Abstract

PURPOSE: To manufacture the flexible pipe with an optional diameter at low cost by using a simple facility by a method wherein a belt body is delivered spirally while being processed in a corrugated shape, and the body is joined integrally.
CONSTITUTION: The beltlike body 1 from a drum 2 of a jack 3 is held to two rolls 4, 5 turned being synchronized by means of gears 23, 24, and drawn at a spiral pitch θ. The beltlike body 1 is wound spirally around the roll 4, being molding in the corrugated shape by the uneven surfaces of the rolls 4, 5, the winding is repeated on a cylinder section 4' of the roll 4 through form keeping rollers 15, 16, the butt sections are welded 8 by means of a torch 6 of an automatic welder 7, and the integral flexible pipe is formed. The pipe obtained is forwarded by means of guide rollers 11, 12, and wound on a drum 15 on a turntable 13 (The table 13 is rotated lest a twist should be generated in the flexible pipe as a product).
