Abstract
PURPOSE: To block the hollow part in the wall of a pipe at the end thereof by pressing a pressing member from the outer peripheral surface of the synthetic resin pipe which has been heated and softened, and cutting off the hollow part in the wall of said pipe while crushing the same.
CONSTITUTION: A cutting device 4 comprises a core mold 5, a pressing member supporting device 6 arranged at the outer periphery of the core mold 5 so that a gap allowing the synthetic resin pipe 1 to pass remains, and a pressing member 7 mounted on the device 6 movably in the direction of intersecting rectangularly the pipe shaft. The synthetic resin pipe 1 heated and softened at a temperature higher than the plasticization starting temperature is held in the core mold 5, and a pressing member 7 is pressed against the pipe from the outer peripheral side so that it intersects rectangularly the pipe shaft to crush a lot of continuous cavities 3 formed along the pipe shaft in the wall of the pipe 1, the cavities being cut off as they are blocked. Simultaneously with the cutting off, the opening of the end part of the pipe 1 is blocked.
