Abstract

A method and apparatus for manufacturing multilayer filter paper on an inclined wire former. The former is provided with a forming wire (4) having an inclined wire portion (10) and a substantially horizontal wire portion (12). Stock is delivered to the former from a multichannel headbox (14) in which the flow channels (18) are arranged one above the other in such a way that the upper wall (16n) of one channel (18n-1) forms the lower wall (18n) of the flow channel on top of it, the flow channels leading to subsequent forming zones in each of which a layer of fibers superimposed on the layer formed in the preceding forming zone, is to be formed. The inclination angle ( alpha ) of the inclined wire portion decreases gradually in the travelling direction of the wire.
