Abstract (en)
[origin: WO8404115A1] At the making of multi-layer paper it has been a problem to bringabout sufficient adhesion between the layers in an efficient and economic way. According to the invention this problem is solved, in that a cellulose pulp with a beating degree exceeding 40<o>SR in an amount of at maximum 10 g/m<2> is inserted between the layers.
