[0002]

2. Description of the Related Art In a conventional artificial precious wood, a summer wood color adhesive is applied to one surface of a dyed veneer dyed in spring wood color.
A color-processed veneer is formed by seal pressing, a large number of the color-processed veneers are laminated and laminated to form a flitch, and the flitch is sliced to form a slice veneer. The grain is expressed by the veneer and the colored adhesive. By the way, since there is a difference in shade between natural wood grain and single wood grain, it is necessary to apply seal adhesive using several kinds of colored adhesives, and to apply the colored adhesive partially even on each veneer. Or change.

[0003]

However, in the case of natural cypress, the grain portion disappears in the middle like a pseudo annual ring, but this cannot be expressed until now. The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an artificial precious tree having an appearance very similar to that of a natural cypress or the like by removing the wood grain on the way. To provide a method for manufacturing precious wood.

[0004]

In order to achieve the above object, a method for producing an artificial precious wood according to the present invention is to provide a processed veneer 2 obtained by tenderizing a dyed veneer 1 and cutting the fibers in the fiber direction.
Is formed, a colored adhesive 3 is applied to one surface of the processed veneer 2, and the colored adhesive 3 is allowed to penetrate into the cracks 4 of the processed veneer to form a colored processed veneer 5. Board 1
When a large number of adhesive veneers 6 each having an adhesive 10 applied to one side thereof are laminated, the coloring veneer veneer 5 is partially interposed at an appropriate position and laminated to form a flitch 7, The flitch 7 is sliced to form a sliced veneer 8.

[0005] Further, after the nonwoven fabric 9 colored in a wood grain is pasted on the dyed veneer 1, the dyed veneer 1 is subjected to tender rising to form a processed veneer 2 in which the fibers are cut in the fiber direction, The coloring adhesive 3 is infiltrated into the cracks 4 of 2 to form a colored veneer 5, and the dyed veneer 1
When a large number of adhesive veneers 6 each having an adhesive 10 applied to one side thereof are laminated, the coloring veneer veneer 5 is partially interposed at an appropriate position and laminated to form a flitch 7, The flitch 7 is sliced to form a sliced veneer 8.

[0006]

According to the above arrangement, the artificial nameplate of the sliced veneer 8 can be obtained which can express a pattern in which the grain has partially disappeared by the coloring veneer 5 and is very similar to a natural cypress.

[0007]

FIG. 1 is a view showing a process for forming a veneer 5 subjected to a coloring process. The dyed veneer 1 has a thickness of about 1 mm, and this dyed veneer 1 is first subjected to tenderizing as shown in FIG. 1 (b). This device uses a table 14
A metal round bar 12 is inserted into a concave portion 11 having a semicircular cross section, and a rubber roll 13 is arranged above the table 14 so as to correspond to the round bar 12. Rubber roll 13 and round bar 1
2 is adjusted in accordance with the thickness of the dyed veneer 1. Table 14 and rubber roll 1
3 is passed through the veneer veneer 1 and subjected to tender rising. The tenderizing process is performed while the dyed veneer 1 is in a wet state, and then the humidity is adjusted. When the tenderizing process is performed, the fibers of the dyed veneer 1 are cut in the fiber direction, and a processed veneer 2 having a crack 4 is formed as shown in FIG. As shown in FIG. 1D, a colored adhesive 3 is applied to one surface of the processed veneer 2 formed as described above, and is sealed and pressed to penetrate the colored adhesive 3 into the crack 4 as shown in FIG. 1E. Thus, the coloring-processed veneer 5 is formed. The coloring adhesive 3 is obtained by adding about 2 parts by weight of a coloring agent such as Dykton Brown or Yellow to the adhesive. The amount of the colored adhesive 3 applied is about 50 to 60 g / m ² . FIG. 2
Shows a state in which the bonded veneer 6 is manufactured by a normal method. The dyed veneer 1 is of a thickness of about 1 mm dyed in a pale color so as to express spring wood color, and a colored or clear adhesive 10 is applied to one surface of the dyed veneer 1,
The adhesive 10 is cured by seal-pressing through the release paper 15.

The flitch 7 is formed by laminating a large number of bonded veneers 6, and the coloring processed veneer 5 is interposed every time 5 to 30 bonded veneers 6 are laminated. In this manner, about 700 to 800 sheets of the adhesive processing veneer 6 and the coloring processing veneer 5 having a thickness of about 1 mm are laminated, and the laminate is formed by heating and pressing to form a flitch 7 as shown in FIG. Then, the flitch 7 is sliced into a straight grain to obtain a sliced veneer 8 as shown in FIG. At this time, it is possible to express a grain that partially disappears in the coloring-processed veneer 5.

Next, another embodiment will be described. As shown in FIG. 4A, a nonwoven fabric 9 adhered to a grain of wood is adhered to one surface of the dyed veneer 1 with a clear adhesive.
The stained veneer 1 to which is adhered is subjected to tender rising processing to form cracks 4 as shown in FIG. 4 (b), and the colored adhesive 3 is applied to the nonwoven fabric 9 from the surface opposite to the nonwoven fabric 9 in the same manner as in the above embodiment.
The coloring adhesive 3 is applied at a rate of 60 g / m ² to penetrate the cracks 4 to form the coloring-processed veneer 5. Using the colored veneer 5 and the adhesive veneer 6, a flitch 7 is formed in the same manner as described above, and the sliced veneer 8 is formed by slicing to obtain a straight grain. Also in this case, the grain which can be partially erased by the coloring-processed veneer 5 can be expressed. At this time, the width of the grain can be widened by the nonwoven fabric 9 and a more varied grain can be expressed.

Next, another example utilizing the feature of tenderizing the dyed veneer 1 will be described. Dyed veneer 1
A nonwoven fabric 9 is adhered to one side of the substrate with an adhesive, and the dyed veneer 1 to which the nonwoven fabric 9 is adhered is subjected to tenderizing as shown in FIG. As shown in FIG. 5 (b), a large number of the processed veneers 2 are laminated, sandwiched between an upper die 16a and a lower die 16b of a forming die 16 for a plate, and laminated and formed so as to be curved. At this time, a large number of processed veneers 2 can be integrated with an adhesive for bonding the nonwoven fabric 9. At this time, since the processed veneer 2 is in a soft state by tender rising, it can be sufficiently curved even when a large number of processed veneers 2 are laminated. Conventional 600mm
600mm was able to bend only 100mm in width of
With a width of 200 to 250 mm. The sliced veneer 8 obtained by slicing the flitch 7 formed in this manner had a bamboo pattern as shown in FIG. 5C.
