A compact roll arrangement has a device and method for regulating the roll nip so that intermittently coated films may be calendared precisely. A bearing block is arranged in a bearing jewel, and first lever arms of the clamping latch of the upper roll and the lower roll are connected rigidly to one another. Bearing jewels which lie opposite to one another, of the upper roll and the lower roll are connected to one another via a second actuating element. A controller acts on first and second actuating elements, so that the first actuating elements are moved to adjust the roll nip according to a predetermined thrust and a predetermined linear load, and the second actuating elements are moved to maintain the bearing jewels in a relative rest position which is defined by specified densification of a material web passing the roll nip.
