PURPOSE: To flexibly change a pass line and a floor by regulating the height and the incline angle of a forming roll corresponding to the height and the incline angle of a formed part of a material to be formed. ;CONSTITUTION: Forming rolls 51, 52 of a gradually changing servo unit 5 form a gradual changing cross-section of a material to be formed M by sliding to the width direction of the material to be formed M with a linearly driving mechanism 57 and rotating corresponding to the angle of the side end surface of the material to be formed M with a rotation driving mechanism 56. A height regulating mechanism 58 regulates heights of the forming rolls 51, 52 corresponding to the height change of the material to be formed M. An incline regulating mechanism 59 regulates the incline angle of the forming rolls 51, 52 corresponding to the change of the incline angle of the material to be formed M. In such a way, twists, warps and end-wave phenomenon in the longitudinal direction of the material to be formed M can be prevented.;COPYRIGHT: (C)1995,JPO
