PIPE MAKING MACHINE AND PIPE MAKING METHOD

摘要

A winding machine (1) according to one embodiment includes a frame (2) that is installed inside an existing pipe (200), a joining mechanism (4) for joining a plastic strip (100), and a wheel (6) for supporting the joining mechanism (4) on an inner surface of the existing pipe (200). The joining mechanism (4) includes an inner roller (42) and an outer roller (43) that sandwich the plastic strip (100) from inside and outside. The wheel (6) includes a rotational shaft at a position different from positions of rotational shafts of the inner roller (42) and the outer roller (43). The outer roller (43) of the joining mechanism (4) is maintained in a state of being separated from the inner surface of the existing pipe (200).
