摘要： A dryer section of a paper machine which is provided with at least one intermediate calendering nip and includes several successively arranged wire groups. The dryer section primarily or exclusively has groups with single-wire draw in which heated drying cylinders are arranged in an upper row and reversing suction cylinders or reversing suction rolls are arranged in a lower row below the upper row. The groups with single-wire draw also have a drying wire which runs along a meandering path over the drying cylinders and reversing suction cylinders or rolls so that the reversing suction cylinders remain inside the loop of the drying wire. A calender roll is arranged in opposed relationship to a drying cylinder in one or more of the single-wire draw groups in a sector which the first face of the web is exposed to thereby define a calendering nip therewith.

摘要： A method and device for enhancing the run of a web in a paper machine in which water is removed from the web by pressing the web in at least one press nip and after pressing, the web is dried in at least one dryer group applying impingement drying. The web is guided along a substantially linear path or by using a large curve radius in the dryer group applying impingement drying. In the drying stage, after the impingement drying, the web is dried in at least one dryer group having normal single-wire draw. The web is passed from the pressing stage to the drying stage as a closed draw and more particularly, from the pressing stage to the area with single-wire draw in the drying stage so that the web is constantly supported against at least one support face.

摘要： A dry end of a paper machine and a method for drying paper in which a paper web to be dried is passed from a press section of the paper machine into a forward dryer section including only single-wire groups with normal single-wire draw. The web is dried from the side of its bottom face in the dryer groups in the forward dryer section. From the forward dryer section, the web is passed into a finishing section in which the web is coated/surface-sized by a coating/surface-sizing device and then dried in an after-dryer by passing through at least one dryer group that applies a normal single-wire draw. Thereafter, the web is calendered and passed to a reeling station. Curling of the web is controlled by the operation or construction of components and/or by assemblies and combinations formed out of these components provided in connection with the forward dryer section and/or the finishing section.

摘要： A method and arrangement for evaporation drying of a paper web in which the web is dried in three successive stages I, II and III that are carried out in the direction of progress of the web as follows: in the first stage (I), the web is heated in a short section in the machine direction quickly to a temperature of 55.degree. C. to 85.degree. C. minimizing web breaks of the relatively moist and weak web, after the first stage (I), the main evaporation drying of the web is carried out so that the evaporation efficiency and the rate of increase in the dry solids content of the web are substantially higher than in the first stage or in the final stage (III), and the web temperature does not substantially rise while the drying proceeds, and in the final stage (III), the drying is continued with a decreasing evaporation efficiency and an average rate of increase in the dry solids content of the web in the machine direction which is lower than in the preceding stage (II) but higher than in a conventional cylinder drying with single-wire draw so that the paper quality is controlled at the same time.

摘要： The invention concerns a method and a device in the dryer section of a paper/board machine. In the dryer section a normal single-wire draw is applied at least partly, in which method the web (W) is passed through the dryer group on support of a drying wire (H). The drying wire (H) presses the web (W) on the drying cylinders (Kn, Kn+1 . . . ) against the heated cylinder faces, and on the reversing cylinders or rolls (Sn, Sn+1 . . . ) between the drying cylinders (10) the web (W) remains at the side of the outside curve. There is one integrated device, through which a support suction and/or blowing is produced in order to improve the runability of the web (W) and to keep the web (W) in contact with the face of the wire, and through which same device, additionally, impingement blowing is produced in order to dry the web (W) and/or to control its tendency of curling.
