Abstract

본 발명은 내구력이 향상되는 공기입 타이어의 제조방법에 관한 것으로, 후리퍼(3)로 둘러싼 비드(1)와 에이펙스(2)의 둘레로 제1, 제2바디플라이를 턴업시킨 후 통상 방법에 따라 타이어를 제조하는 공기입 타이어의 제조방법에 있어서, 제1, 제2바디플라이(4) (5)의 턴업작업시 상기 제2바디플라이(5)의 끝(10)은 에이펙스(2) 통상위치까지 턴업하고, 상기 제1바디플라이(4)의 끝(9)은 벨트층(8) 하부까지 턴업하여 타이어로 제조하거나 또는 상기 제1바디플라이(4)의 턴업된 끝(9)에 가황고무 스트립(7)을 더 보충하여 통상방법에 따라 타이어로 제조함으로써, 바디플라이 턴업 부위에서 발생되던 쎄파레이션 사고를 방지하여 타이어 내구력을 향상케된 특징이 있다.The present invention relates to a method of manufacturing an air-inlet tire in which the durability is improved, wherein the first and second body plies are turned around the bead 1 surrounded by the rear ripper 3 and the apex 2, (10) of the second body ply (5) during the turn-up operation of the first and second body plies (4) and (5) And the end 9 of the first body ply 4 is turned up to the lower portion of the belt layer 8 to be made of a tire or vulcanized at the turned-up end 9 of the first body ply 4 By further supplementing the rubber strip 7 and fabricating it with a tire according to a conventional method, it is possible to prevent the occurrence of a defective part caused at the body fly turn-up part, thereby improving tire durability.
