PIPE MANUFACTURING DEVICE FOR SPIRAL PIPE
Provided is a pipe-forming apparatus with which a spiral pipe can be formed using a simple configuration. A driving part 10 of a pipe end release-type pipe-forming apparatus 3 having a non-inner periphery restriction structure presses a following strip portion 92 toward a pipe end portion 91e of a preceding spiral pipe portion 91 obliquely with respect to a machine-height direction HD. A pipe end guide 20 is constrained in a machine-width direction WD with respect to the pipe end portion 91e, and slidably engaged in a propelling longitudinal direction LD. The pipe end guide 20 includes a flat-shaped receiving portion 21a,22a along the propelling longitudinal direction LD. The receiving portion 21a,22a configures to receive the pipe end portion (91e) from the reverse side. A pressing force for the following strip portion 92 provides a fitting force between the following strip portion 92 and the pipe end portion 91e, and a propelling force for forward propulsion.
