摘要： The invention concerns a method and a device in the drying of a paper web (W), wherein, after the press section (20) of the paper machine, the paper web (W) is dried in a number of successive groups (R 1 ...R N ;R S ) with single-wire draw, in which groups the contact-drying cylinders (10) are placed in the upper row and the reversing suction cylinders (11) or equivalent suction rolls in the lower row or in equivalent diagonal or vertical rows. The paper web (W) is pressed by means of the drying wire (15) against the heated faces of the contact-drying cylinders (10), and the paper web (W) is passed, in each group (R 1 ...R N ) with single-wire draw, on support of the same drying wire (15) from one contact-drying cylinder (10) onto the next contact-drying cylinder over the reversing suction cylinders (11) or equivalent suction rolls. When the paper web (W) is placed at the side of the outside curve on the drying wire (15), the web (W) is held on the wire by means of a difference in pressure against the effect of centrifugal forces. The paper web (W) is dried from the side of its lower face substantially across the entire length of the dryer section by means of said contact-drying cylinders (10). The paper web (W) is dried from the side of the upper face of the paper web (W) applying heat through the drying wire (15), thereby the drying of the paper web (W) from the side of its upper face is promoted.

摘要： The invention concerns a method in the drying of a paper web, in which method, after the press section of the paper machine, the paper web is dried in a number of successive groups with single-wire draw, in which groups the contact-drying cylinders are placed in the upper row and the reversing suction cylinders in the lower row or in equivalent diagonal or vertical rows. In the method the paper web is pressed by means of the drying wire against the heated faces of the contact-drying cylinders, and the paper web is passed, in each group with single-wire draw, on support of the same drying wire from one contact-drying cylinder onto the next contact-drying cylinder over the reversing suction cylinders. From the side of its lower face, across the entire length of the dryer section, the paper web is dried by means of contact-drying cylinders. The paper web is passed as a closed draw from one group with single-wire draw to the next group. The paper web is guided, while it is placed on the drying wire at the side of the outside curve, by means of said reversing suction cylinders with a curve radius D 2 /2, which is chosen as D 2 /2 ≈ 250...1000 mm, preferably D 2 /2 ≈ 500...800 mm, that the paper web is kept in constant contact with the drying wire, as it is placed at the side of the outside curve, against the effect of centrifugal forces by means of a difference in pressure, which difference in pressure is extended over the entire inner circumference of said reversing suction cylinders, and that onto the lower face of the paper web a moist medium is fed, preferably moist air and/or water mist, so as to equalize the moisture profile of the paper web in the z-direction.
摘要翻译：本发明涉及一种干燥纸幅的方法，在该方法中，在造纸机的压榨部之后，纸幅以单网牵引的多个连续组进行干燥，其中接触干燥气缸置于上排，倒排吸气缸置于下排或相应的对角线或垂直排。在该方法中，通过干燥网将纸幅压靠在接触式烘缸的加热面上，并且使纸幅在每个组中以单网牵引从一个支撑相同的烘干线接触干燥滚筒到达反转吸气滚筒上方的下一个接触干燥滚筒。从其下表面侧穿过干燥部分的整个长度，纸幅通过接触干燥滚筒干燥。纸幅作为一个封闭的抽签从单组抽取传递到下一组。借助于具有曲率半径D2 / 2的所述反向吸气缸将纸幅引导，同时将纸幅放置在外曲线侧的干燥网上，所述曲折半径选择为D2 /2≈250... 1000 mm，最好是D2 /2≈500... 800mm，因为纸幅被放置在外部曲线的侧面，因此纸幅保持与干燥丝恒定接触，借助于离心力的作用压力差在所述反向抽吸圆筒的整个内圆周上延伸，并且在纸幅的下表面上输送潮湿介质，优选潮湿空气和/或水雾，以均衡纸幅在z方向上的水分分布。

摘要： Method and device in a multi-cylinder dryer of a paper machine in the threading of the paper web, said threading taking place substantially without a system of threading ropes. The web is passed along a meandering path, in twin-wire draw, over drying cylinders (10A,10B) and, in single-wire draw, on a drying wire (11), over drying cylinders (10 ;10') and leading suction cylinders (20,20') or rolls (20,20'). The leader (S) is guided by means of air blowings (F 1 ) extending across a substantial proportion or the whole of its width (L i ), said air blowings (F 1 ) being applied from the doctor beam (12) to the area (K) of the by of its doctor blade (14) at a certain small angle (B) in relation to the plane of the doctor blade (14).
