    Abstract: The invention relates to a device for producing corrugated pipes made of thermoplastic synthetic material, wherein supplementary moulding jaws (10) are guided in a circuit in pairs along a common moulding segment (1) which is adjacent to the injection head, are driven apart from each other on the end of the moulding segment (1) and are guided back to the beginning thereof separately from each other. Said device comprises a moulding segment device which is used to displace the moulding jaws along the moulding segment (1), said moulding segment device comprising a machine table (19) provided with drive means (20) for the moulding jaws (10) on the moulding segment (1), and a return device for returning the moulding jaws (10) from the end of the moulding segment (1) to the beginning thereof. Said return device also comprises an outlet component (2) which is used to separate the moulding jaws (10) on the end of the moulding segment (1) and/or an inlet component (3) which is used to bring together the moulding jaws (10) at the beginning of the moulding segment (1). According to the invention, the outlet component (2) and/or the inlet component (3) comprise drive means which can be moved in a perpendicular manner in relation to the plane of the machine table. The invention also relates to a moulding jaw for producing pipes.
