Abstract

직물이나 편물, 비닐, 가죽 등과 같은 커버재료를 3차원으로 형상짓는 방법을 커버재료(18)및 가스발생반응의 시점에서 액체로부터 접성의 상태(16')로 변화하는 폴리우레탄 따위의 발포가능 액체 반응 혼합물의 층을 마련하고, 그 합성된 커버재료와 거품 층을 희망 최종 3차원의 형상에 상을 하는 면 형상을 가진 압형(21,22)안에서, 압축이 거품 층이 사실상 부품을 완료한 때, 그러나 그의 경화가 사실상 일어나기 전에 행해지게 압축하며, 커버재료에 점착된 거품 층을 경화 반응에 진행하게 함에 의하여 실행한다. 3차원의 커버재료 성형이 외부의 열이나 고압력 없이 이 방법에 의해 실행되므로 커버재료는 그의 본래의 모양과 고품질을 유지할수 있다. 반쪽 압형들(21,22)사이의 간격을 국부적으로 변화시킴에 의하여, 커버재료에 점착한 거품 증은 상이한 국부 두께와 경도를 가진 부분들이 마련될 수 있다.
