In the process of manufacturing a tire, a green tire molded through rubber semi-finished products is placed in a vulcanizer and subjected to a vulcanization process in which the compounded rubber is chemically bonded by applying a set time, temperature, and pressure. Here, in the curing process, the green tire is put into a vulcanizer having a curing mold installed therein, and the curing bladder mounted inside the green tire is inflated to press the green tire in the direction of the curing mold, and the set pressure and temperature for a certain time is applied to mold the outer surface of the green tire according to the shape of the inner surface of the curing mold.

As one of the important factors in the tire curing process, centering exists. One factor that causes the centering issue is the centering problem of the curing bladder and the green tire. When the green tire is inserted into the curing machine and the curing bladder expands during the curing process, the center of the curing bladder and the green tire If the centers do not match, there is a problem that the uniformity of the finished tire product is reduced.

As another factor that causes the above centering problem, a loader and an unloader are used to insert and remove the green tire into the vulcanizer, and the loader moves the green tire into the vulcanizer input, and the vulcanized tire is removed through an unloader. The loader and the unloader are put into and removed from the vulcanizer in a state where the tire bead is fixed by the shoe configuration that is caught on the bead part of the green tire. do. If the centering of the loader is out of alignment, the flow of rubber in the lower bead of the green tire is biased in one direction, resulting in a problem of poor centering of the bead. If the centering of the unloader is out of alignment, the middle of the PCI rim PCI defects may occur when the bead is not loaded, and the tire cannot be removed because the tire is not caught in the shoe of the unloader after vulcanization. do.
