    • The invention concerns a method to adhere a web (W) to a drying wire (H) against the centrifugal forces and various blow phenomena, which attempt to detach the web (W) from said wire (H) in the drying groups provided with single-wire draw in a multi-cylinder dryer of paper machine. The drying groups comprise as upper cylinders drying cylinders (K) heated by means of steam or equivalent and the web (W) is pressed by the drying wire (H) against outer cylinder faces of said drying cylinders (K). The drying groups further comprise as lower cylinders leading cylinders (10) on which the web (W) runs outside the drying wire (H), said leading cylinders (10) being provided with holes (15) passing through a mantle (11) of the leading cylinders (10). The holes (15) open into an interior space (14) of negative pressure (Pi) in the leading cylinders (10) and into the outer face of said cylinders (10), said negative pressure (Pi) being transmitted to said outer face through said holes (15). The leading cylinders (10) comprise shafts (18) on which the respective leading cylinder (10) is journalled revolving, and at least one of said shafts (18) has a duct (18a) through which said negative pressure (Pi) is applied to the space (14) inside said cylinder (10). The shafts (18) communicate with a suction duct (19) from a source (20) of said negative pressure (Pi). A part of the holes (15) in each leading cylinder (10) opens into the open air in the upper part of the leading cylinder (10) so that flow of air is directed into the interior (14) space of said cylinder. Said negative pressure (Pi) in said interior space (14) is selected within the range of 1000 Pa to 3000 Pa.

    • Method and dryer section in contact-drying of a paper web (W). The paper web (W) is dried by means of heated smooth-faced drying cylinders (10, 20A,20B) by using a number of successive so-called normal groups (R₁...R N ) with single-wire draw, in which the drying cylinders (10) are placed in the upper row and the reversing suction cylinders (11) in the lower row. After the press section of the paper machine, the paper web (W) is dried initially in a number of successive groups (R₁...R N ) with single-wire draw by pressing the paper web (W) by means of the drying wire (15) of the cylinder group against the heated faces of the drying cylinders (10) and by, in each group (R₁...R N ) with single-wire draw, passing the paper web (W) on support of the same drying wire (15) from one drying cylinder (10) onto the other drying cylinder over reversing suction cylinders (11) or rolls. By means of the groups (R₁...R N ) with single-wire draw, the paper web (W) is dried to a dry solids content of k₁ = 70...92 %. After the drying steps which were carried out exclusively by means of normal groups (R₁...R N ) with single-wire draw, the paper web (W) is dried immediately further by means of one single group (R TW ) with twin-wire draw to its ultimate dry solids content.
