Claims (1)

  1. 압출성형기에 압출구에서 압출된 수지관이 맨드렐에 당도하기 전에 일차로 압출구 직전에서 수지관 내면을 향하여 압축공기를 분사하고, 이차적으로는 역시 수지관 내부에서 냉각수 또는 오일을 분사하여 수지관과 맨드렐 사이에 수막 또는 유막을 형성하며, 수막 또는 유막에 윤활작용에 의하여 수지관과 맨드렐 상호간에 마찰저항을 감초시키고, 맨드렐 내부에 냉각수 순환과 그 외주로부터 진공압으로 흡인하기 위한 진공 및 분사용 냉각수 그리고 분사용 압축공기 등을 수동게이지로서 미조정하여 성형하며, 니플을 계수에 연결조작으로 맨드렐과 선택적으로 회전할 수 있게 한 것을 특징으로 하는 나선형 수지관에 제조방법.
