Abstract

PURPOSE: To obtain an evacuating apparatus of high accuracy with a simple installation by pressing the outside circumferential surface of a pipe inserted with an evacuating apparatus body of which the outside circumferential surface is formed into a screw shape by using segmental dies.
CONSTITUTION: An evacuating apparatus body 1 of which the outside circumferential surface is formed with spiral and sharp angled spiral crest shapes 1b is inserted into the inner side of a pipe 2 and is placed on a female die 9. Next, a male die body 10a and segmental dies 10b, 10c which are segmental dies are lowered to compress the pipe 2. In this way, the pipe 2 is contracted and the crest parts 1b of the body 1 gnaws into an inside wall 2a, thereby forming spiral fine spaces 1c.
