Claims (4)

  1. 플라스틱재료를 용해상태로 밀어내는 압출기의 고정용기(1)의 선단에 부설된 재료저장실과 그 재료저장실에 자유롭게 회전할수 있도록 지지되고, 또한 축대칭형의 개구부(5)와 그 개구부(5)에서 반지름방향으로 늘어나는 경사홈(8)으로 이루어진 회전금형과 그 회전금형을 회전구동하는 회전구동수단을 가지고 있는것을 특징으로 하는 플라스틱제 스크루피이더의 제조장치
  2. 제 1항에 있어서,상기한 개구부(5)에서 밀려나온 중축부분(10)의 바깥둘레에 상기한 경사홈(8)에서 밀려나온 나선부분(11)을 연속적으로 일체성형되는것을 특징으로 하는 플라스틱제 스크루피이더의 제조방법.
  3. 플라스틱재료를 용해상태로 밀어내는 압출기와 그 압출기의 토출구를 가로막도록 설치되어 중심부에 소정의 형상치수의 개구부(5)를 가지고 있고 그 개구부(5)에서 축방향으로 소정의 각도로 경사진 경사홈(8)이 형성되어 있고, 또한 압출기의 토출구에 대하여 자유롭게 회전할수 있도록 지지된 금형과 상기한 금형을 소정의 방향으로 회전구동하는 동력기구를 가지고 있는 장치를 사용하고, 상기한 금형의 개구부(5)에 의해 성형되는 축부분(10)과 상기한 절입에 의해 성형되는 나선부분(11)이 일체 또는 동시에 압출성형되는것을 특징으로하는 플라스틱제 스크루우피이더의 제조방법
  4. 플라스틱재료를 용해상태로 밀어내는 압출기와 그 압출기의 선단에 설치된 재료저장실(24)과 그 재료저장실(24)을 관통하는 심재(27)를 축방향으로 반송하는 반송수단과 상기한 재료저장실(24)의 2개의 관통구멍(25),(26)중에서 심재의출구쪽에 설치되어 축방향으로 소정의 경사각을 가진 경사홈(31) 이 있는 금형(28)과 그 금형(28) 및 상기한 심재(27)를 상대적으로 회전시키는 회전수단등을 가지고 있는 압출 성형자치를 사용하고, 상기한 반송수단과 상기한 회전수단을 작동시키면서 플라스틱재료를 상기한 금형(28)에서 압출하므로 상기한 심재(27)의 바깥둘레에 플라스틱을 나선 형상(33)으로 성형하는것을 특징으로 하는 플라스틱제 스크루우피이더의 제조방법
