Abstract (en)
[origin: WO03012201A1] The invention relates to a method and an apparatus for the dosage of a binding agent. The invention relates to the manufacture of core board in particular, wherein fibres are bound together by supplying a slurry containing a binding agent, such as starch to the suspension, which has been fed onto the wire, or to the web being formed. According to the invention, the binding agent slurry is fed from feeding units installed above the wire (1), such as jet pipes (10), which are arranged sequentially at different points in the direction of travel of the wire. The jet pipes (10) can be separately adjustable, and they can be used to feed the binding agent throughout the couching of fibres onto the wire to provide an even distribution of binding agent in the direction of thickness.
