    • 본 발명은 Rotary Screen Roller를 제작하는 과정에서 먼저 Master Roller를 만들 수 있어야만 Rotary Screen Roller를 생산할 수 있기 때문에 철 롤러(도면 1)를 머저 철 소재를 사용해서 원통 롤러(도면 1)를 정밀 연마하게 되고, 다시 이 원통 ㄹ롤러(도면 1)는 화공약품에 쉽게 전해되는 동(銅)을 전기분해에 의한 동전주(銅電鑄)로 철 롤러(도면 1)에 0.1mm 두께를 석출시키고, 다시 니켈을 원하는 두께 만큼 석출시키므로써 3중 구조의 원통 롤러(도면 3)가 만들어 지게 된다.
      이상의 3중 구조를 화공약품에 부식 내지 전해시키는 공정을 가지게 되고, 이때 철재 롤러(도면 1)의 원통 내부는 수지(樹脂)로 된 막(膜)을 가지게 해야 하며, 이 상태에서 동박막(銅薄膜)을 태워 제거하면 철롤러(도면 1)와 니켈 원통 롤러(도면 4)가 깨끗이 분리되게 된다.
      한편 전해 시에는 니켈 표면도 수지(樹脂)로 된 막(膜)을 형성시켜야 보호가 된다. 또한 화공약품으로 전해 시에는 동(銅)과 니켈이 화공약품에 전해된 차이를 응용하여, 동이 니켈보다 훨씬 빠르게 전해되는 차이를 응용한 기법이며, 아울러 니켈 박막 원통 롤러(도면 4)는 사진기술을 이용하여 Master Roller를 만들게 된다.
      한편으로는 철 롤러에 수지(도면 5)를 동(Cu) 대신에 도포한 후 수지(도면 5) 표면에 질산은(AgNO
      3 )을 석출한 후 니켈 전주(도면 3)를 형성시켜 3중 구조으 원통 롤러를 만듬과 동시에 분리시키는 방법으로는 수지막(樹脂膜)을 약품(인산)에 용해시키므로서 니켈 전주 롤러(도면 4)를 만드는 방법이다.
