Abstract

수평으로 조정 가능한 상하의 작업롤러(10,11)가 부착된 적어도 두개의 롤러프레임(6,7)(롤러프레임에 의해 각각의 작업롤러는 직접적으로나 지지롤러(9)의 중간롤러를 통해 받쳐져 있다.)을 소유하는 열밴드 스트리트(6)나 적어도 두개의 스티치가 압연되는 리버어스(가역) 프레임속에서(열밴드 스트리트와 가열프레임 속에서 롤러밴드는 상태조절장치의 영향을 받는다) 롤러밴드(3,4)를 압연하는 방법은 롤러밴드(3,4)의 프로필에 대한 목표 윤곽이 미리 주어지면 롤러밴드의 프로필의 정확성과 평면 조성에 대한 요구에 따를 것을 허용하며, 목표 윤곽의 도달을 위해 순차적으로 두개의 조정부분 그룹들이 롤러밴드에 영향을 미치는데, 그중 분기점 두께 상단에 놓여 있는 롤러밴드 두께의 첫번째 그룹의 조정부분들(12,13)이 투입되고 특히 밴드 중앙과 관련, 중앙범위에 있는 롤러밴드의 윤곽에 영향을 미치는 반면에 분기점 두께 하단에 놓여 있는 롤러밴드 두께의 두번째 그룹의 조정 부분들(12,13)은 밴드 테두리 범위에 투입된다.
제8도에 의거 상술함.
