Method for manufacturing a paper or board web and a paper or board machine

摘要

The present invention relates to a method for manufacturing a paper or board web. Stock is fed from a headbox (100) to a wire section (200), in which water is removed from the web (W) and from which the web (W) is passed to a press section (300), in which water is pressed out of the web (W) and after which the web (W) is dried in a dryer section (400) and reeled by means of a reel-up (800). According to the invention, additives, fillers and/or fines are fed into the stock of the surface layers of the web (W) in order to reduce the pore size distribution of the web in the surface layers so as to substantially correspond to a precoated web. The invention also relates to a paper or board machine which is characterized in that it comprises means for feeding additives, fillers and/or fines into a fibre stock such that an uncoated web substantially corresponds in its properties to a precoated web. <IMAGE>
