본 발명은 트럭이나 버스용 타이어를 제조하는데 사용되는 반제품의 하나인 리코트 및 리코트 제조장치에 관한 것으로, 리코트의 표면에 다수의 그루부라인과 프리킹홀을 형성한 공기배출수단이 가공된 리코트 및 그 제조장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recoat and recoat manufacturing apparatus, which is one of semi-finished products used to manufacture truck or bus tires. It relates to a recoat and a manufacturing apparatus thereof.

트럭이나 버스용 타이어를 구성하는 반제품 중 인너라이너(INNER LINER)와 바디플라이(BODYPLY)간의 접착력을 보강하기 위해서는 시트(SHEET)형태로 이루어진 리코트(RECOAT)라는 반제품을 사용하여 그 사이에 형성시킨다.In order to reinforce the adhesive force between the inner liner and body fly among the semi-finished products constituting the tires for trucks and buses, semi-finished products called RECOAT in the form of sheets are formed between them. .

상기 리코트를 부착하는 작업은 성형드럼위에 인너라이너, 리코트, 바디플라이 순으로 반제품을 부착하여 성형작업을 거쳐 1차 그린케이스(GREEN CASE)가 완성되어 진다.Attaching the recoat is to attach the semi-finished product in the order of the inner liner, the recoat, and the body fly on the forming drum to form a primary green case through the forming operation.

상기 리코트는 압출기를 통한 고무를 롤러에 통과시키는 과정에서 시트형태의 반제품으로 완성된다. The recoat is completed as a semi-finished product in the form of a sheet in the process of passing the rubber through the extruder to the roller.

종래의 리코드 제조장치는 압출기, 압연롤러(ROLLER), 시트 권취장치로 구성되어 있고, 압연된 리코트는 시트 표면상에 어떠한 형태의 자국을 남겨 놓지 않게 되어있다.The conventional record manufacturing apparatus is composed of an extruder, a rolling roller (ROLLER), a sheet winding device, the rolled record is not to leave any form of marks on the sheet surface.

즉, 압연된 리코트가 권취장치로 이송되어 그대로 권취된 후 성형기로 운반되어 그린타이어를 성형하는데 사용되어 진다.That is, the rolled recoat is transferred to the winding apparatus, wound up as it is, and then transported to the molding machine to be used to form the green tire.

따라서 성형기의 카카스드럼(CARCASS DRUM)상에 인너라이너(INNER LINER), 리코트(RECOAT), 바디플라이(BODYPLY)등의 순서로 성형작업을 할 경우 인너라이너(INNER LINER)와 리코트(RECOAT) 사이에 에어포켓(AIR POCKET)이 발생하게 되어 가 류 과정에서 잠재된 공기(AIR)가 제거되지 못해 가류후 완제품 불량을 유발하게 된다. Therefore, the inner liner and the recoat are used when molding in the order of inner liner, recoat, body fly, etc. on the carcass drum of the molding machine. AIR POCKET occurs between) and latent air (AIR) is not removed during the vulcanization process, causing finished product defects after vulcanization.

본 발명은 그린타이어의 성형 및 가류과정에서 리코트와 인너라이너 사이에 잠재된 에어포켓(AIR POCKET)을 제거하기 위하여 리코트 표면위에 공기 배출수단을 형성하여 공기가 빠져나갈 수 있도록하는 그루부라인과 공기배출용 구멍이 뚫린 리코트를 제공하고 상기 리코트를 제조하는 장치를 제공하고자 하는 것에 그 특징이 있다.
The present invention provides a grooving line for forming air discharge means on the surface of the recoat in order to remove the air pocket latent between the recoat and the inner liner during molding and vulcanization of the green tire.
