Abstract

본 발명은 유니포미티가 향상되는 공기입 타이어의 제조방법에 관한 것으로, 폭이 다른 다수장의 벨트 플라이를 차례로 접합한 다음 그 위에 트레드 조립체를 일체로 부착, 성형하여 구성되는 공기입 타이어의 제조방법에 있어서, 양단 경사각(α)이 20°내지 70°의 범위를 갖도록 재단공정에서 일정길이로 재단한 다수장의 벨트플라이(2)를 통상 방식대로 성형공정에서 카카이 플라이 위에 차례로 접합한 다음, 상기 벨트플라이(2)의 재단 된 경사각(α) 및 길이와 일치되게 하면서 벨트 삽입홈(3)을 형성한 트레드 조립체(1)의 상기 삽입홈(3)에 상기벨트 플라이(2)를 삽착하되, 상기 트레드 조립체(1)의 벨트삽입홈(3)과 상기 벨트플라이(2)의 경사각α) 및 길이를, 상기 벨트플라이(2)의 일부층 또는 전부층이 선택적으로 삽착될 수있도록 구성하여 통상방법에 따라 타이어로 제조하는 제조방법이며, 이로 인해 트레드와 벨트 플라이의 편심을 방지하여 중량의 편중을 방지하고 벨트 플라이 끝위에서 트레드와의 접착력을 향상함과 동시에 에어입 현상을 방지하여 내구성능 및 유니포미티를 크게 향상하게 된 특징이 있다.The present invention relates to a method for manufacturing a pneumatic tire that is improved in uniformity, a method of manufacturing a pneumatic tire consisting of joining a plurality of belt plies of different widths in sequence and then attaching and molding the tread assembly integrally thereon. In which the belt plies (2) cut to a certain length in the cutting process in such a manner that the inclination angle (alpha) of both ends is in the range of 20 ° to 70 ° are sequentially joined on the kakai ply in the forming process in the usual manner, and then the belt Insert the belt ply (2) into the insertion groove (3) of the tread assembly (1) forming the belt insertion groove (3) while matching the cut inclined angle (α) and length of the ply (2), Conventional method by configuring the belt insertion groove 3 of the tread assembly 1 and the inclination angle α and the length of the belt ply 2 so that some or all layers of the belt ply 2 can be selectively inserted. Ta It is a manufacturing method of la tires, which prevents eccentricity of tread and belt ply, prevents weight bias, improves adhesion with tread on the belt ply, and prevents air intake, thereby improving durability and uniformity. There is a feature that greatly improves the tee.
