Abstract (en)
[origin: EP0545886A1] The invention relates to a method for draining, in particular pre-draining, wire-supported fibre/water suspensions passed over drainage elements, preferably foils, in particular for paper manufacture. The invention is characterised above all in that, for influencing, in particular evening out, the fibre distribution or the turbulence energy, the wire-supported suspension or fibre material web is passed over expediently at least two mutually spaced drainage elements, preferably foils, while these elements are at least partially set into vibrations. The invention also relates to devices or installations for carrying out these methods. <IMAGE>
