Abstract

본 발명은 내구력이 향상되는 공기입 타이어의 후리핑 방법에 관한 것으로, 비드(4)(4')와 에이펙스(3)의 둘레로 후리퍼를 감싸서 제조되는 공기입 타이어의 후리핑방법에 있어서, 후리퍼(15)로 상기 비드(4)(4')와 에이펙스(3)의 둘레를 감쌀 때 상기 에이펙스(3)의 상부 외측면이 일부 노출되게 감싸서 이루어지며, 이로인해 후리핑 작업시 에이펙스와 후리퍼간의 에어입을 방지하여 완제품 타이어의 비드부위 에어입 불량을 방지함과 동시에 이러한 비드부위의 잔존공기로 인해 노면주행시 일어나는 비드부위의 세파레이션 사고를 방지하여 공기입 타이어의 내구수명을 연장하게 되는 특징이 있다.The present invention relates to a method of backing a pneumatic tire with improved durability and, in a method of backing a pneumatic tire manufactured by wrapping a back ripper around a bead (4) 4 'and an apex (3) When the bead 4 or 4 'and the apex 3 are wrapped around the bead 4 with the back ripper 15, the upper outer surface of the apex 3 is partly exposed so as to be partially exposed. And prevents the air from entering the bead portion of the finished product tire while preventing the air from entering the bead portion of the finished tire. Also, the remaining air in the bead portion prevents the beveled portion of the bead portion caused by running on the road surface, Feature.
