Abstract

A side wall of a pipe is clamped by a first die and a second die to thereby clamp the pipe. The first die and the second die are made to approach each other while an end of the pipe is pressed toward the first die by the third die along a longitudinal direction of the pipe, to thereby form a spool between the first die and the second die. In a state where the spool is clamped by the first die and the second die, the third die is separated from the pipe along the longitudinal direction of the pipe so as to separate the second die and the third die from each other. Clamping of the pipe is released such that the first die and the second die separate from the side wall of the pipe, to thereby unclamp the pipe.
