ABSTRACT OF THE DISCLOSURE The method for manufacturing a pipe bend from a straight pipe piece by means of actuating members acting on the outside of said pipe piece and making an open shaping station, the diameter of said actuating members being expand- able and compressible under the action of force, said method comprises the steps of: stepwise moving said pipe piece to and through said shaping station; grasping and pulling said pipe piece during its move to said shaping station by means a reciprocating member during the progressive motion of said reciprocating member; introducing the leading end of said pipe piece into said shaping station, supporting said pipe piece on its inside: upsetting and calibrating said pipe piece by compressing said actuating members of said shaping station while maintaining said supporting of said pipe piece on its inside: loosening said reciprocating member from said pipe piece; retaining said pipe piece in said shaping station during the retrograde motion of said reciprocating member; and repeating these steps until said pipe piece has complete- ly passed said shaping station. The method allows a very precise advance, which can be automated. As a result, the calibration quality is consider- ably improved .
