ABSTRACT:
The present invention relates to a dryer section of a machine for the production of fibrous web, such as a paper web. The dryer section comprises at least one dryer group having at least one drying cylinder and an endless porous support belt that guides the web around each cylinder. This is followed by a reversing roll being formed as a suction roll. With the web being supported by said porous support belt the web directly contacts said reversing roll. A distance of at least 150 mm is provided between the cylinder and the reversing roll. A sealing strip extends transversely over and close to the inner side of the endless porous belt in the region where web and belt are traveling off the cylinder. For deflecting the air boundary layer which arrives together with the belt, a sealing support beam also extends transversely over the inner side of the belt and supports the sealing strip. The beam, the sealing strip, the reversing roll and a section of the belt which is tangential to the cylinder and the reversing roll together define an area of negative pressure.
