摘要
PURPOSE:To give surplus length easily to a filament body in a pipe body, by feeding a filament body into the pipe body at a speed exceeding a moving speed of a metallic tape, when the conduit body is obtained by moving the tape, forming the pipe, and welding it. CONSTITUTION:From a tape supply 4, a metallic tape 1' is fed out, and a pipe is formed by a roll forming type forming device 5. Also, to the device 5, a filament body 2 is supplied from a filament body supply 7, and is fed into a tape 1'' which has been formed to a pipe. In this case, the filament body 2 is fed in forcibly at a higher speed than a feed speed of the tape 1' by a pinch roll 8, is made to execute a snake motion in the tape 1'', and surplus length is given. Subsequently, a joint part of the tape 1'' is welded by a device 11, and a metallic pipe body 1 is formed successively. When a metallic pipe 3 having a filament body with surplus length, which has been obtained is wound around a rotating body 12, filament body push-in force of a roll 8 is not exerted further than the rotating body 12, and the surplus length can be given effectively.
