Controlled deflection roll

A controlled deflection roll comprising:

• a stationary roll support;
• a roll shell rotatable about said stationary roll support;
• support elements for supporting said roll shell at said roll support;
• said support elements being movable in relation to the roll support, bearing upon said roll support and acting with a support force at the roll shell;
• regulators provided for the support elements for influencing their support force;
• said roll shell having opposed ends;
• position feelers provided for the ends of said roll shell in order to determine the position of the roll shell in relation to the roll support and deviations of the roll shell from a predetermined reference position;
• and
• said position feelers influencing said regulators of the support elements as a function of the deviation of the position of the roll shell from said predetermined reference position in a manner such that the roll shell is retained by the support elements at the region of the reference position.
