Abstract
A high speed dryer section has single-wire draw drying groups (R , R ). A paper or board web (W) is supported by a wire (F) as it meanders over drying cylinders ( ) in an upper row and reversing cylinders/rolls ( ) in a lower row. A first cylinder drying group (R ) has at least five drying cylinders. In the first cylinder drying group (R ) a runnability component ( ) is placed in a pocket space defined by every two successive drying cylinders ( ) and the reversing roll ( ) between them and by the drying wire (F) for applying a high under-pressure of 1000-8000 Pa to an area ( Y) in which the web (W) separates from the drying cylinder ( ), and by which runnability component ( ) a lower under-pressure of 100-500 Pa is produced in at least part of the rest of the pocket space (T).
