Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing artificially decorated veneers.

Laminated multiple wood veneers with adhesive,
A method of obtaining frits by pressure bonding using a concave-convex mold, etc., and slicing these frits from a predetermined direction intersecting the laminated surface to obtain an artificial decorative veneer in which the layers of each material veneer are expressed as annual ring layers on the material surface. In the case of
The drawback is that minute cracks found at the edges of wood veneers are enlarged by drying treatment, etc., and the cracks are exposed on the surface of the resulting artificially decorated veneer, resulting in a defective product. was.

Therefore, an object of the present invention is to improve the wood usage yield by using the wood veneer with the above-mentioned cracks repaired, and to provide an artificial decorative veneer that can express a natural material feel. An object of the present invention is to provide a manufacturing method.

An embodiment of the invention is shown in FIGS. 1 to 3. In other words, the method for manufacturing this artificially decorated veneer is as follows:
A plurality of veneers are laminated and pressure-bonded using an uneven mold 2 using an adhesive (Fig. 1A) to form a flitch.
This fritsch 3 is sliced from a predetermined direction (FIG. 2B), and the material veneer 1 is a wooden material veneer 1'a having a crack at the end as shown in FIG. In the section, a small width material piece 1'b processed from a wood veneer of the same type obtained from the same lot is made, the fiber direction of which is perpendicular to the fiber direction of the wood material veneer 1'a having the above-mentioned cracks. They are butted together so that they are symmetrical and sewn together 4 using a sewing machine to form a composite wood veneer 1'.

In addition, in the example shown in Fig. 2, a small area of material piece 1'b is sewn to the end of a wooden material veneer 1'a occupying a large area, but in addition, as shown in Figs. 3A and B, As shown, two wood veneers 1''a, 1''a, both of which have cracks at their ends, may be sewn together with a narrow material piece 1''b sandwiched between them to form a composite material veneer 1''. In this case, as in the previous example, the fiber direction of the material piece 1''b is arranged at right angles to the fiber direction of the two wooden material veneers 1''a, 1''a.

Other specific conditions in this example are as follows.

Wood veneer......Timber type: Labra Thickness: 1mm Small piece of material......Timber type: Labra Thickness: 0.8mm Sewing conditions...4-point zigzag stitch As shown above, wood veneer 1 with cracks. ′
a, 1″ This wooden material veneer 1′a, 1″ is attached to the end of a.
Composite wood material veneers 1', 1" are obtained by butt-sewing small width material pieces 1'b and 1"b such that the fiber direction is perpendicular to the fiber direction of a, and this composite wood material veneer 1' , 1" is used as a laminated material veneer, drying treatment of the material veneer (absolute drying method 40
%), the crack expansion is limited to 2 mm, which significantly reduces the occurrence of defects due to cracks compared to 20 mm in the conventional case.

Moreover, by using such composite wood material veneers 1', 1'', not only can scrap veneers with insufficient dimensions be effectively used, but also artificial decorative veneers 5 can be obtained as shown in FIG. The cut surface C of the narrow material pieces 1'b and 1''b reproduces the "edge" and "fu" based on the radial structure found on the surface of natural wood, giving it a natural feel. It is possible to express a rich texture of the material.

As described above, the method for manufacturing artificial decorative veneers of the present invention involves laminating and laminating multiple material veneers via an adhesive.
This is a method for manufacturing artificially decorated veneer in which the frits are formed by pressure bonding and then sliced from a predetermined direction.The method involves attaching small pieces of wood material to each other at the ends of a wood veneer with cracks at the ends. Since a composite wood material veneer obtained by butt-joining the materials so that the fiber directions intersect is used as the material veneer, it is not only possible to effectively utilize scrap veneers with insufficient dimensions. The resulting artificial decorative veneer can express material textures such as "terri" and "fu" based on the radial structure found in natural wood, making it possible to create an artificial decorative veneer with a rich natural feel. It has the effect of being able to.

Claims (1)

[Claims] 1. In a method for manufacturing artificial decorative veneers in which a plurality of wood veneers are laminated and pressed together using an adhesive to create a frit, and the frit is sliced in a predetermined direction, a wood material veneer with cracks at the edges is used. An artificial decorative veneer characterized in that a composite wood material veneer obtained by butt-joining small width wood material pieces to the ends of the board so that their fiber directions intersect is used as the material veneer. manufacturing method.
