Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a decorative veneer and a decorative plywood as building and furniture materials, in which an inlaid pattern is applied to a thin veneer made of wood shaped like laminated wood.

(Conventional technology) Conventionally, the inlaying technology for this type of decorative plywood involves cutting (slicing) thin veneers (natural veneer) of various types of wood onto the board by hand in a pattern pattern one by one. The pattern is formed into a pattern, and the pasting process is all done by hand and requires highly skilled techniques, so the processing work is extremely complicated, results in large losses, and is low in efficiency. Therefore, as building materials and furniture materials, they are expensive, leading to high costs, and are therefore limited to high-end products.

(Problems to be Solved by the Invention) This invention relates to the formation of parquet-style thin veneers and plywood for building and furniture materials that are fully decorated with inlaid patterns. By cutting (slicing) them orthogonally, a parquet-style decorative veneer and plywood with an inlaid pattern are constructed, which can be mass-produced mechanically.

(Means for solving the problem) For this purpose, a laminate formed by laminating and bonding a plurality of flitch materials made of wood with an adhesive has a cavity of an arbitrary cross-sectional shape in the direction parallel to the joint. A plurality of flitch materials made of wood are bonded to an inlaid decorative veneer, which is characterized by forming and filling a patterned material, and cutting this filled laminate in a direction perpendicular to the patterned material. A process of joining the laminated body with a laminated agent to form a laminated body, a process of forming a cavity having an arbitrary cross-sectional shape in the laminated body in a direction parallel to the joint part, and inserting and filling the patterned material into the laminated body, and this filling lamination process. It is formed by cutting the body in a direction perpendicular to the pattern material.

In addition, in a laminate formed by laminating and bonding multiple flitch materials made of wood with adhesive, a cavity of an arbitrary cross-sectional shape is formed in a direction parallel to the joint, and a patterned material is inserted and filled. The inlaid decorative plywood is characterized in that a thin veneer obtained by cutting a laminate in a direction perpendicular to the pattern material is adhered to a substrate via an adhesive, and a plurality of flitches made of wood are attached using an adhesive. forming a cavity having an arbitrary cross-sectional shape in the direction parallel to the joint part and inserting and filling the pattern material into the cavity, and forming the filled laminate into a pattern. It is formed by going through the steps of cutting in a direction perpendicular to the material to form a thin veneer, and pasting this thin veneer to a substrate with an adhesive.

(Function) - A patterned material in which a cavity with an arbitrary cross-sectional shape is formed in a direction parallel to the joint in a laminate made by laminating multiple fributi materials and bonded with adhesive, and the pattern material is inserted and bonded into this cavity. By sequentially cutting the laminate in a direction orthogonal to the laminate, it is possible to reliably and efficiently mass-produce uniform decorative veneers in which patterns of arbitrary shapes are inlaid into thin veneers with marquetry-like striped patterns. At the same time, since the pattern material with a relatively small cross section is cut as a whole while being surrounded and bonded by the cavity of the laminate, the pattern material can be cut into a single thin veneer without cracking or chipping around the pattern material during cutting.
: Can be deleted. However, in inlaid decorative veneer
The patterned portion is tightly fitted and supported on the side of the cavity wall, without creating any gaps, and there is no fear that it will easily fall off or separate.

Furthermore, these effects make it easier to adhere the parquet-style inlaid veneer to the substrate with adhesive, and ensure the efficient and uniform production of parquet-style decorative plywood with tightly fitted inlays. In addition, together with the adhesion of the patterned portion to the substrate surface, the patterned portion is tightly fitted and adhered to other parquet portions and is not easily peeled off.

(Example) Specific embodiments of the invention will be described with reference to the drawings.

In the figure, (1) is a laminate, such as Sugi, Hinoki, Nara, Beech, etc.
It is formed by laminating a plurality of flitch materials (2) formed by cutting teak, rosewood, or any other wood into long square pieces along the grain of the wood and bonding them together with an adhesive (3). This laminate (1) may have any cross-sectional shape, such as a triangular cavity (
4) Form all arbitrary numbers of through holes. Similarly, cut a piece of wood along the grain of the wood with a pattern having the same cross section as the cavity (4), that is, a triangular cross section (
5), apply an adhesive (6) to the outer periphery of the adhesive (6), insert and fill the cavities (4) of the laminate (1), and connect them. An even stronger bond can be obtained. In addition, a dry pattern material (5) is inserted and bonded to a laminate (1) with a high moisture content, and the pattern material (5) absorbs water and expands to form a strong fit into the cavity (4) without using an adhesive. They can also be combined. Note that the cavity (4) does not need to be provided by penetrating the laminate (1) as shown in the figure, but can be formed by cutting (
It is also possible to use a unidirectional cave that is bored halfway along the edge that corresponds to the gripping and fixing part of the laminate (1) in the slicing process.

This filled laminate (1) is sequentially cut (sliced) with a knife 00 to a thickness of 02 to 0.6 nm in a direction perpendicular to the pattern material (5) to form a thin veneer (7). This thin veneer (7) is provided in a wet state or a dry state depending on its use, and may be lined with Japanese paper, cloth, etc.

In this cutting (slicing) process, the flitch material (2) and the patterned material (5) are cut in a dry state or in a moderate moisture content state depending on the wood quality, and generally a certain moisture content makes the wood soft and easy to cut. It is said to be advantageous in that it provides a beautiful front surface. Therefore, depending on the quality of the wood, when the flitch material dries, when slicing it into thin veneers, the fiber structure splits and breaks apart due to the drying, making it impossible to slice into plates. For this reason, by soaking the wood in water to make it hydrated or boiling it to increase the moisture content, the water content is softened and made easier to cut. This is a widely used technology and is a publicly known technology that has existed since the birth of natural veneer (thin veneer).

Next, the parquet-like thin veneer (7) with the inlaid pattern (5a) formed by cutting is applied to the surface of the substrate (8) made of wood or other arbitrary material with adhesive (9), and the mixture is heated. By pressing and adhering, an inlaid decorative plywood is formed.

By forming the pattern material (5) with wood and inserting and joining it with the laminate (1) so that the wood grains are perpendicular to each other, the wood grain skin that appears on the cut surface of the parquet style thin veneer (7) The contrasting combination of annual rings makes the inlaid pattern (5a) stand out vividly and can express a unique pattern.

(Effect of the invention) As mentioned above, this invention is a laminate made of wood:'? :.

A cavity is formed in the direction parallel to the joining part, a pattern material is inserted and filled into this cavity, and the joint is bonded.This bonded laminate is sequentially cut in a direction perpendicular to the pattern material to create a marquetry-style inlaid decorative veneer. It is characterized by forming this with plywood pasted,
A decorative veneer with a marquetry style that can be created with a uniform inlay pattern by arbitrarily changing the cross-sectional shape of the cavity of the laminate and the pattern material into a liquid phase, and then going through a mechanical cutting process. (Natural veneer) and plywood can be produced easily and reliably by machine.

Therefore, by mechanically mass-producing decorative veneers and plywood in a marquetry style with inlaid patterns, costs can be reduced by mechanically mass-producing decorative veneers and plywood with an inlaid pattern. There are effects that can be provided.

In addition, the patterned portion of the inlaid thin veneer formed by cutting is firmly fitted and held by the cavity wall of the veneer portion, so that the integral plate can be maintained without the risk of it coming off easily.
This makes the adhesion process to the substrate easier and more reliable, and together with the adhesion to the substrate, even stronger integrity is obtained and the inlaid decorative plywood can be used for a long time.
