Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for manufacturing laminated wood such as laminated decorative veneer.

[Background technology]

Generally, the following method is used to obtain a veneer from low-grade logs that has the same wood texture as a decorative veneer obtained from a material with holes such as natural oak. That is, raw wood veneers are made from low-grade logs, bleached, dyed to the desired color, and then dried (humidity controlled) to form dyed veneers. Next, a plurality of these dyed veneers are laminated with adhesive and pressed using a flat mold to form the first flitch (
Next, this first flitch is sliced perpendicular to the laminated surface (straight grain slicing) to create a first sliced veneer. Next, a plurality of the first sliced veneers are laminated with adhesive and pressed using a flat mold to create a second flitch, and a straight grain slice is made to this second (2) flitch. to create a second sliced veneer. Then, the veneer surface of this second sliced veneer is given an uneven surface using a roll press or the like to form an uneven veneer, and a plurality of these uneven veneers are laminated with an adhesive, so that the mold surface is curved. A method is used in which a third flitch is created by pressing with a pair of upper and lower templates, and a laminated decorative veneer is created by slicing this third flitch parallel to the laminated surface. In the laminated decorative veneer thus obtained, the concave portions of the uneven veneer appear as conduits as conduits, and the pore portions similar to natural pore portions are expressed.

However, this method involves decolorizing and dyeing the raw wood veneer.

This resulted in poor dyeing (variation in color) and was problematic in terms of yield.

[Object of the Invention] The object of the present invention is to improve yield.

[Disclosure of the invention]

The method for manufacturing laminated wood of this invention is to stack a plurality of (3) raw wood veneers obtained from raw wood with an adhesive that is either colored in a target color or not colored without undergoing bleaching or dyeing treatment. A first flitch is formed by pressing using a flat mold, and this is sliced at a predetermined angle with respect to the laminated surface to create a thin sliced veneer, and this thin sliced veneer is glued in a target color. A plurality of flitches are laminated with an agent in between and pressed using a flat mold to form a second flitch, which is then sliced at a predetermined angle to the laminated surface to create a sliced veneer. A material veneer obtained by applying unevenness processing to the surface is prepared, and this material veneer is used as at least a part of the material veneers among the plurality of material veneers to create a flitch through a lamination bonding process. The feature is that a laminated wood can be obtained by processing this flitch.

That is, by doing the above, the colored adhesive permeates and colors the entire thin sliced veneer in the target color, so a predetermined laminated wood can be obtained without bleaching or dyeing.

Next, this invention will be explained based on examples (4) Ru.

First, the thickness is 0.8 to 1.011 as shown in Figure 1.
A plurality of raw wood veneers 1 from Liao are laminated with adhesive colored in natural oak color, and this is pressed with a pair of upper and lower flat molds 2 and 3 as shown in Fig. 3. A first flitch 4 as shown in is made. Next, by subjecting this first flitch 4 to straight-grain slicing (slicing in the direction of the arrow), a thin sliced veneer 5 having a thickness of about 0.4 tm as shown in FIG. 4 is produced. Next, a plurality of these thin sliced veneers 5 are laminated with an adhesive colored in natural oak color, and this is pressed with a pair of upper and lower flat molds 2 and 3 as shown in FIG. A second flitch 6 as shown in FIG.
Create. In this case, the veneer 5 is thin and the colored adhesive penetrates into the veneer 5 due to the application of the pressing pressure, so that the entire second flitch 6 appears to be colored in a natural oak color. It becomes colored. Next, this second flitch 6 is sliced to a thickness of 0.8 to 1.5 degrees as shown in FIG. Make Oval slice veneer 7.

This veneer (5) 7 has an oak color (due to penetration of colored adhesive). Next, this sliced veneer 7 is subjected to an uneven process (or scraped with a chisel) using a roll press or the like to form an uneven veneer 8 as shown in FIG. FIG. 9 is an enlarged view of this uneven veneer 8. Next, a plurality of these uneven veneers 8 are laminated with adhesive, and as shown in FIG. 11
A flitch 11 as shown in the figure is made, and then this flitch 11 is sliced parallel to the laminated surface (grain slice,
Slice in the direction of the arrow shown). As a result, the 12th
As shown in the figure, the concave part 8a (Fig. 9) of the uneven veneer 8 appears as a conduit 12 on the surface of the veneer, and the conduit I2 expresses the hole part 13. A decorative veneer 14 is obtained. Reference numeral 15 denotes a non-perforated portion expressed by a portion 8b of the uneven veneer 8 (FIG. 19) other than the uneven portion.

In this way, in this example, the target laminated decorative veneer 14 is obtained without bleaching or dyeing the raw wood veneer 1, but this is because the first flitch 4 has a straight grain (6) slice. To make a thin veneer 5 by applying a colored adhesive to form a second flitch 6, the colored adhesive penetrates into the veneer 5, thereby forming a second flitch 6.
This is based on the fact that since the entire wood veneer 1 appears to be colored in natural oak color, it is not necessary to bleach or dye the raw wood veneer 1 to color it in natural oak color. In this way, the thin veneer 5 is sufficiently colored by applying the colored adhesive and pressing it, so the adhesive that adheres the raw wood veneer 1 is not necessarily colored in natural oak color. Good too. The reason why flitching is performed twice is to prevent the wiping agent from penetrating into the non-perforated portions 15 and to provide unevenness when the veneer surface of the obtained laminated decorative veneer 14 is subjected to the wiping treatment. This is done to improve the physical properties (strength) of the veneer 7.

In the above embodiment, a pair of upper and lower curved plates 9.10
The flitch 11 obtained by pressing is sliced parallel to the laminated surface to obtain the grain laminated decorative veneer 14, which is then sliced at right angles to the laminated surface to obtain straight-grained decorative veneer. You can do it like this. (7) Instead of making the flitch 11 using only the uneven veneer 8, the flitch 11 may be made using a combination of this and a normal veneer. Furthermore, the processing applied to the flitch 11 is not limited to the above-mentioned slicing processing, but may also include sawing, planing, glazing, etc. It is not limited to a thin single plate shape, but may be a thick plate shape or a columnar shape.

〔Effect of the invention〕

Since the present invention manufactures laminated timber as described above, it is possible to manufacture laminated timber with high yield.
