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.

Abstract: Calender for a fibrous material web and method of operating a calender for a fibrous material web. The calender includes a first roll stack and a second roll stack each arranged in a common plane on a stanchion, each roll stack having a top deflection adjustment roll having a sleeve, a bottom deflection adjustment roll having a sleeve, and three intermediate rolls disposed between the top deflection adjustment roll and the bottom deflection adjustment roll, the uppermost the intermediate roll being fixedly mounted to the stanchion. The calender further has a deflection adjustment device having a sleeve lift supporting each sleeve, at least one deflection adjustment device facing the first roll stack in a first operative position and facing the second roll stack in a second operative position. A nonrotatable bracket supporting each deflection adjustment device and fixedly mounted to the stanchion is also provided.

Abstract: A calender for manufacturing a material web. A frame is supported at the top and bottom. At least five rolls are mounted on the frame such that axes of the rolls lie in a substantially common plane extending substantially parallel to the frame. The common plane extends at an acute angle relative to a horizontal plane.
