A drying section of a paper making machine which drying section is designed to perform drying of a fibrous web (W) and which drying section comprises: one or more through air drying cylinders each of which has an outer circumference and which through air drying cylinder(s) is/are arranged to be rotatable; a fabric that is permeable to air and arranged to run in a loop and which wraps a part of the outer circumference of each through air drying cylinder , the fabric further being arranged to run in a predetermined direction of movement and the loop of the fabric being divided in a web-carrying part in which the fabric carries the fibrous web (W) and wraps the through air cylinder(s) and a conditioning part , one side of the fabric being arranged to contact the fibrous web (W) in the web-carrying part and thus constitute a web-contacting side of the fabric , the web-carrying part extending from a receiving point which is either a pick-up point where a suction device inside the loop of the fabric is arranged to pick up a still wet fibrous web (W) from a previous section or a point on the fabric where the fabric comes into contact with a fiber slurry which is used to form the fibrous web (W) if the fabric also serves as a forming fabric, and from the receiving point to a transfer point where the drying section is designed to transfer the fibrous web (W) from the fabric to a further machine component, the conditioning part of the fabric loop extending in the predetermined direction of movement of the fabric from the transfer point to the receiving point ; a hood that covers the part of the outer circumference of each through air drying cylinder about which the fabric is wrapped; a plurality of lead rolls supporting the fabric in its loop; a cleaning section comprising at least one shower arranged to act on the fabric in the conditioning part of the fabric loop to wash away residue from the fabric ; a dewatering section that is arranged to act on the fabric in the conditioning part of the fabric loop to dewater the fabric in an area that lies after the cleaning section in the predetermined direction of movement of the fabric , the dewatering section comprising one or several suction dewatering devices ; an applicator section that is arranged in the conditioning part of the fabric loop in an area that lies after the dewatering section in the predetermined direction of movement of the fabric , the applicator section comprising at least one applicator arranged to apply a release agent on the fabric for facilitating release of a fibrous web (W) from the fabric at a later stage after the fibrous web (W) has been dried on said one or more through air drying cylinders , characterised in that the dewatering section of the fabric loop comprises a substantially vertical run (VR) of the fabric which substantially vertical run (VR) does not deviate more than 30° from a perfectly vertical plane, in that at least one suction dewatering device is placed along the vertical run (VR) of the fabric and located on the web-contacting side of the fabric such that it can perform dewatering on the web-contacting side of the fabric , in that the dewatering section either comprises a further suction dewatering device placed along the vertical run (VR) of the fabric on the side of the fabric that is opposite the web-contacting side or that that the dewatering section has room on the side opposite the web-contacting side of the fabric for installing a further suction dewatering device of at least the same size as the at least one suction dewatering device that is located on the web-contacting side of the fabric , and in that the predetermined direction of movement of the fabric in the substantially vertical run (VR) of the fabric loop along which the at least one suction dewatering device is placed is an upward direction. <EOS>
