Description

[Detailed description of the invention] This invention relates to a method for manufacturing a board.

Uzukuri is a method of baking the surface of cedar boards, leaving the hard parts of the winter grain as charred, while brushing and cutting off the soft parts of the summer grain to bring out the wood grain pattern. It is becoming increasingly difficult to obtain, and it is also difficult to manufacture and very expensive.

Another drawback is that products of the same standard cannot be produced in large quantities.

The present invention aims to solve the current problems of the present invention, and an example of implementing the method of the present invention will be explained below based on the attached drawings. It is a medium specific gravity fiberboard with a rank of 15. Although the vertical and horizontal dimensions of the board can be set arbitrarily, the width W is set to 4 shaku and the length e is set to 6 shaku as dimensions suitable for use as a wall material and with good productivity.

Reference numeral 2 is a plywood board having a thickness 12 of 2 mm to 5 ml and a similar size, and both are pressed together using an adhesive as shown in Figure B to form a base plate 3.

In Figure C, 4 is a board such as a toga, which is attached to the surface of the fiberboard 1 of the IJ marking board 3 using adhesive (see diagram), and E. As shown, a sponge roll 5 is used to color the surface to a light brown or dark brown color (oil coating) 6. The coloring agent used here is a coloring agent for mixing dye-based paints (for example, the trade name Sealastane), and a color-preventing sealer is then applied (spray application). It is possible to cut into a single plate 8 with a length of 0.5 shaku. (See Figure F) Figure 2 shows the process of fabricating a single plate 8t created as described above, where the single plate 8 is indicated by the arrow G).
In the process of being sent in from the (b) direction and sent out in the (b) direction, the b-making process is performed. Here, 10 and 10', 11 and 11', 12 and 12', 13 and 13', 14 and 14°, 15 and 10', 16 and 16' are sequentially fed while holding the single plate 8. There are a pair of feed rollers that are vertically opposed to each other so that the feed rollers are rotated.

Reference numeral 17 denotes a wire brush which is horizontally disposed at the initial position, and brushes the single board 8 in the direction of the grain of the single board 8 by co-currently rotating in the direction of the arrow (-), thereby scratching and scratching the surface. Next, 18 and 19 are vertically arranged wire brushes for brushing the surface of the single plate 8 in the horizontal direction. The rotation directions of 19 are clockwise or counterclockwise) and (e).

The wire brushes 18 and 19 are of a hard texture, but the wire brush 20 of a soft texture is also used in the vertical axis state.
and 21 are arranged, and the time R1 or counterclockwise direction (towards) is provided.
and (g) are different.

It has a V shape so that it can rotate in the direction. Reference numeral 22 denotes a nylon brush disposed on the horizontal axis, which is rotated countercurrently in the direction of the arrow (g) to perform final polishing.

FIG. 3 shows a single plate 8 which is processed using molders 25a and 26b, and vertical grooves 26 are formed on both sides in the length direction.
a, 266 is drilled, and the groove type is simultaneously machined with a tongue, where 27 is a male tongue provided on the side of the groove 2612, and 28 is a male tongue provided on the side of m 26b. This is a groove provided in the groove. During this tongue processing, the male tongue 27 is formed exclusively on the fiberboard, whereas the groove 2 is formed on the joint surface between the fiberboard and the plywood as the base material. It is.

FIG. 4 shows the inside of the single plate 8 using a double-end tenor (not shown), etc., and horizontal grooves 29a, 29b, 29c,
By drilling ..., a multi-tube block S1,
S2, S5... (in the illustrated example, there are 5 parts) K-divided, and both ends are processed with a tongue, 30 is a male tongue provided on the side of 29a, 31 is a +4"9/ This is a tongue groove drilled on the side.

In the above embodiment, the inside of the single plate is made up of multiple cylinder blocks Sl and S.
2. I explained what was divided into S5...
It can be used without dividing. Furthermore, although we have explained that the dye coloring is applied to the plywood board 4 after pasting it on the plywood 3, it is also possible to color the plywood board 4 with dye in advance before pasting it on the plywood board 3. It can be carried out in the same way. Although the dye to be used is described as a coloring agent for mixing dye-based paints, it may be a coloring agent for mixing pigment-based paints, or it may be dyed using other chemicals. Within the range.

In the present invention, medium-specific gravity fiberboard is used for the plywood, which is inexpensive in terms of price and easy to process, but asbestos board, gypsum board, etc. can also be used. In addition, the board to be attached to the surface of the fiberboard should have a small amount of grain and have distinct summer and winter colors, and suitable materials include Japanese cedar, Japanese cedar, Japanese cypress, and Japanese cypress.

The present invention is realized as described above, and the fiberboard stool #J has a heavy feel without causing any cracks on the surface, and has multiple acoustic effects, sound insulation, and increased heat insulation. , and the plywood on the back is extremely effective in preventing warping and twisting and reinforcing strength.

Furthermore, since the color of the dye on the board can be freely designed under certain conditions, it is possible to mass-produce products with the same color shade, and by using board or fiberboard, the entire product can be changed. can be made at low cost.
