Abstract

PURPOSE: To easily obtain a flexible tube of superior corrosion resistance by forming a bellows having an extension part at the end into one piece with a ringlike member and a blade, then folding back the extension part of said bellows and externally covering the weld zone.
CONSTITUTION: With the end part of a bellows 55 left as an extension part 59, the top part 57 of the bellows 55 is aligned with the end 52 of a blade 51 and the inside circumferential edge 54 of a ring member 53 and these are made into one piece by welding the contact point 58. Thence, an axial pressure is applied to the extension part 59 of the bellows 55 from the right side to bend the extention part 59 until both parts contact closely with each other. As a result, the extention part 59 is folded back with the peak of the trough parts as its first fold back point 62 and the peak 70 of the crest part as the 2nd fold back point 63, thus the fold back part 61 is allowed to closely contact with the weld zone 58 and the outer side face 60 of the ringlike member 53, whereby the weld zone 58 is externally covered.
