Description

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

Conventional artificial decorative veneer in which material veneers are laminated with an adhesive and bonded by pressure to obtain a flitch, and this laminated flitch is sliced to create a wood grain pattern imitating a natural wood grain layer on the wood surface. In the manufacturing method of , the concentrated conduit part (pore area) as seen in natural zelkova wood, elm wood, etc. is expressed in the wood grain pattern, and the concentrated conduit part is expressed by printing etc. on the surface of the material veneer. Other methods were used, such as stacking sliced veneers sliced in a straight-grained pattern with regular veneers to express the entire concentrated base section.

However, since the concentrated conduits expressed by these methods are uniform, it is not possible to fully express the uneven concentrated conduits found in natural wood, and the grain cannot be said to be close to that of natural wood. .

Therefore, an object of the present invention is to provide a method for manufacturing a decorative veneer that can freely express a concentrated conduit portion to resemble natural wood such as zelkova wood.

A first embodiment of the present invention will be described based on FIGS. 1 to 3. That is, as shown in FIG. 1 (5) to F), this decorative veneer manufacturing method involves arbitrarily combining the veneer 1 for expressing the spring wood portion and the veneer 2 for expressing the central conduit portion. A composite sliced veneer 4 having a straight-grain pattern is obtained by slicing the primary laminated 7-rich 3 obtained by laminating and press-bonding using an adhesive in a flat type (not shown) along the laminated surface and in the direction of direct firing. (Image 2, CB)), the composite sliced veneer 4 is arbitrarily combined with the veneer 1 for expressing the spring material part, laminated, and pressed and bonded with an adhesive using a concave-convex mold 5. The process of obtaining the secondary assembled flitch 6 ((C) and (D) in the same figure) and this 2
The next step is to slice the assembled flitch 6 in a direction intersecting the laminated plane to obtain a decorative veneer 7 having a concentrated conduit portion (see FIG.
(G)) and (F)).

The veneer 1 for expressing the spring material portion and the veneer 2 for expressing the concentrated conduit portion
are dyed veneers for the spring wood part such as zelkova wood and for the central conduit part, respectively, and agathis veneer (about 0.6 to 0.8 m thick) is used for the spring wood part, and For the central conduit section, a single Lapla plate (about 0.8 to 1 m thick) can be used.

In order to obtain the composite sliced veneer 4 using these veneers 1 and 2, the ratio of (veneer 1 for spring material) = (veneer 2 for expressing the concentrated conduit section) is approximately 5 = 2. It is preferable to arbitrarily combine these in order to obtain a concentrated conduit portion that resembles natural materials. FIG. 2 shows the entire end face of the composite sliced veneer 4 with a straight-grain pattern obtained by combining in this manner. This slice veneer 4
As shown in Fig. 3, the secondary assembled flitch 6 obtained by combining the material veneer 1 for spring lumber with lamination and pressure bonding has the concentrated conduit expression part 8 partially missing, and the final product is The uneven and partially missing concentrated conduit portions are expressed in the decorative veneer 7, giving it an extremely natural look.

A second embodiment of the invention will be described based on FIG. 4.

That is, as shown in Figures 4 (5) to (C), the method for manufacturing this decorative veneer is to create a flitch in which a large number of veneers for expressing the concentrated conduit portion are laminated and bonded together by pressure using an adhesive, as described in the above-mentioned embodiment. The sliced veneer 9 obtained by slicing in the same manner as above was cut into appropriate widths along the fiber direction. The sliced veneers 9' cut as shown in FIG. By pressing and bonding, the concentrated conduit representation part 8' as shown in FIG. 4(C) is partially formed (5
) to obtain the missing assembly flitch 6.

In this way, uneven and partially missing central conduit portions can be created in the final decorative veneer obtained by slicing the flitch assembly 6'.

The sliced veneer 9 is sliced to a thickness of about 0.2 to 0.3 w, and is cut to an arbitrary width within a range of about 50 to 100 g. The cuts may be parallel to the fiber direction, or they may be cut diagonally with some inclination. Therefore, even defective veneers (cuts, blurred edges, etc.) that occur when slicing the sliced veneer 9 can be used, and the yield can be improved. In order to obtain a wood grain pattern closer to that of natural wood, it is preferable to appropriately change the cutting width and spacing of the sliced veneers 9 when arranging them. The rest is the same as the first embodiment.

