In an apparatus and a method for calibrating and for straightening pipe pieces (5) is one with calibration jaws (3) provided Kalibriereinhe i t (1). to which on rockers pivotal and movable in the horizontal plane, the conveying rollers (30) are connected on both sides in the vertical plane. in the calibration unit upon insertion of the feed motion to the section-wise feeding a piece of pipe (5) (1) is blocked while the vertical movement of the rockers (38) until the calibration jaws (3) touching in their closing movement to be calibrated pipe section almost. The latest with the contact of the pipe section by the jaws (3) the blocking of the rocker motion is canceled, and the acceleration in the calibration phase of the closing movement of the jaws (3) is reduced. After completion of the calibration process before the calibration jaws (3) are opened again, the seesaw movement of the rollers (30) is blocked again. To influence the movement of the rocker are brakes (44) provided, which are tightened upon insertion of the feed movement of the conveyor rollers (30). They are with the aid of sensors (26) are coupled to the calibration jaws (3). detachably, in addition, the sensor (26) are the same with the driving of the calibration jaws for opening and closing in operative connection.
