PURPOSE:To prevent thickness deviation of a pipe by positioning the tip of a displacement detecting lever parallel to the end face of die side of a container, and detecting the displacement of the tip as change of load acting on the lever, and changing the attitude of the container holder. CONSTITUTION:A die 7 and a container 12 are brought into close contact in a proper state, and amount of projection of contact terminal is set to make initial deflection of contact terminal of a displacement detecting lever 19 a specified value. Presetting is made so as to make output of each detector 26 zero under this state. When there are displacement in the direction of stem, and in the direction of counter-platen 10 side, amount of distortion at the detector 26 including the direction of displacement is inputted to an arithmetic device 27, and actual amount of displacement and inclination is calculated and inputted to a controller 28. The controller 28 determines a cylinder 24 to be operated, amount and direction of operation in accordance with the result of calculation, and operates the specified cylinder 24 through a servovalve 29 to change the attitude of a container holder 13. Thus, the center line of the container 12 is aligned to axis L. |
