Abstract
Method and device in the manufacture of paper or board for dewatering of the paper web (W) that is being manufactured. The paper web (W) is transferred from the forming wire (10) onto the wire (80) in the drying section while constantly on support of a fabric that receives water, a transfer febric, or of any other, corresponding transfer surface (105') as a closed draw, at a particularly high speed, which is, as a rule, higher than about 25...30 m/s. Dewatering of the paper web (W) is carried out by means of two subsequent extended press nips (NP1, NP2), whose length (z) in the machine direction is larger than z > about 100 mm. After the first extended press nip (NP1), through which the web is passed between two fabrics (20, 30) the web is transferred by means of a suction roll (40) to a single upper fabric (40) passing through the second extended nip (NP2), which has a smooth faced counter roll (105) in a lower position. <IMAGE>
