Abstract

A method for forming green tires is provided to allow formation of green tires using a rigid core, and to avoid turn-up work of the end of carcass, while preventing bead clusters from escaping from the end of a carcass. A method for forming green tires comprises a step of disposing an inner liner(1) on a drum, a belt and tread rubber on a tread section, sidewall forming rubber on a sidewall, and bead clusters on a bead section. In the method, a first layer of bead wire clusters(2) is disposed on the bead portion outside the inner liner in such a manner that the first layer of bead wire clusters is divided. Also, the carcass(3) is disposed outside the first layer in such a manner that the carcass compresses such divided portion and the divided portion(21) between preliminarily installed wire clusters is filled with a part of the carcass. Then, a second layer of wire clusters(4) is disposed outside the carcass in such a manner that the dented portion of the carcass is filled with the second layer of wire clusters and the end of the carcass is coupled in zigzag pattern to the bead wire clusters. Further, a third layer of wire clusters is disposed at the outside of the second layer, and a steel chapper is disposed outside the bead portion.

본 발명은 그린 타이어 제조 방법에 관한 것이다.The present invention relates to a green tire manufacturing method.

타이어는 드럼(Drum)에 인너라이너고무판을 씌우고 그 위에 카카스층을 설치하며 양측에 비드부를 설치하고 비드부 양측의 카카스를 접어 올려(Turn up) 비드부를 고정시키고 비드부와 비드부 사이를 부풀려 타이어 형태의 중간 성형물을 제조하게 되는 바 이러한 중간 공정에서의 타이어를 그린 타이어라 한다. 본 발명은 이러한 그린타이어를 제조하는 방법에 관한 것이다.The tire is covered with an inner liner rubber plate on the drum, a carcass layer is installed on it, bead parts are installed on both sides, and the carcass on both sides of the bead part is folded up to fix the bead part, and there is a gap between the bead part and the bead part. Inflated to produce an intermediate molding in the form of a tire, the tire in this intermediate process is called a green tire. The present invention relates to a method for producing such a green tire.

그런데, 이와 같은 그린타이어를 제조함에 있어서 그 중간부를 부풀리게 되면, 그 부풀리게 되는 정도가 일정할 수 없어 타이어는 균일성을 상실할 염려가 크다. 한 편, 그린 타이어를 제조함에 있어서는 카카스 단부에 설치하는 비드부가 빠져 나가지 아니하도록 비드부를 붙잡기 위하여 카카스 단부를 턴엎시키게 되는 바, 이와 같은 턴엎 공정은 그린타이어를 원통형의 드럼위에서 작업하게 할 것을 강요하고 따라서 위와 같은 부풀림 공정을 필연으로 하였으며, 그리하여, 종래에는 리지드 코아(Rigid Core)를 이용하여서는 그린 타이어를 제조할 수가 없었다. However, when the middle portion is inflated in manufacturing such a green tire, the degree of inflation cannot be constant and the tire is highly likely to lose uniformity. On the other hand, in manufacturing a green tire, the carcass end is turned to catch the bead portion so that the bead portion installed at the carcass end does not come out. This turnover process is intended to cause the green tire to work on a cylindrical drum. The inflation process is inevitably necessary, and thus, a green tire cannot be manufactured by using a rigid core.

그런데, 본 발명자는, 어차피 비드부 단부는 스틸 채퍼에 의하여 보강되는 것이므로 비드뭉치가 카카스 단부로부터 빠져 나가는 것을 방지할 수만 있다면 카 카스 단부를 턴업시키지 아니할 수 있고, 그렇다면 리지드 코아(Rigid Core)를 이용한 그린타이어의 제조가 가능하다고 생각하였다. 그리하여 본 발명자는, 비드부에 비드뭉치를 형성시킴에 있어서, 제1층 비드와이어 뭉치를 설치하되 비드와이어 뭉치를 분할하여 설치한 후, 그 외측에 카카스를 설치하되 카카스의 일부가 먼저 설치된 와이어 뭉치의 분할부 사이를 채우게 하고, 카카스 외측에 다시 제2와이어뭉치를 설치하되 제2와이어 뭉치가 카카스의 몰입부를 채움으로서 카카스 단부와 비드와이어뭉치가 지그재그로 완강히 결합되게 하며, 나아가 분할 와이어뭉치에 카카스를 설치하고 카카스 몰입부를 채우는 와이어뭉치를 설치하며 다시 그 외측에 카카스를 설치하고 그 외측에 와이어뭉치를 설치하여 비드부를 구성시키어 비드뭉치가 카카스 단부에 지그재그로 얽히면서 완강히 결합되게 함으로서, 카카스 단부의 턴엎 작업을 필요로 하지 아니하게 하여 토러스 드럼을 사용한 그린 타이어의 제조를 가능하게 한 것인 바, 이와 같은 본 발명의 그린타이어 제조 방법을 첨부된 도면에 의하여 설명하면 다음과 같다.However, the inventors of the present invention can not turn up the carcass end as long as the bead end is reinforced by a steel chafer, so that the bead bunch can be prevented from escaping from the carcass end, and if so, the rigid core It was thought that manufacture of the used green tire was possible. Thus, in the present invention, in forming a bead bundle in the bead portion, the first layer bead wire bundle is installed, but after dividing and installing the bead wire bundle, the carcass is installed on the outside, but a part of the carcass is first installed. Fill the space between the divided portions of the wire bundle, and install the second wire bundle again outside the carcass, but the second wire bundle fills the immersion of the carcass so that the carcass end and the bead wire bundle are firmly coupled in a zigzag, and furthermore, Install the carcass on the divided wire bundle, install the wire bundle to fill the carcass immersion part, and then install the carcass on the outside of it and install the wire bundle on the outside to form the bead part, and the bead bundle is zigzag in the carcass end. By tightly coupling, the torus drum is used without the need to turn over the carcass end. When the bars, illustrated by the accompanying drawings, such a green tire production method of the present invention in the manufacture of a green tire to enable the following:
