<p>A method of producing core raw paper is provided that prevents corrugation cracking, corrugation cutting or breakage from occurring during corrugating operation using a corrugating roll, prevents the wearing of the corrugating roll, reduces the driving power consumption and noise, is capable of uniformly and efficiently coating the core raw paper with wax, and does not pollute facilities such as a paper machine. A method of producing core raw paper for corrugated boards coated with wax by a paper machine having a plurality of driers, comprising the steps of spraying, as at (S), the surface of a drier (C8) with a dispersion containing the wax, changing the wax into oil on the surface of the heated drier (C8), and pressing the surface of the drier (C8) against core raw paper (100) to thereby transfer the oil-changed wax from the surface of the drier (C8) to the core raw paper (100).</p> |
