<4. Features>
(1) Since the reinforcing member 2 is linearly extended and conveyed to the fitting portion 6 and fitted between the ribs 12 of the strip-shaped member 1, the orientation of the reinforcing member 2 does not change during the transfer. Therefore, the reinforcing member 2 which is heavy and has high rigidity can be stably conveyed. For example, if the reinforcing member 2 is transported along a curved path, problems such as the reinforcing member 2 deviating from the path and the transport speed may vary, but the above-mentioned configuration causes such a problem. Can be prevented.

(2) Since the reinforcing member 2 is made of a metal material and the rigidity of the reinforcing member 2 and the strip-shaped member 1 are different, it is not easy to smoothly fit the reinforcing member 2 into the strip-shaped member 1. On the other hand, in the present embodiment, before the reinforcing member 2 is fitted into the band-shaped member 1, the reinforcing member 2 is provided with a winding habit of bending in an arc shape. As a result, the reinforcing member 2 can be smoothly fitted into the band-shaped member 1.

(3) In the fitting portion 6, since the rollers 62 to 65 are movable in the radial direction, for example, the winding of the pipeline rehabilitation member 100 in the take-up roll 71 progresses, and the diameter of the take-up roll 71 becomes large. When this happens, the rollers 62 to 65 of the fitting portion 6 are moved outward in the radial direction to prevent interference with the take-up roll. Various controls are possible for such movement of the rollers 62 to 65. For example, the diameter of the take-up roll 71 can be measured, and the rollers 62 to 65 can be automatically moved accordingly. Alternatively, the rollers 62 to 65 can be manually moved.
