| description | Both diameter expansion and contraction control and fitting stabilization are achieved at the same time in a pipe end release-type pipe-forming apparatus having a non-inner periphery restriction structure. A driving part 10 provided in an apparatus frame 30 of a pipe-forming apparatus 3N presses an unformed following strip portion 92 of the strip member 90. A reverse side guide portion 83 is engaged with a pipe end portion 91e of a preceding spiral pipe portion 91 from a reverse side. A face side guide portion 82 is engaged with the pipe end portion 91e from a face side. The face side guide portion 82 is shifted to the propulsion rear side beyond the reverse side guide portion 83. The following strip portion 92 is extruded from the driving part 10 toward an inter-guide clearance 84 between the reverse side guide portion 83 and the face side guide portion 82. The driving part 10 is position-adjustably attached to the guide portions 83, 82 or the apparatus frame 30 via a position adjustment mechanism 31a. |
