Abstract
A calender having one stack of rollers has a working nip formed between a hard roller and a soft roller. A changeover nip is formed between adjacent soft rollers. The changeover nip is arranged approximately in the center of the roller stack. The cumulative weight of the rollers is such that the sum of the loads per unit of length of the working nips disposed above the changeover nip is at least 80 percent of the sum of the loads per unit of length of the working nips disposed below the changeover nip.
