ABSTRACT OF THE DISCLOSURE The surfaces of cylinders or fabrics moving in the press or drying section of a paper machine induce layers of air to move along with them. These layers of air produce positive and nega- tive pressures at the clefts defined by the fabric/web and by the cylinder surfaces. These positive and negative pressures are detrimental to the mutual support contact between the web and the fabric. A method is suggested by means of which the said de- trimental positive and negative pressures are reduced. The pressure levels at the clefts are adjusted by blowing air in directions opposite to the direction of travel of the web/fabric from blowing means close to the web/fabric, and possibly also in directions opposite to the direction of travel of the cylinder This results in air being ejected from the pressurized clefts or from zones facing the clefts at negative pressure on the opposite side of the web/fabric.
