원통형 합성수지필름의 냉각처리방법Cooling Treatment Method of Cylindrical Synthetic Resin Film

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 압출다이스로 압출되는 필름을 연신냉각시키는 장치의 종단면도.1 is a longitudinal sectional view of an apparatus for stretching and cooling a film extruded into an extrusion die.

제2도는 이축연신필름을 제조하기 위한 가열연신 냉각처리장치의 종단면도.2 is a longitudinal sectional view of a heat-stretching and cooling apparatus for producing a biaxially oriented film.

도면의 주요부분에 대한 부호의 설명Explanation of symbols for main parts of the drawings

Claims (1)

원통형 필름(1)의 주위에 쿨링링(2)을 장치하고 쿨링링(2)에 송풍기(3)를 설치하여 필름을 냉각처리 함에 있어서, 쿨링링(2)의 대략 중간부에 격벽(2')을 형성시키고, 송풍기(3)로 외부로부터 찬공기를 필름에 송출시키지 아니하고 원통형 필름(1) 근처의 공기를 외부로 흡출시켜 필름을 냉각시킴을 특징으로 하는 원통형 합성수지필름의 냉각처리방법.In the cooling of the film by installing the cooling ring 2 around the cylindrical film 1 and by installing the blower 3 in the cooling ring 2, the partition wall 2 'is formed at approximately the middle of the cooling ring 2. And cooling air by blowing air near the cylindrical film (1) to the outside without forming cold air from the outside through the blower (3) to the film. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
