2. Description of the Related Art Conventionally, in the papermaking process, a wet web which has been dehydrated by a wire part is received and carried to a press part, and water is further squeezed through press rolls. Papermaking fabrics are used to send. Today, in order to meet the demands for improving the production efficiency by improving the quality of paper and increasing the speed of papermaking, we have developed papermaking woven fabrics with excellent properties such as smoothness, stock support, dewaterability, and strength. Development is required.

[0003] In order to improve such performance, particularly smoothness and stock support, it is ideal that the warp and the weft constituting the papermaking fabric have the same height when the papermaking fabric is finished. Due to factors such as the diameter of the warp and the weft, the weaving method, and the heat setting, the height of the knuckle caused by the weaving of the warp and the weft increases at the time of finishing, and the weft protrudes above the warp (papermaking surface side). Sometimes. As a result, there is a problem that the surface properties of the papermaking fabric are reduced, and the smoothness and the stock support are also reduced.

As a method of solving such a problem, the diameter of the warp or weft constituting the papermaking fabric is reduced and the density is increased to increase the number of supporting points of the paper layer, and the knuckle portion generated by the weaving of the warp and the weft is formed. A method of suppressing the height can be considered, but if the yarn diameter of the warp or weft is reduced,
There is a conflicting problem that the wear resistance is reduced. vice versa,
When trying to improve the durability by increasing the diameter of the warp or the weft, the height of the crimp caused by the weaving of the warp and the weft is increased, the surface property of the papermaking fabric is reduced, and the smoothness and the stock support are reduced. As a result, the dewatering efficiency is reduced as a result.

Therefore, conventionally, the smoothness of the papermaking fabric has been improved by polishing the surface of the papermaking side fabric layer of the papermaking fabric. However, in the conventional papermaking fabric, the amount of polishing is as small as about 10 to 20 μm because, in view of the strength of the papermaking fabric, it is avoided that the polishing is performed more than necessary from the viewpoint of maintaining the strength. Only an amount of surface polishing was performed, and it was still insufficient from the viewpoint of improving the smoothness of the papermaking fabric.

In the method for processing a papermaking fabric according to the present invention, the papermaking fabric before polishing is hung between two rolls and run at a constant orbital speed, and the papermaking surface of the papermaking fabric before polishing is applied. The polishing roll is rotated and brought into contact with the side fabric layer. The method for processing a papermaking woven fabric according to the invention of claim 8 is such that the polishing roll used for surface polishing is not fixed, but is rotated at a fixed number of revolutions and brought into contact with the papermaking woven fabric. This makes it possible to more appropriately adjust the surface polishing of the papermaking surface side fabric layer. That is, as shown in FIG. 4 (A), when the polishing roll 6 is rotated at a constant rotation speed in the same direction as the circumferential direction of the papermaking fabric 1, it becomes easy to appropriately adjust the polishing amount.
It is preferable because it can prevent excessive shaving.
As shown in FIG. 4 (B), when the polishing roll 6 is rotated at a constant rotation speed in a direction opposite to the circumferential direction of the papermaking fabric 1,
The polishing amount is about 1.5 times, and the target polishing amount can be reached in one round. As a result, the working time can be shortened, which is preferable.

When the papermaking fabric of the present invention has a multilayer structure, the papermaking side weft constituting the papermaking side fabric layer is woven into the warp, so that the papermaking side weft is interposed between the adjacent papermaking side weft. In order to compensate for the formed depression, an auxiliary weft having a smaller diameter than the papermaking surface side weft can be woven between adjacent papermaking surface side wefts. The incorporation of such auxiliary wefts compensates for the above-mentioned depressions. As a result, it is possible to improve the supportability and smoothness of the stock without substantially changing the woven fabric structure, and to produce paper having excellent surface properties. Furthermore, the shape of the papermaking fabric of the present invention is not particularly limited, and in addition to being endless,
It can also be endless.

According to the papermaking fabric of the present invention, the surface is polished more than before, thereby improving the surface properties and smoothness as compared with the conventional papermaking surface fabric. The strength in relation to the connecting part of the papermaking fabric can still be maintained. Further, since the net thickness of the papermaking fabric can be reduced without changing the wire diameters of the warp and the weft, dewatering efficiency can be improved and papermaking can be performed efficiently. Further, according to the method for processing a papermaking fabric of the present invention, it is possible to simply and economically carry out polishing using existing equipment without using any special device or means. Further, according to the processing apparatus of the present invention, the process up to the target thickness can be known, so that the polishing conditions can be set earlier.
