Abstract

본 발명은 열가소성 수지가 다이를 통하여 용융, 압출되어 용융쉬트의 형태로 성형되는 단계 및 상기 단계에서 성형된 쉬트가 다이 하방에 설치되어 있는 냉각롤을 거쳐 고화 쉬트로 제조되는 단계를 포함하는 열가소성 수지 쉬트의 제조 방법에 있어서, 상기 다이와 스트리퍼롤 사이에 냉각롤 표면의 올리고머를 제거하기 위한 복사가열장치가 설치되어 있는 것을 특징으로 하는 방법이다.
본 발명에 의하면 올리고머의 부착으로 인한 냉각롤 청소를 위해 제막 작업을 휴지하지 않아도 되므로 가동률을 향상시킬 수 있으며, 제조된 쉬트의 표면에서 발생될 수 있는 결함을 줄일 수 있게 된다.
