Abstract
A calender for full and light calendering has rollers disposed one above the other. At least the middle rollers are mounted on bearing blocks, which are supported by levers. The levers are pivotably mounted on respective support blocks. The levers can pivot between an upper stop and a lower stop. A lifting device for the lowest roller moves the lowest roller through a separation stroke between an operating position and a separation position. The lifting device also move the lowest roller through an overstroke between the operating position, through a relief position in which the support blocks are spaced from their respective support elements, into an overstroke position, in which the support blocks of some of the uppermost rollers are lifted to an inactive position to permit the calender to be used for light calendering.
