は産業廃棄物として処理せざるを得す、その結果。<Prior Art> In the production of various conventionally known wet-laid nonwoven fabrics, there have been requests to change the predetermined width of the product, but the suspension dewatering device section has not been attached to the short-mesh paper making section, or has been attached. However, due to structural and functional limitations of the equipment, paper is always made using the full width of the equipment, and the paper is sent as is to the mechanical processing equipment after the paper making section, and in the finishing process unnecessary parts at both ends are cut off. It was adjusted to width. As a result, the unnecessary parts at both ends have to be disposed of as industrial waste.
不織布原料の収率低下を招かざるを得なかった。This inevitably resulted in a decrease in the yield of nonwoven fabric raw materials.

いることができない。In addition, since regular processing is carried out on the unnecessary parts as well as the necessary parts of a predetermined width, the power of the dewatering vacuum pump and the power and steam in the subsequent drying and finishing processes are wasted. Become. Furthermore, a method is known in which the unnecessary portions are cut using wet paper. In this case, the wet paper was dehydrated by a suction box over the entire paper width to increase its strength, and then the wet paper was cut by blowing it away with a water jet from a water jet nozzle. However, this method cannot be used in the case of wet paper with a strong tenacity because it is difficult to cut it.

排除することができる。In order to eliminate the drawbacks of the conventionally known paper making methods, in a method for producing a wet-laid nonwoven fabric using a short wire paper machine, a flexible material is placed on both side edges of the short wire in the paper making section of the short wire paper machine. Place the Nordeckel device between the sexual apron sheets,
A method is known in which the paper width of a short-mesh paper machine is adjusted by changing the distance between the Nordeckel devices on both sides. By using this method, wet paper having a predetermined paper width can be obtained, and the drawbacks of conventionally known methods can be eliminated.

用することはできない。However, in the method using the Nordeckel device and the apron sheet, the apron sheet is simply clamped and fixed between the Nordeckel device and the short screen, so there are There will be a small gap between the net and the net. The raw material suspension leaks from the gap, and the leaked part becomes a lump and protrudes from both ends of the wet paper, forming the wet paper.
As a result, wet paper made using this method had to have both end surfaces in a disordered state. It is also possible to prevent the leakage of the raw material suspension by strongly pressing the apron sheet against the short screen using a Nordeckel device, but this method is undesirable because it obstructs the running of the short screen, and this method cannot be adopted. .

が形成される。As shown in FIG. 1, in a short screen machine, a certain amount of raw material suspension 2 stored in a raw material suspension tank 1 is transferred to a short screen (wire) 3 running in the direction shown by the arrow in FIG. Flows into ±. Since the short screen 3 is provided with a large number of holes, the short screen 3
The above raw material suspension 2 progresses to the right in FIG. 1 while being gradually dehydrated. At this time, as shown in FIG. 2, Nordeckel devices 6 are placed on both side edges of the short screen 3, sandwiching the flexible Ω apron sheet 7. Said apron sheet 7
is used to prevent the Nordeckel device 6 from damaging the running short net 3. In addition, there is 1 on the downstream side of short net 3.
More than one dehydration suction box is provided (4a, 4 in Figure 1).
2 suction boxes for dehydration shown in b], most of the moisture is removed from the raw material suspension by the suction boxes for dehydration, and the wet paper 5 is

長さおよび相対位置が定められる。In order to carry out the method of the present invention, the apron sheet 7 is formed so as to protrude from the Nordeckel device 6 toward the outside of the paper making section as shown in FIGS. 2 and 3, and the protruding portion is held diagonally and fixed. It is fixed by means 8. The gripping and fixing means 8 consists of a gripping member 8C that grips the protruding portion 7b of the apron sheet, a support 8a installed upright on the frame 9 of the paper machine, and a connecting bar or play 8b that connects the gripping member 8c and the support 8a. Become. It is preferable that the gripping member 8C has a U-shaped cross-sectional shape and grips the entire length of the protruding portion 7b of the apron sheet 7.One end of the connecting bar or play 8b is gripped at at least two points along the entire length of the gripping member 8C. The other end of the member 8c is attached to the top of the support column 8a. At that time, the height of the support 8a is adjusted so that the protruding portion 7b of the apron sheet 7 is inclined obliquely upward with respect to the portion 7a of the apron sheet 7 that is sandwiched between the short net 3 and the Nordeckel device 6. The length and relative position of bar or play) 8b is determined.

で維持することができる。The apron sheet 7 is made of a flexible material, such as hard rubber. Therefore, as shown in an exaggerated manner in FIG. 4, since the portion 7b of the apron sheet 7 is bent relative to the portion 7a, stress is applied to one portion 7a, causing the portion 7a to curve in a wave-like manner. . As a result, the wavy ridges 10 do not come into contact with the lower surface of the Nordeckel device 6 and the upper surface of the short screen 3, and therefore the raw material suspension is transferred to the Nordeckel device 6 and the apron sheet 70 from the inner surface 6a of the Nordeckel device 6. Also, it is possible to reliably prevent the water from flowing between the apron sheet 7 and the short screen 3. That is, the sealing performance between the parts is improved, and the liquid layer of the raw material suspension can be maintained at a predetermined paper width up to the rear end of the Nordeckel device 6.

湿紙は乾燥工程を経て紙が作られる。Further, in the present invention, the raw material suspension, which has been maintained at the predetermined paper making width and has advanced to the rear end of the no-decker device 6, spreads in the width direction after leaving the rear end of the no-detsukel device 6, and spreads across the wet paper web 5.
In order to prevent the end face from being disturbed, the Nordeckel device 6
Provides a rapid dehydration effect at the rear end of the That is, a1
By arranging the suction dewatering device 4a below the short screen 3 at the rear end of the 7-Detsukel device 6 as shown in FIGS. Gives suction dehydration effect until there is no water. As a result, the wet paper is given the same shape as it was maintained by the Nordeckel device 6, making it possible to obtain a wet paper with clean edges. If necessary, a suction dehydrator 4b may be further disposed downstream of the suction dehydrator 4a for further dehydration. After that, the wet paper goes through a drying process to make paper.

You can get beautiful wet paper. Furthermore, when wet-laid nonwoven fabric is produced by the method of the present invention, only the width required for the jM product width can be sent to the drying process, and as a result, it is possible to save on raw materials and power, and also to reduce the generation of industrial waste. This can be prevented.
