Abstract

The invention relates to a suction or ventilation roll of a machine for producing and/or finishing a paper, cardboard, tissue or other fibrous material web ( 2 ). Said roll comprises a rotatable, perforated roll jacket ( 1 ) and at least one pressure zone ( 9 ), which only extends over part of the roll circumference and is formed by a fixed pressure compartment ( 6 ) located in the interior of the roll and open towards the roll jacket ( 1 ). The pressure compartment ( 6 ) is connected to a negative- or excess-pressure source and is sealed in relation to the roll jacket ( 1 ) by means of at least one sealing element ( 7 ). One aim of the invention is to reduce the noise emissions. To achieve this, a substantially air-tight cover ( 5 ), which runs in the direction of the circumference and is located outside the pressure compartment ( 6 ), adjoins a sealing element ( 7 ), said cover making contact with the roll jacket ( 1 ), or being placed at a distance of less than 100 mm to the latter.
