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, in order to express concentrated conduits found in the pores of natural oak, zelkova, etc., on a laminated decorative veneer, a material veneer for expressing the concentrated conduit and a material veneer for expressing other parts are used. The materials are laminated and bonded as appropriate to form a flitch, and then sliced. The material veneer used to express this concentrated conduit is one obtained by laminating and gluing multiple wood veneers to create a flitch, and then slicing it. The veneer surface of the laminated decorative veneer obtained by using such a material veneer for expressing concentrated conduits and a normal wood veneer is coated with an adhesive layer of the material veneer for expressing concentrated conduits. is expressed. However, in such concentrated conduits, natural oak wood.

It felt a little different from the concentrated conduit made of zelkova wood.

[Purpose of the invention]

The purpose of this invention is to form a natural-looking concentrated conduit.

[Disclosure of the invention]

This invention is a method for producing laminated wood, in which a flitch is created by laminating and bonding a plurality of veneers, and the flitch is processed to obtain a laminated lumber. As a single plate of material for the part, uneven processing is applied by applying pressure.
The feature is that the concave portion is filled with a coloring agent.

In other words, by doing this, it becomes possible to express a concentrated conduit similar to natural oak or zelkova wood.

Next, this invention will be explained in detail based on one example.

First, a veneer for expressing a concentrated conduit is manufactured as follows (in other words, multiple wood veneers are laminated and glued together to create a flitch, and this flitch is sliced (straight grained) to produce the material veneer. Then, the obtained material veneer is subjected to uneven processing using a roll press, a normal press, etc., and the concave portions are filled with a coloring agent using a reverse coater, etc., to create a veneer for expressing a concentrated conduit.Next, , This veneer and a normal wood veneer are appropriately combined and laminated and bonded (~, then the obtained flitch is sliced parallel to the laminated surface (
A laminated decorative veneer is manufactured by cutting the grain (board graining). As shown in Fig. 1, on the veneer surface of this laminated decorative veneer, a concentrated conduit portion l is expressed using a veneer for expressing a concentrated conduit, and a portion other than the concentrated conduit portion 2 is expressed using a normal wood veneer. .

In this concentrated conduit section l, a colored part 3 formed by the four colored parts of the veneer for expressing a concentrated conduit, and an adhesive layer part 4 of the veneer for expressing a concentrated conduit appear. It looks very similar to a concentrated conduit of wood.

Note that instead of the veneer for expressing a concentrated conduit described in -, a veneer for expressing a concentrated conduit manufactured as follows may be used. In other words, a unit for expressing a concentrated conduit is obtained by applying unevenness to a normal wood veneer by applying roll compression, plate compression, etc., and then filling the four parts with a coloring agent using a reverse coater or the like. A board may also be used.

By appropriately combining the veneer for expressing a concentrated conduit obtained in this way and a normal wood veneer to create a flitch, and slicing this, a laminated decorative structure with a veneer surface as shown in Figure 2 is created. A veneer is obtained. The concentrated conduit portion 1 of this laminated decorative veneer has a colored portion 8 made up of the four colored parts of the veneer for concentrating conduit representation, giving it an extremely natural appearance.

2 is the part other than the central conduit section made of ordinary wood veneer.

In the above explanation, the slice processing is applied to the flitch (5), which is made using a veneer for expressing a concentrated conduit and a normal wood veneer, but the processing applied to the flitch is It is not limited to slicing processing.

For example, planing, sawing, etc. may be applied to obtain laminated wood or columnar laminated wood that is thicker than laminated decorative veneer.

Next, examples will be described.

[Example 1] Labra's 0. η7 thickness veneers were laminated and bonded using brown vinyl acetate adhesive to form a flitch, and then 0
．． Slice into 7n thick pieces to obtain a veneer of material.

This material veneer was processed to have concave and convex features using a roll press, and a reverse coater was used to fill the concave portions with a brown coloring agent to create a veneer for expressing a concentrated conduit.

On the other hand, Parosapis 1. (L, / Table veneer was dyed in the color of zelkova using acid dye.Next, the veneer for expressing the concentrated conduit and this zelkova colored veneer were combined and laminated with vinyl acetate adhesive. This is then pressed into a flitch using a pair of upper and lower mold plates with curved mold surfaces (6), and the resulting flitch is sliced parallel to the laminated surface to a thickness of 0.4 nm. A laminated decorative veneer was obtained. On the veneer surface of the obtained laminated decorative veneer, the concentrated conduit section by the veneer for expressing concentrated conduit was expressed in a state that closely resembled the concentrated conduit section of natural zelkova. .

[Example 2] A 0.8-thickness veneer of Doubles Fumar is processed with unevenness using a roll press, and a brown coloring agent (mainly vinyl acetate resin) is applied to the depressions using a reverse coater to create a concentrated conduit. I made a veneer for this purpose.

On the other hand, a 1.0 mm thick veneer of Bell Book was dyed a zelkova color using an acid dye. Next, the above-mentioned veneer for expressing a concentrated conduit and the dyed veneer are laminated together using vinyl acetate adhesive, and this is pressed using a pair of upper and lower mold plates with curved mold surfaces. The material was flitched and sliced parallel to the laminated surface into 3 mm thick pieces to obtain laminated decorative veneers. Similar to Example 1, this laminated decorative veneer expressed a concentrated conduit portion that closely resembled the concentrated conduit portion of natural zelkova wood.

〔Effect of the invention〕

In order to manufacture laminated wood in the manner described above, the present invention can express a concentrated conduit in the laminated wood that closely resembles the concentrated conduit of natural oak and zelkova wood.
