Abstract (en)
[origin: WO9312292A1] A twin-wire former is used to produce a web of paper or cardboard. Two wires (endless wire loops 11 and 12) form together a twin-wire zone, in which the first wire (12) runs over fixed rails (28', 28) mutually spaced in a dehydration box (18), as well as the other wire (11) over a few rails (27) located opposite the fixed rails (28), supported on compliant elements (springs 24, pneumatic pressure cushions or the like) and capable of being pressed with a selectable force against the other wire. A closed wire supporting surface (9) is arranged before the rails (27) in one of the wire loops (27). A secondary pulp inlet (10') may be arranged before the closed wire supporting surface (9).
