MANUFACTURING METHOD OF BLADDER FOR TIRE VULCANIZATION AND BLADDER FOR TIRE VULCANIZATION

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a bladder for tire vulcanization capable of effectively regulating dilatation of a part corresponding to a tire crown part, and the bladder for tire vulcanization.;SOLUTION: In a bladder for tire vulcanization 2 used when a green tire T is vulcanized, the bladder for tire vulcanization 2 is constituted by a cylindrical bladder substrate 3 and a cyclic reinforcement layer 4 which is laminated on an outer peripheral surface of a part corresponding to a tire crow part T1 of the bladder substrate 3 and the cyclic reinforcement layer 4 is formed on the outer peripheral surface of the part corresponding to the tire crow part T1 of the bladder substrate 3 in a state that the vulcanized bladder substrate 3 is dilated by an inner pressure.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2017,JPO&INPIT