A third embodiment of the invention will be described based on FIG.

That is, in this method of manufacturing a decorative veneer, as shown in FIG. is glued onto the veneer 1' for expressing the spring material part to form a composite veneer 11, and this composite veneer 11 is laminated in combination with the veneer 1' for the narrow spring material part, and bonded by pressure using an adhesive. Then, a flitch assembly 6' as shown in Figure #I5 is obtained, and this flitch assembly 6' is sliced to obtain a decorative veneer 7' having a concentrated conduit portion 12 as shown in Figure (Q). be.

The sliced veneer 10 of the above type has a thickness of about 0.1 to 0.4 ar and is colored by printing or dyeing as required.

In this way, the button, concentrated conduit part 12' is made of bamboo sliced veneer 10
Since the concentrated conduit portion 12 is expressed using , it is possible to express a wood grain pattern that is very dense, has a hard texture, and has a glossy appearance. The rest is the same as the first embodiment.

A fourth embodiment of the invention is shown in FIG. This will be explained based on FIG. That is, in this method of manufacturing a decorative veneer, as shown in FIG. 6 to FIG. A linear pattern is completely formed on the surface of the veneer 13.
The concentrated conduit part 15 and the spring wood part 16 are dyed in the color of spring wood.
It is expressed between two veneers 13, and the veneers 13 are laminated and bonded by pressure to obtain a 7-rich assembly, which is then sliced to obtain a decorative veneer 7'' as shown in Fig. 8. ◎The above bar material 1
5 can be a continuous, discontinuous bar made of stainless steel, polypropylene, etc., which has an outer diameter of 1. They are arranged at predetermined intervals of about 100 degrees.

In addition, examples of dark coloring liquids include PM Yellow 5.0% as Zelkova color and Suminol Milling Brown 3 G (Suminol Milling B
Rown 3 G) 8.0% staining solution was used, and PM Yellow 0.5 was used as the coloring solution for the spring wood color.
A staining solution consisting of % and Suminol Milling φ Brown 3G0.8 is used.

Further, instead of the linear pattern, a mesh pattern (not shown) may be formed on the veneer using a woven fabric, a nonwoven fabric, a mesh sheet, or the like.

In this way, it is possible to express the concentrated conduit portion 15 with an uneven feel based on the linear or mesh pattern on the decorative veneer.

As described above, the method for manufacturing a decorative veneer of the present invention is to combine a veneer for expressing a spring material part and a veneer for expressing a concentrated conduit part, laminate them with an adhesive, and bond them by pressure to form an assembled flitch. Moreover, by slicing this assembled flitch, it is possible to obtain a decorative veneer in which the concentrated conduit portion can be freely expressed to resemble natural wood such as zelkova wood.

Other ways to represent the central conduit section are described below. In other words, as mentioned above, the concentrated conduit part and the spring wood part are dyed separately in ten different colors to express the concentrated conduit tS, but this increases the number of steps and reduces cost and yield. was difficult.

Therefore, as shown in FIG. 9, a transfer sheet 1 is printed on a dust removal sheet 17 with an ink layer 18i representing a concentrated conduit portion in an uneven shape.
9, transfer and press the transfer sheet 19 onto the veneer 2o for expressing the spring material part via adhesive as shown in FIG. After that, the flitch 21 is laminated and bonded by pressure using a concave-convex mold to form a flitch (9) as shown in FIG. Central conduit section 2
The decorative veneer 23 expressing 2 can be easily manufactured.

According to yet another method, when a veneer is manufactured by rotary slicing, a back crack is generated in the veneer, and the back cracked veneer is used to express the entire wood grain pattern having concentrated conduit portions. That is, the cracked veneers are laminated so that the back cracked surface of the veneer is located on the convex side of the uneven mold, and bonded by pressure to obtain an assembled flitch, which is then sliced to produce a decorative veneer.

The back cracks can be formed into a desired number and depth by appropriately adjusting the position of the cutter 25 and the nose bar 26, the slice thickness, the slice speed, etc. when the veneer 24 is advanced as shown in FIG. , the direction of the wood can be obtained, and the required back cracking condition is determined by the wood grain pattern to be expressed.

In this way, the cracks on the back formed in the single plate 24 create a concentrated guiding W part? In other words, there is no sense of incongruity between the spring wood part and the conduit part in terms of texture, color, etc. (10), and the pattern closely resembles the natural wood grain pattern.
