PURPOSE:To subject a pipe stock to a bending in the prescribed shape without waving it and realize the productivity improvement and cost reduection by alternately bending the piled pipe stock fixed by placing on a horizontal base cleat part with a lift type roll part by the turning of a supporting base and pressing jig. CONSTITUTION:A pipe stock P is located by a stopper 5 to the cleat member 4 of the above of a horizontal supporting base 2 and fixed with the pressing of a chuck 7. The piled pipe stock P is subjected to a bending by the turning of the insertion pressing jig 13 at the die roll 101 part ascended by a cylinder 11 by rotating the supporting base 2. The bending is thereafter performed in the similar operation alternately by the die roll 102, 103... part. The piled pipe stock P is subjected to a bending in the prescribed shape without being waved. The meandering pipe is therefore worked with good productivity and the cost is reduced.
