PROBLEM TO BE SOLVED: To provide an automatic traveling piping machine in which a side edge part at the side of a band body newly supplied is engaged onto an end part of former pipe even in a case where there is narrow gap between the former pipe and the existing pipe and sufficient reaction force cannot be obtained from the band body.SOLUTION: There is provided an automatic traveling piping machine forming regenerated pipe in the existing pipe while adding profile 10 by engaging side edge part at rear side of newly supplied profile 10A with front end part of a former pipe 4. A first plate 40 is provided, which is supported on a frame, arranged in a closed manner to peripheral surface on the front end part of the former pipe 4 and in an opposing manner to the peripheral surface, and being thinner than a gap between the existing tube and the former pipe 4. A first restricting part 41 is arranged on the first plate 40, which suppresses avoiding of the front end part of the former pipe 4 outward in radial direction.SELECTED DRAWING: Figure 14 |
