The present invention relates to a tread extrudate member for manufacturing a tire. In the tire manufacturing method in which manufacturing is performed through each process in the order of a refining process, a semi-finished product process, a forming process, and a vulcanization process, the tread extrudate member in a semi-finished state manufactured through an extrusion process of extruding tire rubber in the semi-finished process includes an extrudate body formed of a certain length and width, and a folded portion partitioned by repeatedly making partial cuts at intervals along both sides of the extrudate body in the width direction, wherein a folded portion is formed by forming an isosceles trapezoidal body and a V-shaped groove therebetween at intervals on both sides of the semi-finished tread extrudate member, so that the surface finish of both edges is uniformly formed by the folds when attaching the tread extrudate member using a forming drum in the forming process.
본 발명은 타이어 제조용 트레드 압출물부재에 관한 것으로, 정련공정과, 반제품공정과, 성형공정과, 가류공정 순으로 각 공정을 거쳐 제조가 이루어지는 타이어 제조 방법에 있어서, 상기 반제품공정내의 타이어 고무를 압출하는 압출공정을 통해 제조된 반제품 상태의 트레드 압출물부재는, 일정 길이와 폭으로 형성되는 압출물 몸체와, 상기 압출물 몸체의 폭 방향 양측의 양변을 따라 간격을 두고 반복해서 부분 절개하여 구획되도록 형성되는 접힘부를 포함하여 이루어지는 것으로, 반제품 상태인 트레드 압출물부재의 양변에 간격을 두고 등변사다리꼴 체와 그 사이에 V형 사이홈을 형성하여 접힘부를 형성함으로써, 성형공정에서 트레드 압출물부재를 성형 드럼을 이용하여 부착할 때 접힘부에 의하여 양측 가장자리의 표면 마감이 균일하게 형성되도록 하는 효과가 있다.
