ABSTRACT:
A hollow roll featuring a layer of permanent magnets along axial sections of the roll is provided. Pole carriers having permanent magnets are arranged opposite the layer of permanent magnets on the roll. The pole carriers are supported on a core carrier, preferably by means of hydraulic or pneumatic thrust elements, or servomotors. The polarity is arranged such that like poles of the magnets oppose one another. The pole carriers are arranged in an axial row, and are movable in guideways while supported by servoelements. The servoelements are preferably activated hydraulically or pneumatically.
