2, it releases the adsorption and retreats.

Subsequently, the pressure roll 50 of the material pressure bonding means 48 is lowered by the operation of the pressure cylinder 53, and the inner liner 14 is
The cut start end of the inner liner is pressed onto the tire building drum 2, and as the tire building drum 2 rotates, the inner liner 14 is fed out and is affixed and crimped by the pressure roll 50. When the tire forming drum 2 is fed out by a length equal to the int amount, the tire forming drum 2 is stopped, and the inner liner 14 on the tray 40 is cut diagonally by the real knife 59 of the material cutting means 55.

The tire building drum 2 rotates again, and the cut end of the inner liner 14 is pressed by the pressure roll 50, and is overlamp jointed with the already pressure-bonded cut start.

Further, the tire building drum 2 rotates, and when the starting end of the adhesion of the next 1-ply cord 15 reaches a predetermined position, the tire building drum 2 stops. On the other hand, the tray 40 and the movable frame 84 move backward, and the air motor 22 of the material support and feeding means 11 is started to wind up the inner liner 14 by a predetermined amount so that no excess slack is generated. One application crimping cycle of 14 is completed.

Note that if meandering occurs during the supply of the inner liner 14, this is detected by a photoelectric detection means (not shown),
Centering is performed by moving one end of the centering roller shaft 46A of the support roller 46 in either the front or rear direction, and the inner liner 14 is accurately supplied.

Simultaneously with the completion of the supply and pasting of the inner liner 14, the 1-ply cord 15 is fed onto the tire building drum 2 by the advancement of the tray 41 in the same manner as the inner liner 14, and after one turn by the rotation of the tire building drum 2, the 1-ply cord 15 is When the drum 2 is fed out by a length including the lap joint amount and crimped, the drum 2 is stopped, and the 1-ply cord 15 on the tray 41 is cut by the cutter knife 119 of the cutter knife-shaped material cutting means 93. Ru. At this time, the one-ply cord 15 is pressed and fixed onto the cutting table 113 by the vacuum pad 110 due to the forward and downward state of the movable frame 85. The cutting means 93 is in a state in which the left and right cutter knives 119 are overlapped back and forth at the center position, and the material pressing cylinder 1
46 is activated, the material pressing body 149 descends, and presses the center of the portion of the one-ply cord 15 that will be the cut end. Subsequently, the pair of cutter knives 119 are moved into the knife holder 1 by the operation of the dual force knife lifting cylinder 132.
20 and cuts into the material, and while in the lowered state, the left and right traversing cylinders 136, 137 operate, and the carriage 117 traverses in the direction away from the left and right, that is, toward the outer edge in the width direction of the material, and the double-edged center is cut into the material. The 1-ply cord 155 is torn and cut by the knife 119.

In addition, l ply cord 15 by cutter knife 119
After the start of cutting, the roller 130 of the canter knife holder 124 separates from the )8 trend bundle member 135, and the shaft part 12
Although it can freely swing back and forth around center point 5, it is maintained in a vertical position by upper and lower springs 127. Therefore,
When the cutter knife 119 approaches the core material embedded in the 1-ply cord 15 and the resistance increases, the spring 127
The balance of the cutter knife 119 is lost and the resistance in the front-rear direction moves toward the side with less resistance. Therefore, the material is cut smoothly without cutting the core material, which not only prevents wear and tear of the cutter knife 119 and improves durability, but also improves the durability of the cutter knife 119. Productivity can be improved by reducing replacement work.

After cutting the 1-ply cord 15 in this way,
The cylinders 132 and 146 are actuated to raise the cutter knife 119 and the material presser 149, and the left and right transverse cylinders 136 and 137 are actuated to return the carriages 107 to the center and move the double-force vine-knife holder 124. While the swinging is restrained, the Ishioka cutter knife 119 is fixedly positioned at J and waits until the start of the next cutting.

Then, when the cutting work of the l-ply cord 15 is completed,
The forming drum 2 rotates again, and the cut end of the l-ply cord 15 is brought into an overlap joint with the already crimped cut start end.

Subsequently, the tire building drum 2 rotates, and when the starting end of the adhesion of the next two blinds 16 reaches the approach position of the tray 42, the tire building drum 2 stops.

On the other hand, the tray 41 and the movable frame 85 are moved back, and the air motor 22 of the material support and feeding means 12 is started to wind up the 1-ply cord 15 by a predetermined amount so that no excess slack is generated. One application crimping cycle of 15 is completed.
