    (54) Drying section in a paper making machine


    (57) The invention relates to a drying section in a paper making machine, comprising at least two drying cylin­ders (1) for running therearound an endless drying wire (3). Between successively mounted drying cylinders (1) is fitted a roll (2) around which said drying wire (3) is adapted to travel from a preceding drying cyl­inder to the next in the running direction of a web. Aligned with roll (2) is a guide surface (OP) or the like fitted with at least one nozzle element (7). This produces an air current in the direction of guide surface (OP) and thus the passage of a web (5) between the drying cylinders and based on coanda-effect and effected close to guide surface (OP) but spaced from drying wire (3).
