发明名称 Method for manufacturing a paper or board web and a paper or board machine
摘要 A method for manufacturing a paper or board web in which 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 is structured for enabling the feeding of additives, fillers and/or fines into a fiber stock such that an uncoated web substantially corresponds in its properties to a precoated web.
