Abstract
In a controlled deflection roll having a roll shell rotatable about a stationary carrier and braced by one or more support elements against the stationary carrier, the roll shell comprises an inner roll shell part and an outer roll shell part which, during operation of the controlled deflection roll, form a press or force fit with respect to one another, for instance, due to excess pressure in the interior of the controlled deflection roll or due to elastic pre-biasing of the parts of the roll shell. Upon pressure relief or the existence of negative pressure within the controlled deflection roll a play or clearance is formed between the outer roll shell part and the inner roll shell part of the roll shell which enables dismantling and exchange of the outer roll shell part of the roll shell without the need to dismantle the controlled deflection roll or to remove such from the machine.
