Abstract
The present invention relates to a calendar for treating a material web. In an exemplary embodiment, first and second roll stacks have first and second deflection adjustment rolls on an end thereof, respectively. Each of the first and second deflection adjustment rolls has a sleeve lift, and a sleeve supported by a deflection adjustment device on a fixed bracket. The first and second deflection adjustment rolls are adjacent to each other to define an additional nip therebetween that can be at least partially closed by the sleeve lift. An effective direction of the deflection adjustment device of the first deflection adjustment roll alternatively points toward the first roll stack and the second deflection adjustment roll, and an effective direction of the deflection adjustment device of the second deflection adjustment roll alternatively points toward the second roll stack and the first deflection adjustment roll.
