JPH0542505A - Formation of annual ring pattern of wooden material for exterior use - Google Patents

Abstract

PURPOSE:To form the same grain as the grain shaven out of one natural wood to a wooden material for exterior use by superposing a plurality of wood veneer cut to have a thickness corresponding to the width of a desired annual ring in the thickness direction, bonding the veneer and manufacturing plywood and cutting and working the plywood in a desired shape. CONSTITUTION:A plurality of wood veneer 11 are cut in thickness corresponding to the width of a desired annual ring. These wood veneer 11 are superposed in the thickness direction, and bonded with colored adhesives 13, thus forming plywood (a laminated material), in which a plurality of colored adhesive 13 layers are shaped among wood veneer 11. The plywood is cut and worked in a desired shape, thus obtaining a wooden material for exterior use having a three-dimensional design having the desired shape and a desired annual ring pattern.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming an annual ring pattern on a wooden exterior material. A wood veneer is pasted with a colored adhesive and cut to form a large wood product such as a piano or a piece of natural wood. It forms a wood grain pattern similar to that carved from.

[0002]

2. Description of the Related Art It is extremely difficult to machine a large exterior material such as a bending side plate of a grand piano from a solid material. Therefore, conventionally, a wood grain piano exterior material (bending side plate) is formed by superimposing a decorative plate having a thickness of about 3 mm on the surface thereof and simultaneously adhering the same to the core. The outer peripheral shape of the side plate molded in this manner is formed in the same shape as the bending shape, and the side plate has a planar wood grain pattern due to the decorative plate.

[0003]

However, in such a conventional side plate forming method, the design of the side plate is limited to that performed on a plane, and a three-dimensional design is impossible. was there.

Therefore, an object of the present invention is to provide a method for forming an annual ring pattern on a wooden exterior material that enables a three-dimensional design.

[0005]

According to the present invention, a plurality of wood veneers are cut into a thickness suitable for the width of a desired annual ring, and the wood veneers are superposed in the thickness direction and bonded with a colored adhesive. This is a method for forming annual ring patterns of a wood exterior material, in which a plywood having a plurality of colored adhesive layers between wood veneers is formed, and the plywood is cut into a desired shape.

[0006]

According to the present invention, an arbitrary annual ring pattern can be formed by appropriately selecting the number and thickness of the laminated wood veneers or the color of the adhesive. further,
By cutting the plywood into an arbitrary shape, it is possible to give a three-dimensional design to the desired shape of the exterior material having the desired annual ring pattern.

EXAMPLE A method for forming an annual ring pattern of a wooden exterior material according to the present invention will be described below based on examples. 1 to 4 are views for explaining one embodiment of the present invention.

First, as shown in FIG. 1, a plurality of wood veneers 11 having a predetermined thickness are superposed, and the wood veneers 11 are adhering and laminated with a colored adhesive. To do. For example, as shown in FIG. 2, wood that can be used as a decorative board is processed into a thickness that assumes the grain of wood that appears after finishing, and these are stacked in parallel and laminated to a desired thickness. The laminated material (plywood) 12 is formed into a shape as a side plate of a grand piano. in this case,
The layer of colored adhesive is equivalent to the winter of annual rings of wood,
The wood veneers 11, ... Correspond to the summer of annual rings. Therefore, a dark-colored adhesive is used as this colored adhesive. For example, the color is red, black, dark brown, or the like. A resorcinol-based adhesive is suitable as the colored adhesive. Further, for example, a urea resin adhesive containing a black or dark brown pigment may be used.

Next, as shown in FIGS. 3 and 4, the laminated material (plywood) 12 is carved out based on a desired three-dimensional design. In the side plate 12 as an exterior material produced as a result of this, the laminated wood veneers 11, 11, ... Looks like the equivalent of that winter. That is, a plate material having a light color is used as the wood veneer 11 and a color darker than the color of the wood veneer 11 is used as the adhesive 13 to form the annual ring pattern. Further, it is also possible to form a desired annual ring pattern by laminating the individual wood veneers 11, ... With different thicknesses.

After the shaving process, the surface is coated with, for example, a transparent paint. Also, at this time,
The difference in color between the wood veneers 11, ... Of each layer can be obscured by coloring during coating.

[0011]

According to the present invention, a wooden exterior material having a three-dimensional design having a desired shape and a desired annual ring pattern can be obtained at low cost, as in the case of cutting out from natural wood.
