Description

[Detailed description of the invention] 〔Technical field〕 This invention relates to a method for manufacturing decorative laminated veneers.

[Background technology 1] In general, in order to give a post made of a low-grade material a wood texture similar to that of a high-grade natural post as shown in Figure 1, a wood grain pattern on the surface of a high-grade post is used. It is possible to make a decorative veneer with a part where it appears and a part corresponding to the part where the straight-grained wood pattern appears on the side, and then attach it to the outer peripheral surface of a low-grade pillar material to form a pillar-shaped laminated timber. It is being done.

That is, when a natural decorative veneer is manufactured by slicing natural wood having a portion corresponding to the part where the grain pattern 2 of the high-quality pillar material 1 shown in FIG. A natural decorative veneer is created by slicing the natural wood with the part corresponding to the area where the straight grain pattern 3 appears, and these two veneers are horizontally spliced to make one wide decorative veneer, and this is made into a low-grade decorative veneer. Figure 2 shows a wide decorative veneer made by horizontally joining two types of natural decorative veneers.In Figure 2, 4 indicates straight grain. 5 is a natural decorative veneer part with a pattern, and 5 is a natural decorative veneer part with a grain pattern. However, two types of natural decorative veneers obtained by slicing natural wood are horizontally spliced to form 2N1. When obtaining a wide decorative veneer 6 as shown, a natural decorative veneer section 4 having a straight grain pattern 3 and a natural decorative veneer section 5 having a grain pattern 2 are used.
It is extremely difficult to make the grains of both sides continuous at the cross-joint part A, and the wood grains often become discontinuous at the cross-joint part A. Therefore, the columnar laminated wood made of the wide decorative veneer 6 in which the wood grain is discontinuous in the middle has a slightly unnatural feel compared to the natural column material.

[Purpose of the invention]

The present invention was made in view of the above circumstances, and an object of the present invention is to provide a method for manufacturing a laminated decorative veneer that can be used for manufacturing laminated lumber with a natural wood texture.

[Disclosure of the invention]

This invention consists of a first 7-rich piece made by placing a plurality of wood veneers into a pair of upper and lower molds with curved mold surfaces, laminating and bonding them and processing them into a columnar shape, and the wood grain that appears on one side of this flitch. A second flitch is prepared that matches the grain or edges of the wood that appears on one side of the flitch, and the first flitch and the second flitch are aligned with the ends of the wood grain on each side. The gist of this invention is a method for producing a laminated decorative veneer, which is characterized in that a laminated decorative veneer is obtained by gluing the third flitch to form a third flitch, and slicing this third flitch parallel to its - face. It is something to do.

That is, in the laminated decorative veneer obtained by this manufacturing method, the wood grain is continuous at the joint between a part where a certain wood grain pattern appears and a part where another wood grain pattern appears. Therefore, when columnar laminated wood is manufactured using this, it is possible to obtain columnar laminated wood that has a woody texture with a rich natural feel.

Next 1. This invention will be explained based on examples.

First, a plurality of wood veneers are placed in a pair of upper and lower molds with curved mold surfaces, laminated and bonded together, and the resulting laminate is processed into a columnar shape to create a first flitch.

Next, a plurality of wooden veneers are cut into a mold with a curved surface so that the wood grain appearing on one side of this first seven-rich piece matches the wood grain appearing on one side of the first 7-rich wood at each end. A second flitch is made by laminating and bonding using a pair of molds and processing into a columnar shape. In this case, the first 7 rich and the second
Forming the grains of the 7-rich pieces so that they match at their ends requires adjusting and using the molds used to make the first 7-rich pieces and the molds used to make the second 7-rich pieces. This can be easily done by adjusting the thickness of the wood veneer.

Next, the first 7 rich obtained in this way and the second
A third 7-rich piece is obtained by cross-joining each of the 7 rich pieces using adhesive with the wood grain edges aligned. The third 7-rich 7 thus obtained is shown in FIG. In FIG. 3, 8 is the first 7-rich portion and 9 is the second 7-rich portion.

In the first flitch portion 8, a plank pattern appears, and in the second flitch portion 9, a straight grain pattern appears. Next, the thus obtained third flitch 7 is sliced parallel to its negative surface (as indicated by arrow A in the figure) to obtain a laminated decorative veneer. In the laminated decorative veneer thus obtained, a grain pattern portion formed by the first seven rich portions 8 and a straight grain pattern portion formed by the second flitch portion 9 appear. Next, as shown in FIG. 4, the laminated decorative veneer thus obtained is folded from the boundary between the grain pattern portion 10 and the straight grain pattern portion 11 to form the outer peripheral surface of a low-grade columnar material 12. Paste. As a result, as shown in FIG. 5, the upper surface 13 and one side surface 14 of the low-grade columnar material 12 are covered with a laminated decorative veneer having a continuous wood grain pattern. In the same way, by covering the other side and bottom surface of the low-grade columnar material 12 with a laminated decorative veneer with a continuous wood grain pattern similar to the above, a columnar laminated material with a wood texture similar to that of natural products can be obtained. be able to obtain it.

FIG. 6 is an explanatory diagram of another embodiment of the present invention.

That is, in this embodiment, a flitch 15 obtained by placing several pieces of wood veneer into a pair of upper and lower molds with curved mold surfaces, laminating and bonding them and processing them into a columnar shape is formed from the dotted line part in the figure. The cut portion 15a is then glued to the remaining flitch portion 15b with the end surface 16 facing upward as shown in FIG. Then, the obtained adhesive body 15 is sliced parallel to its surface to obtain a laminated decorative veneer in which a portion with a wavy wood grain pattern 17 and a portion with a chevron wood grain pattern 18 appear.

Next, this laminated decorative veneer 19 is bonded in a bent state to a low-grade columnar material 20 as shown in FIG. As a result, as shown in FIG. 9, a wavy wood grain pattern 17 is imparted to the end surface of the low grade columnar material 20, and a medium wood grain pattern 18 is imparted to the butt surface.
will now be granted.

In this case, since the grain of the wood is continuous between the end surface and the upper surface, a wood texture with a natural feel can be obtained.

〔Effect of the invention〕

As described above, the present invention provides a first 7-rich piece made by placing a plurality of wood veneers into a pair of molds with curved mold surfaces, laminating and bonding them and pressing them into a columnar shape, and this flitch. A second flitch is semi-jiffed such that the grain appearing on one side of the flitch meets the grain appearing on its own side at its ends.
L/, the first flitch and the second 7 flitch are glued together with the grain edges of each side aligned, and the third flitch is made.
By slicing this third flitch parallel to its − plane, a laminated decorative veneer is made:
Therefore, it is possible to obtain a laminated decorative veneer in which the wood grain on the negative side and the wood grain on the other side are continuous, and it is possible to produce a laminated lumber with a natural wood texture.
