Abstract
A paper or board machine having a machine dryer section with a drying group with single-wire draw. A drying wire (F) presses the web (W) on a drying cylinder () against heated cylinder surfaces, and the web (W) remains at the side of the outside curve of reversing cylinders () situated between drying cylinders (). For enhancing runnability of the web (W), a runnability component () is in a pocket space (T) confined by two adjacent drying cylinders () and a reversing cylinder () situated between them and by the drying wire (F). The web (W) passes from the drying cylinder () to the reversing cylinder () as a short transfer of 80-400 mm, where a negative pressure effect produced by the runnability component () is applied and confined by seals of the runnability component () against the surfaces of the drying cylinder () and reversing cylinder ().
