Abstract
Abstract An adjustable deflection roll including a roll sleeve or jacket supported by a plurality of support devices positioned partially within a support beam. Pressure chambers may be located between the support devices and the support beam and each pressure chamber may be coupled to a supply line. As the length of the roll increases, and as the need for increasingly more precise pressure distributions also increases, more support devices may be utilized. The adjustable deflection roll may also include a drain channel to facilitate quick relief of the pressure chambers when necessary. To accomplish this, each pressure chamber may be coupled to the drain channel furnished with the supply line such that the drain channel may be closed with a drain valve.
