Abstract (en)
[origin: EP0881329A2] After a film of a minute fiber suspension is formed on the surface of an applicator roll 22 disposed at a press section of a paper machine, the suspension is applied to at least one surface of a wet paper web 4. The weight concentration of minute fibers in the suspension used is set at 3.0 to 5.0%, the amount of minute fibers applied to the surface of wet paper is set at 0.2 to 2.0 g/m<2> per one surface of the wet surface 4, and the amount of paper strength increasing agent is set at 0.5 to 2.0 g/m<2> per one surface of the wet surface 4. A paper strength increasing agent may be mixed with the suspension of minute fibers prior to forming the film on the roll 22. <IMAGE>
