Claims (1)

필름을 종방향과 횡방향으로 각각 연신하는 축차 2축 연신방법에 있어서, 텐터를 연신 레일부와 응력 완화 레일부, 그리고 쿨링 레일부로 나누어 개별적으로 구동시키고, 상기한 응력완화 레일부를 외측으로 회전시켜 필름을 해방한 상태에서 쿨링 레일부의 속도를 연신 레일부의 속도보다 느리게 함과 아울러 응력완화 레일부에 설치된 댄스 롤을 승강시켜 횡방향 연신이 이루어지는 동안에 종방향의 연신이 이루어지도록 함을 특징으로 하는 필름 연신방법.In the sequential biaxial stretching method in which the film is stretched in the longitudinal direction and the transverse direction, respectively, the tenter is divided into the stretching rail portion, the stress relaxation rail portion, and the cooling rail portion, and driven separately, and the above-mentioned stress relaxation rail portion is rotated outward. While the film is released, the cooling rail portion is made slower than the stretching rail portion, and the dance roll provided in the stress relief rail portion is lifted to allow longitudinal stretching while transverse stretching is performed. Film stretching method to do. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
