Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper plywood chip having a colored draft pattern and a decorative image formed using the paper plywood chip.

[Prior art]

A modeling plate material having a cross-section with a colored draft pattern and a method of forming a modeled object using the same are described in detail in Japanese Patent Publication No. 35671/1983 filed by the present applicant.
Briefly, a plurality of pieces of paper of different colors are stacked, a resin-based adhesive is infiltrated into each piece of paper, and each piece of paper is bonded together with this adhesive, and a plate material for modeling with a colored striped pattern on the cross section is created. After engraving etc. on this modeling board material to make it into a single shape, a transparent resin is coated on the entire surface and penetrated, and then hardened to obtain a modeled object with a colored striped pattern. It is.

Modeling materials with such a structure are made of paper and integrated using resin adhesive.
(1) It is easy to process with a knife, and even if it is over-sharpened, it is easy to repair. (2) By using the colors of paper, objects with colored stripes can be formed without the need for skill. It has the following advantages.

[Problem that the invention seeks to solve]

As mentioned above, although paper is used as the material for modeling and processing is relatively easy, it takes a certain amount of creative creativity to create and finish a complex object from a board. Strength and skill are required. When it comes to large-sized objects, the amount of materials used and, therefore, the cost of production cannot be ignored.

The present invention takes the above-mentioned points into consideration and attempts to solve the problems by making the modeling material into chips.

That is, an object of the present invention is to provide a paper plywood chip and a technique for forming a decorative pattern, which requires no special skill, requires less material, and can effectively form a decorative pattern.

A brief overview of typical inventions disclosed in this application is as follows.

In other words, a plurality of pieces of paper of different colors are layered, a resin-based adhesive is infiltrated into each paper piece, and a resin-based adhesive is infiltrated into each paper piece, and the paper is bonded with this adhesive to form plywood.The main surface of the sheet is then thinly shaved diagonally to create a curved cross section. It is made of small pieces (chips) that have colored striped patterns in the shape of mochi and wood grain, and a plurality of these small pieces are arranged and glued on a flat or three-dimensional surface to form a predetermined decorative pattern and to decorate the entire surface. Some products are cured by coating them with a transparent resin.

[Effect]

By forming conventional paper plywood into small pieces, the construction of decorative patterns or shaped objects becomes easy, no skill is required, and material costs can be reduced, thereby achieving the above object.

〔Example〕

Commercially available thin western paper (full size,
Prepare pieces of paper dyed in several different colors using Japanese paper (four-cut, eight-cut) or Japanese paper. These pieces of paper should be completely dyed on both sides of the paper, right down to the center, in order to make the most of the color of the cut cross section, and should be relatively thin so that the liquid resin can penetrate well. For example, 20 to 30 or more of the above paper strips of the same color are stacked one upon another according to an appropriate color distribution to form one board. When pasting pieces of paper together, adhesive is applied to each piece of paper and the pieces of paper are successively overlapped. The adhesive material is one that completely adheres to pieces of paper and dries quickly, does not harden after drying, is soft, colorless and transparent with no foreign body feeling, and does not change color, and has an adhesive strength that does not change the color of the paper. Stir and mix a chemically synthesized glue (for example, Arabic glue, etc.) and a vinyl acetate resin emulsion adhesive (commonly known as woodworking bond), and use a ruler etc. to uniformly and thoroughly penetrate the paper. After applying the coating so that the
Crimp. For example, by stacking 30 pieces of paper, a paper plywood material 2 having a constant thickness (approximately 5 mm) and colored stripes on the side cross section 3 is obtained as shown in FIG.

The paper plywood material 2 obtained in this way has paper as the core material and the adhesive part is not fixed, so it can be easily cut, cut out, or
It can be processed by cutting, chopping, etc., and can be shaped into a desired shape.

FIG. 2 is an enlarged sectional view showing a form in which the paper plywood material 2 is processed to produce paper plywood chips.

For processing the paper plywood material, a round-blade cutter 4 having a curved cross section and a blade 4a at the tip, as shown in FIG. 3, is used, for example.

As shown in Fig. 2, by repeatedly cutting parallel to the main surface 1 of the paper plywood material 2 by applying force in an oblique direction (angle θ) using the cutter 4, thin pieces with a curved cross section can be obtained. (Chip) A large number of 5's are obtained.

One piece of the chip obtained in this way has a tongue-like wood grain striped pattern, as shown in Fig.
The -A cross section is curved into a crescent shape as shown in Figure 4A.

When processing such paper plywood chips 5, if you use a cutter with a large degree of curvature in the cross section, you can obtain chips with a large width dimension, but if you use a cutter with a small degree of curvature in the cross section, you can obtain chips with a narrow width. You will get chips. Alternatively, you can use a cutter (triangular chisel) with a V-shaped cross section to create a V-shaped cutter as shown in Figure 5.
A chip 6 with a shaped cross section is obtained.

Furthermore, if the angle θ of the cutter with respect to the main surface of the paper plywood material is small, chips with a long vertical dimension can be obtained. On the other hand, if θ is large, chips of the same size can be obtained.

This kind of cutter processing can be done by using multiple cutters fixed to a jig at the same time.
It is possible to produce a large amount of chips in a short period of time.

When producing the first paper plywood material 2, paper plywood chips with a desired color combination can be produced by appropriately selecting the color combination of the colored papers to be piled up.

FIG. 6 shows an example in which a decorative image is formed on a flat surface using paper plywood chips produced by the method described above.

Reference numeral 7 indicates a substrate made of paperboard or board material, and 8 indicates a paper plywood chip bonded onto this substrate.

Paper plywood chips are arranged according to the desired pattern shape as shown in the figure, and after bonding to the substrate with an adhesive on the coated back side, a transparent liquid acrylic resin diluted with thinner etc. is applied to the chip surface. and dry. In this way, a decorative image having a cross pattern as shown in the figure is obtained on a substrate such as paper or board.

FIG. 7 shows an example of a pendant manufactured using paper plywood chips.

For example, a felt material is used for the substrate 9, and paper plywood chips 10 are arranged, for example, in a radial manner on this substrate without gaps. In some cases, the chips will be doubled or tripled. The chips around the chip are cut into the desired shape, and a transparent liquid resin is applied to the surface to create a pendant shape. Attach metal fittings such as clips and chains to the back to complete the pendant.

FIG. 8 shows an example of a decorative painting made using paper plywood chips. The birds, flowers, trees, etc. shown in the figure are all made by selecting chips with a color tone and shape that matches their respective colors, placing them on a board that serves as a substrate, joining them with adhesive, and hardening them with transparent resin. .

〔Effect of the invention〕

According to the present invention described in the embodiments above, the following effects can be obtained.

(1) Paper plywood material can be easily processed using cutters, etc., and chips with striped patterns of desired colors can be produced in large quantities with desired dimensions.

(2) Such paper plywood chips can be easily placed and adhered to a substrate such as paper or board without requiring special skill, and the cost required for this is low.

(3) Because it is easy to process and has an excellent finish, it can be widely used as a material for beginners' decorative patterns and decorative paintings, and as a material for home hobby handicrafts.

Although the invention made by the present inventor has been specifically explained based on examples above, the present invention is not limited to the above-mentioned examples, and various changes can be made without departing from the gist thereof.

For example, the substrate to which the paper plywood chips are attached is not limited to a flat surface, but can also be used to create various shapes of boxes and decorative objects by using three-dimensional surfaces, including curved surfaces.
