摘要： A method for drying of paper, in which method the paper web (W) to be dried is passed from the press section into a forward dryer section (D1), in which the web (W) is dried from the side of its bottom face in dryer groups (R1...RN) that apply a normal single-wire draw. The forward dryer section (D1) comprises exclusively single-wire groups (R1...RN) with normal single-wire draw. From the forward dryer section (D1) the paper web (W) is passed into a finishing section (D2). Here the paper web (W) is coated/surface-sized by means of a coating/surface-sizing equipment (20), dried in an after-dryer (30), in which the paper web (W) is dried in at least one dryer group (R21) that applies a normal single-wire draw. After this the paper web (W) is calendered and passed to a reeling station (50). In the method, the curling of the paper web (W) is controlled by means of elements (19; 31; 32; 33; 34; 35; 36; R32, R33; Dsyl, Dtela) and/or by means of assemblies and combinations formed out of said elements in the area of the forward dryer section (D1) and/or of the finishing section (D2). Further, a dry end of a paper machine is described, which comprises a forward dryer section (D1) and a finishing section (D2). The finishing section (D2) comprises a coating/surface-sizing equipment (20), and after-dryer (30), a calender (40), and a reeling station (50). The dry end comprises elements (19; 31; 32; 33; 34; 35; 36; R32, R33; Dsyl, Dtela) and/or assemblies and combinations formed out of said elements in view of controlling the curling of the paper web (W) in the area of the forward dryer section (D1) and/or of the finishing section (D2).

摘要： The invention concerns a method in the dryer section of a paper or board machine for control of the curl of paper, in which method steam treatment and/or moistening of the paper web (W) is/are employed. In the method, the operations carried out in view of controlling the curl of the paper web (W) are carried out in a number of stages and/or when the web (W) temperature is lower than 85 DEG C, preferably lower than 75 DEG C, and/or when the dry solids content of the web (W) is in the range of K1...K2, wherein K1 = ultimate dry solids content - 7 % and K2 = ultimate dry solids content + 3 %. Further, the invention concerns a paper or board machine, which comprises at least a headbox, a former, a press, and a dryer section, in which steam boxes or moistening devices are employed for control of the curl. There are at least two of said curl regulation devices in view of achieving a regulation of the curl in a number of stages, and/or said curl regulation devices have been fitted to operate in an area in which the web temperature is lower than 85 DEG C, preferably lower than 75 DEG C, and/or the dry solids content of the web is in a range of K1...K2, wherein K1 = ultimate dry solids content - 7 % and K2 = ultimate dry solids content + 3 %.
