Abstract (en)

A method of processing a web (2) by bringing said web into contact with at least one porous cylinder (1, 4, 6) having a mesh value of at least 100, a process fluid under pressure being passed through said porous cylinder with such a speed that the pressure drop of said fluid in the porous cylinder is fives times greater than the pressure drop across the web. An installation for processing a web thereby applying this method, comprises means for the relative movement of a web (2) along the outer surface of at least one porous cylinder (1, 4, 6) and means for feeding a pressurized process fluid through said cylinder and said web in the contacting zone between these two.
