Beschreibung
Zusammenfassung:	The present invention provides a pipe-making apparatus and a pipe-making method capable of making a spiral pipe variably adjusting a diameter or a perimeter of the pipe without an inner periphery limiter. The pipe-making apparatus 3 has a drive roller 11 disposed on a head portion of an apparatus frame 3f in a machine height direction HD, a pipe end guide 21 disposed on a basal portion of the apparatus frame 3f in the machine height direction HD and a fitting height adjuster. The drive roller 11 obliquely pushes an unformed following strip portion 92 following a preceding pipe portion 91 in the strip member 90 to a fitting position 9q on an extending end portion 91e of the preceding pipe portion 91. The pipe end guide 21 guides the apparatus frame 3f along the extending end portion 91e. The fitting height adjuster has a pipe end engagement portion 22 and a height adjusting mechanism that adjusts a position of the pipe end engagement portion 22 with respect to the drive roller 11 in the machine height direction HD.
