(3) When molding is performed using a mold, seizure occurs between the paper stock and the mold, making it difficult to take out the molded object, and the molding process tends to be large-scale.

Therefore, the present invention addresses the above-mentioned problems and provides a method of manufacturing Japanese paper, etc., which can be molded using an hour wheel and which is less likely to cause mold parts to be molded, using a water-containing sheet such as Japanese paper. The object of the present invention is to provide a method for manufacturing a shaped object using a hydrous notebook.

[Means for solving problems]

In order to achieve the above object, the method of manufacturing a modeled object using a water-containing sheet such as Japanese paper according to the present invention involves molding an object with a water-absorbing material to form a mold, and forming an inner surface of the mold. A water-containing wet sheet is placed on the inner surface of the water-containing wet sheet, and one to a plurality of sheets impregnated with an adhesive are polymerized and pasted on the inner surface of the water-containing wet sheet to form a polymer sheet. After drying and integrating the polymer sheet, the above-mentioned formwork is attached. It consists of a structure that can be removed to obtain a modeled object.

Here, in the above configuration, the object is a natural object such as a stone or a seashell, a processed product of the natural object, or an artificial object, and the moisture-containing wet sheet is Japanese paper or horse dung paper. The material-impregnated sheet is made by impregnating, spraying, or coating Japanese paper or horse dung paper with an adhesive such as Funori, and the drying method is usually natural drying.

[Effect]

Next, the operation of the method for manufacturing a shaped object using a water-containing sheet such as Japanese paper of the present invention will be explained based on the above configuration.

The method for manufacturing a shaped article of the present invention is carried out in the production of a shaped article such as a lighting shade such as a desk lamp or an ornament.

According to the manufacturing method of the present invention, the moisture in the wet sheet is naturally absorbed by the water-absorbing material molded into the shape of natural stone, etc., and the formwork and the sheet are naturally separated by drying. However, the pattern of the above-mentioned natural object is formed on the surface thereof, and it acts so that a certain shaped object can be manufactured.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments embodying the method of manufacturing a shaped object using a water-containing sheet such as Japanese paper of the present invention will be described with reference to the drawings.

Here, Figs. 1 to 6 show examples of the present invention, Fig. 1 is a perspective view of an object, Fig. 2 is a perspective view showing a state in which plaster is applied to the object, and Fig. 3 is the same as Fig. 1. Fig. 4 is a cross-sectional view of the formwork of Fig. 2 in which a plurality of water-containing wet sheets and adhesive-impregnated sheets are superposed, and Fig. 5 shows the manufactured object. A perspective view, FIG. 6 is a perspective view of a shade for lighting, such as a desk lamp, made using the manufactured object.

The method for manufacturing a shaped article of this embodiment employs a lighting shade such as a desk lamp as the shaped article, and consists of the following five steps.

(1) A first step of molding the object 11 with a water-absorbing material to form a mold 12, (2) A second step of placing a water-containing wet sheet 13 on the inner surface of the mold 12, (3) a third step of sequentially polymerizing and pasting one to a plurality of adhesive material-impregnated sheets 14 on the inner surface of the water-containing wet sheet 13; (4) the above-mentioned water-containing wet sheet 13 and adhesive material-impregnated sheet 14;
．． A fourth step of drying and integrating the polymers 15 of 14, . As the object 11, a natural stone having a shape suitable for the size of a lighting shade such as a desk lamp is used.

The formwork 12 is made of plaster. That is, the formwork 12 is formed by applying plaster to a substantially equal thickness around the natural stone, to a part (or the whole part) that has a design value as a shade for lighting such as a desk lamp, and then drying the mold. are doing. Here, an edge material 21 such as a rubber band is wound around the natural stone 11, and plaster is applied to the position of the edge material 21 to give a beautiful finish to the edge of the formwork 12.

As the water-containing wet sheet 13, Japanese paper (Japanese paper produced in Yamaguchi Tokuji was used) was used, and the Japanese paper had sufficiently absorbed water, and the Japanese paper was placed on the inner surface of the formwork 12 so that it could be brought into close contact with it. use something

The adhesive-impregnated sheet 14 is formed by soaking Japanese paper in a solution of ``Funori'', and three sheets 14 of the adhesive-impregnated sheet 14 with the ``Funori'' attached are prepared so that they can be polymerized one after another.

For drying, use natural drying in the shade.

Next, the operation of this embodiment will be explained based on the above-described configuration. When the moisture-containing wet sheet 13 and the adhesive-impregnated sheet 14, 14, and 14 arranged on the inner surface of the formwork 12 are naturally dried, both sheets become Since the polymerized sheet 15, that is, the water-containing wet sheet 13, which is a single piece and has no adhesive applied thereto, is naturally peeled off from the inner surface of the formwork 12, so that the formwork 12 can be used without being destroyed.

The polymerization of several sheets of Japanese paper works to produce a shaped object that has the same external shape as the natural stone. Further, decorations or the like are added to the edges of the shaped article as appropriate to manufacture a shade for lighting such as a desk lamp using the shaped article as a material.

In this embodiment described above, a natural stone was used as the object, but the natural stone may be artificially processed, other objects such as shells, various objects existing in the natural world, or man-made objects. may be adopted.
