Description

프라스틱 필름의 절단 및 타공(打孔)방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 내부연결된 분리가능한 프라스틱 필름봉지의 연속상대(Contineous strips)를 제조하는 방법에서 사용할 수 있는 수직행정(行程) 가열-밀봉 및 타공장치의 설명도이고.
제2도는 톱니로 된 홈이파인 금속 타공칼날의 톱날면의 확대 평면도이다.

Claims (3)

  1. 약 50록크웰(Rockwell)이상의 경도를 갖는 경성금속 물질로서 금속칼날의 한면만을 파복시킨 금속 칼날과 프라스틱 필름을 접촉하여 프라스틱필름을 절단하는 방법.
  2. 약 50록크웰이상의 경도를 갖는 경성금속물질로서 한면만을 피복시킨 타공(打孔)칼날을 사용하는 것을 개선점으로 하여, 이 타공칼날의 한 모서리를 따라 톱니를 갖는 타공칼날의 톱니로 프라스틱 필름을 관통시킴으로서 프라스틱 필름을 타공시키는 방법.
  3. 저압-저밀도 폴리에틴렌플름관을 제조한 후, 약 50록크웰이상의 경도를 갖는 경성금속물질로서 톱니의 한면만을 피복시킨 타공칼날을 사용하는 것을 개선점으로하는 한 모서리를 따라 다수의 톱니를 갖춘 금속제 타공칼날을 사용하여 주기적인 길이방향간격으로 필름관 폭방향으로 가열밀봉을 행하고 또 동일 간격으로 필름관을 타공시킴으로성 저압-저밀도 폴리에틸렌 필름으로 구성된 내부연결된 분리가능 포장봉지의 연속상태(Contineous strips)를 제조하는 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
