Abstract (en)
The present invention refers to a procedure for the manufacture of a multi-layer pulp product, preferably paper or cardboard. Said procedure consists of applying a filler between at least two layers of fibre material in motion prior to the final joining together of them. The filler is preferably of inorganic origin, though it can consist of organic components, and calcium sulphate is preferably used. <IMAGE>
