Abstract:
To enable a pipe to smoothly produce even if there is a step on an inner peripheral surface of an outer peripheral regulation body such as an existing pipe.SOLUTION: A subsequent belt part 92, which is not processed into a pipe, of a belt-like member 90 is asquint extruded from an inner periphery side of a precedent pipe part 91 by a driving part 10 of a pipe-making apparatus 3 to fit an edge 94 of the subsequent belt part 92 to a corresponding edge 93 preceding by one turn of the precedent pipe part 91 by the extruding force. A pipe end outer peripheral guide 23 is fixed to an extended end part 91e of the precedent pipe part 91 from an outer peripheral side. A rolling element 23c is protruded to a base part side from the pipe end outer periphery guide 23. A guide member 33 is protruded in a driving front direction from the pipe end outer peripheral guide. A guide plane 33e slanting to a top part side toward a driving front direction is formed on the guide member 33 from more base part side than a center of the rolling element 23c.SELECTED DRAWING: Figure 1
