Abstract
A rotatably supported roll (1), which is adapted to form a nip with a second roll, so as to advance therebetween a web of material. The load in the nip between the rolls can be controlled by an adjustable camber. To this end, an interior hollow space (13) is provided in the roll (1), which is filled with an incompressible pressure medium, and put under a controlled pressure, so as to cause the roll jacket (10/12) to bulge radially outwardly. This bulging can be significantly supported and influenced by a predetermined progression of the wall thickness of the jacket (10/12) in the axial direction of the roll.
