Abstract
A roll includes a roll jacket (1) which is rotatably journalled on a stationary carrier (2), with an at least approximately stationary active element (3) being arranged between the roll jacket (1) and the carrier (2), and with the space (4) between the carrier (2) and the roll jacket (1) being at least partially filled with a liquid. Such rolls are in particular used in the manufacture or treatment of material webs. In order to reduce the undesired turbulence losses passages are provided which extend through the active elements (3) approximately in the circumferential direction of the roll.
