Abstract

Method for forming multiply paper or board product, where all the plies are formed by means of roll forming of the type where the fibre suspension jet is introduced in the twin-wire nip at such a speed that the outer wire of the tensioned wires (2; 10; 17) is deflected while maintaining a substantially constant tension during the deflection of the outer wire, by the fact that the outer wire is supported by a rotating support (5; 14; 19), at least one of which being resiliently or displaceably mounted to compensate for said deflection. The forming of each ply occurs over only one forming roll (4; 11; 18), wherein the wire winding angle ( alpha ) over the forming rolls is at least 110 DEG , that the forming rolls are located alternatingly in two planes, that for the forming roll (rolls) in the upper plane the wires leave the roll in a lower quadrant (G, H) where the paper web follows the outer wire, and for the forming roll in the lower plane the wires leave the roll in an upper quadrant (E, F), where in this case the paper web also follows the outer wire.
