    • A web-forming section of a paper or board machine comprises a first web-forming unit in which a first fibre layer (W 1 ) is formed on a first wire (10), a second web-forming unit in which a second fibre layer (W 2 ) is formed on a second wire (30), and a couch shoe (39) over a curved deck (40) of which the fibre layers (W 1 , W 2 ) are guided for joining them together. The second fibre layer (W 2 ) is brought to the couch shoe (39) at an angle (α) of less than 20°, advantageously less than 15° in relation to the approach direction of the first fibre layer (W 1 ). The couch shoe (39) is provided with underpressure and the radius of curvature of its deck (40) is usually larger than the radius of curvature of a guide roll (38) preceding it. By means of the couch shoe, the fibre layers can be joined together wetter than usual.
    • 纸或纸机的纸幅形成部分包括第一纸幅形成单元,其中在第一丝线(10)上形成第一纤维层(W 1 N 1),第二幅材形成单元 单元,其中在第二丝线(30)上形成第二纤维层(W SUB 2),以及在弯曲甲板(40)上方的沙发(39),其中纤维层(W < 引导它们连接在一起。 第二纤维层(W 2 2)相对于第一纤维层(39)的接近方向以小于20°(有利地小于15°)的角度(a)被带到沙发(39) 纤维层(W 1 N 1)。 沙发鞋(39)具有负压,并且其甲板(40)的曲率半径通常大于其前面的导辊(38)的曲率半径。 通过沙发鞋,纤维层可以比通常更湿润地连接在一起。
