The present invention relates to cord fabric for a pneumatic tire. From the center to the edge, end per inch (EPI) is increased more than once and then decreased and the EPI of the outermost part is designed to be lower than the EPI of the center and central edge so that the EPI of a rolled product becomes uniform. Therefore, dent defects in finished tires are reduced, and the uniformity performance is improved, thereby providing stability when driving at high speed.

    본 발명은 공기입 타이어용 타이어용 코드지에 관한 것으로 중앙부에서 변부방향으로 갈수록 EPI(End per Inch)가 한번 이상 증가했다가 감소하고, 최변부의 EPI가 중앙부 및 중앙변부의 EPI보다 낮게 설계되어 압연물의 EPI가 균일해져 완제품 타이어의 덴트(Dent) 불량을 최소화 시키며 유니포미티(Uniformity) 성능을 향상시켜 고속 주행시 안정감을 주는 효과가 있다.
