SPIRAL SEAM PIPE MANUFACTURING MACHINE FOR MANUFACTURING WELDED SPIRAL SEAM PIPE FROM METAL BELT MATERIAL

摘要

PURPOSE: To enable separating and cutting a pipe, having a slight deviation from an annular cut surface of a pipe strand. CONSTITUTION: In order to control the speed in the pipe manufacturing direction of a separating unit, a measuring device 6 for measuring the strip material speed, a measuring device 62 for measuring the strip feeding angle between a strip leg 9 and the pipe axis 20, and a measuring camera for measuring the axial deviation of pipe separating and cutting at pipe center angle formed between it and the separating unit are provided.
