A method of producing paper-pulp raw material, where disintegrated pulp wood is cooked in a cellulose digester with caustic soda, or in some corresponding cooking process, to produce paper pulp, or wherein said pulp wood is ground to produce groundwood pulp. The invention is characterised in that the raw material is comprised of pulp wood splits (15) which are produced by splitting the wood in its axial direction with the aid of a wood splitter, with the fibres lying essentially in the plane of the split; in that the splits (15) are given a thickness of about 3-10 millimetres; and in that the splits are passed between several mutually sequential rolls (17-20; 27-29) such as to bend or flex said splits forwards and backwards and therewith cause knots present in said splits to fall therefrom. |
