Abstract

In a method for manufacturing multi-ply web by means of a paper or cardboard machine, a prefiltered web (W1) is formed on a first wire (3), and a second web (W2) formed on a second wire (4) is brought on top of said web. The wires (3, 4) are brought against each other by means of a reversing roll (2), at which the second wire (4) travels round the roll (2) and is set on top of the first wire (3) in such a way that the webs (W1, W2) form the joined layers of the multi-ply web after said point. An additional roll (1) on the side of the first wire (3) lies against the reversing roll (2), said rolls (1, 2) being mounted in such a way that a press nip (N) is formed therebetween. The rolls are loaded against each other using desired force for effecting a suitable line pressure that influences the bond between the webs (W1, W2). By means of the line pressure a movement (A) of water in the web layers and a movement of fine substances therewith is caused at the interface (W12) of the web layers towards one of the rolls at the press nip (N).
