Abstract: A curl-forming apparatus (1) includes: a main body (20) configured to deform a profile strip (100); and a support body (3) configured to support the main body (20) in a holding unit (4) for the profile strip (100). The profile strip (100) is helically wound on an inside of the holding unit (4). The main body (20) is disposed in a hollow part of the holding unit (4) and is configured to draw and deform the profile strip (100) inside the holding unit (4). The support body (3) is rotatable relative to the holding unit (4), and is configured to rotate about an axis of the holding unit (4) in synchronization with the main body (20) that draws the profile strip (100).

Abstract: A winding machine (1) includes a main body (20), a first arm (40), and a second arm (50). The main body (20) moves toward a winding direction front side as a profile strip (100) is added, while rotating at a winding direction front end portion of a formed pipe member (4). The first and the second arms (40) and (50) are supported by the main body (20) respectively at positions away from each other in a circumference direction of the formed pipe member (4), and extend toward a winding direction rear side between an existing pipe (2) and the formed pipe member (4). The first arm (40) includes a first restricting portion (43) that comes into contact with a winding direction front side of a reinforcement member (120) provided to the profile strip (100) forming the formed pipe member (4) via the profile strip (100).
