摘要： A spiral pipe 9 is formed by joining edges 93, 94 of adjacent turns of a strip member 90 while helically winding the strip member 90 using a pipe-making apparatus 3. A propulsive reaction force for moving in a winding direction of the strip member 90 is imparted to a following strip portion 92 or a preceding spiral pipe portion 91 of the strip member 90 by a propulsive reaction force imparting portion 10 of the pipe-making apparatus 3. The following strip portion 92 follows a preceding spiral pipe portion 91 that has already been made into a pipe. A resisting force in a direction opposite to the propulsive reaction force is imparted to the strip member 90 along the winding direction by a friction between a resisting force imparting portion 30 and the strip member 90 generated while the strip member 90 is moved forward. In this arrangement, a diameter limiting frame can be omitted, and thereby, the pipe-making apparatus 3 can be downsized.
