The wet paper web forming process will be described along the flow of the raw material liquid based on the same drawing. The raw material liquid 2 supplied from the head box 1 onto the wire 3 continuously running is provided below the wire 3 running. Further, the dehydrating foil group 4 causes a downward dehydrating action, and gradually becomes a form of the wet paper web 2a while increasing the concentration of solids (fiber + filler) in the raw material liquid 2. The wet paper web 2a thus formed is depressurized (vacuum) dehydrated by a device called a suction box 5 to finally form a paper layer. The formed paper layer is further subjected to decompression (vacuum) dehydration by the suction roll 6, and then the felt 8 running at the same speed from the running wire 3 is run.
It is picked up by the suction pickup roll 7 and moves to the pressing step of the next step. In this pressing step, the formed wet paper is squeezed by the water squeezing action by sandwiching it between two rolls (for example, 9 and 9 ') via the felt 8 or the like and applying pressure to form a stronger paper layer. After that, the process proceeds to the next drying process (not shown).

の製造方法を提供しようとするものである。In the paper manufacturing method shown in FIG. 11, the wet paper web is formed only by the backwash action by dehydration in the foil group which is the dehydration device and the downward unidirectional dehydration action. Due to such factors, there is a difference in the content ratio of the fine fibers and the filler on the front and back of the paper, and the paper easily curls,
In addition, there are problems such as different ink receptivity on the front and back sides.
To improve this, there are on-top formers, twin wire formers, etc. that sandwich the raw material liquid with two wires for dehydration, but there is no function to control the content ratio of the front and back layers from the outside, and it is still complete. The front and back symmetrical paper is not manufactured. Further, in the conventional manufacturing method, since the filler is mixed with the raw material liquid to make the paper, the filler is present even inside the formed paper layer, and there is a problem that the hydrogen bond between the fibers is hindered and the strength is lowered. .. On the wet paper surface as a conventional improvement method,
Although a method of spraying or spraying white water flowing out from the wire screen or a mixed solution containing a filler component has been proposed,
Since the pulp fiber length contained in white water has a relatively large distribution, it has a front and back symmetry, but has a drawback of lacking surface smoothness. The present invention is intended to provide a method for producing paper which can solve these problems.

のに比べ平滑度が向上する。As described above in detail, according to the present invention, the amount of fine fibers or the content of filler on the surface of the paper can be controlled from the outside so that the content on both sides can be made equal, thus curling can be reduced. In addition, since the unicellular alga has a uniform aspect ratio (L / D) and algal length (L), the surface of the paper layer is smooth. Furthermore, since the filler content inside the paper layer can be made substantially zero, hydrogen bonding between fibers is not hindered and various strengths are not reduced. In addition, the bond strength is increased by the fine fibers,
The surface strength is increased, and printing defects due to paper dust on the printing press are reduced. Furthermore, since the filler is not mixed in the raw material and is sprayed on the wet paper, the yield is good and the treatment load of white water can be reduced,
In addition, it is possible to produce paper which has many advantages for a paper machine and a printing machine, such as abrasion of the dehydration member. Further, the unicellular algae can be selected to have an arbitrary aspect ratio (L / D) and algal length (L) by selecting the type, and the unicellular algae can be selected according to the surface roughness of the paper layer structure. Since the mixing ratio and the coating amount can be determined, the smoothness is improved. In addition, by mixing unicellular algae with different aspect ratios, the unicellular algae are applied in the form of filling the irregularities on the surface of the paper layer, respectively, resulting in smoother than single unicellular algae The degree improves.
