Abstract:
The invention relates to a web-guiding device comprising at least one directing element ( 10 ) for guiding a web in a contactless manner in a machine that is used for producing and/or treating a moved web of material ( 1 ), especially a paper or cardboard web. Said directing element ( 10 ) is provided with a directing surface ( 12 ) that is made at least in part of air-permeable porous material ( 14 ) which can be impinged upon by compressed air so as to form an air cushion ( 18 ) between the directing surface ( 12 ) and the moved web of material ( 1 ) via the air ( 16 ) flowing through said porous material ( 14 ). The directing surface ( 12 ) is divided into at least one web transfer zone ( 2, 4 ) and a web-guiding zone ( 3 ) along the direction of movement ( 2 ) of the web of material. Said zones ( 2, 4; 3 ) are embodied so as to allow for a different air throughput.
