A twin-wire drying section of a paper machine includes upper and lower rows of drying cylinders, an upper drying wire guided by the upper drying cylinders and upper guide rolls situa- ted between the upper drying cylinders, and a lower drying wire guided by the lower drying cylinders and lower guide rolls situated between the lower drying cylinders. A web is pressed by the upper wire in direct drying contact with the surfaces of the upper drying cylinders and is pressed by the lower wire in direct drying contact with the surfaces of the lower drying cylin- ders and has a free draw of a certain length between a drying cylinder of one row and a drying cylinder of another row. In accordance with the invention, a vacuum zone is arranged on a run of a drying wire between a drying cylinder and the next guide roll which causes the web to be suctioned against the drying wire so that the length of the free run of the web is substantially shor- tened. The suction is created by directing air jets in directions opposite to the running directions of the drying wire run and the guide roll which eject air from spaces behind them thereby creating the vacuum zone.
