Abstract
A deflection-controllable roll for a calender has an inner support element and an outer support element. Each of the two support elements has a pressure portion and a piston. The pressure portions have support areas with inner and outer pockets. The pistons have pressure areas which delimit an inner pressure chamber and an outer pressure chamber, both of which are connected on one side with the associated pocket by a feed line equipped with a throttle, and on the other side, by a feed line in the carrier. In this way, the deflection-controllable roll is capable of operating in a wide range of line loads, using the available pressures.
