<p>The invention concerns a method and an improved paper machine for making a surface-sized paper web. Pulp is supplied from the headbox (100), wherein additives and/or fillers and/or fines are admixed into the pulp, to the wire section (200), where water is removed from the web (W). From the wire section (200) the web (W) is guided to the press section (300) to press water from the web (W). The web (W) is then dried in the front drying section (400), whereupon the web (W) is surface-coated in the coating section (500) and dried in the post-drying section (600). Finally, the web (W) is reeled by a reeler (800). According to the invention, in the headbox (100) starch and optionally hydrofobic size are admixed or layered into the pulp to be supplied to the wire section (200), so that on at least one side of the web (W) an essentially dense surface is formed, on which in surface-coating a coating paste is spread out, which has a high dry matter content, whereby a bond is achieved in direction z inside the web (W) in between the base paper and the surface-coating layer spread out on the surface. The invention also concerns a surface-sized paper, wherein according to the invention there is a bond in direction z between the surface-coating layer and the base paper.</p> |
