Abstract

Longitudinal axial positions in a roll longitudinal axis of ring pistons fitted into a profile-variable rolling roll are detected with a higher degree of accuracy. In response to outputs representative of the detected longitudinal axial positions of the ring pistons, the positions of the ring pistons can be controlled with a high degree of accuracy, whereby controllability of shape of the rolling roll is enhanced.
