Abstract
Between an uppermost roll and a lowermost roll there are arranged intermediate rolls mounted with their axles in levers. These levers extend across the width of the roll stand of the calender and are vertically pivotably suspended at a pivot at the roll stand. Nip relieving devices act upon these levers and are supported at a support defining a support location at the roll stand. Each pivot is arranged at an associated bearing element which is elevationally adjustable and which is located at the rear side of the roll stand remote from the rolls. If the position of the intermediate rolls change in vertical direction, the related bearing elements are correspondingly individually and vertically displaced, so that the levers are brought into an essentially horizontal position at which the axles of the intermediate rolls and the pivots of the related levers are located in each case in a related horizontal plane. An advantageous construction has the bearing element vertically displaced along a guide by rotating a threaded spindle, to which the bearing element is individually engagable by a coupling device.
