Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for manufacturing a decorative veneer, and more particularly to a method for manufacturing a decorative veneer expressing a parquet-like wood grain pattern.

[Background technology]

A composite flitch is obtained by laminating, pressing, and gluing multiple veneers, which are then sliced from a predetermined direction to create a wood grain pattern consisting of numerous growth rings on the surface of the board.Resembling the wood grain pattern of natural wood species. It was used to express wood grain patterns, straight grain patterns, etc.

[Purpose of the invention]

An object of the present invention is to provide a method for manufacturing decorative veneers that can easily produce parquet-like decorative veneers in various patterns.

[Disclosure of the invention]

The decorative veneer manufacturing method of the present invention includes the steps of laminating a plurality of material veneers via an adhesive and press-bonding them to obtain a primary flitch; A step of obtaining two types of sliced plates whose stacking directions are orthogonal to each other by slicing them from parallel directions, and a step of laminating the two types of slices and plates alternately with an adhesive and bonding them by pressure to form a secondary flitch. a step of slicing the secondary flitch from a direction perpendicular to the bonding surface, and forming a plate-like body in which blocks in which the lamination direction is vertical and blocks in which the lamination direction is horizontal are alternately repeated along the longitudinal direction of the end face; The method includes the steps of obtaining a tertiary flitch by alternately shifting a plurality of the plate-shaped bodies one block at a time, stacking them with an adhesive and bonding them by pressure, and slicing this.

This will be explained below with reference to FIGS. 1 (4) to (6). A plurality of rotary or sliced veneers 1, dyed and dried as required, are laminated on a flat surface using an adhesive and bonded by pressure to obtain a primary flitch 2 (Fig. 1 (g) and
)). Next, this primary flitch 2 is sliced into appropriate thicknesses in a direction perpendicular to and parallel to the stacking direction, respectively, to form a first slice plate 3 having the same dimensions and the same thickness.
and the second slice plate 4 (Fig. 1 (O and (6)
)). The first and second slice plates 3, 4 have their end faces 3
A laminated pattern perpendicular to each other is formed on a and 4a,
This laminated pattern is natural, i! It corresponds to the grain of the υ species.

Thereafter, the first and second slice plates 3.4 are alternately stacked on a flat mold and pressed together in the same manner as above.

A secondary flitch 5 is obtained by adhering (FIG. 1(g)). By slicing this secondary flitch into an appropriate thickness from a direction perpendicular to its adhesive surface, a plate-like body 6 as shown in FIG. 1 is obtained. This plate-like body 6 has a plurality of blocks 7, 8 connected to its end face along the longitudinal direction, the lamination direction (wood grain) repeating alternately vertically and horizontally. The size of each block 7.8 can be determined by appropriately selecting the slice width of the primary flitch 2 and the secondary flitch 5.
It is preferable that the slice width of the next flitch 2.5 is the same so that each block is square.

As shown in FIG. 1(G), the plate-shaped body 6 is made by stacking a plurality of plates by alternately shifting each block 7.8 and pressing them together.
A tertiary flitch 9 is obtained by gluing. Next, by slicing this tertiary flitch from a direction perpendicular to the adhesive surface, a decorative veneer 10 with a parquet-like wood grain pattern expressed on the board surface is obtained.
can be obtained.

Various patterns of parquet-like decorative veneers can be obtained by combining the slice widths of the above-described secondary and secondary flitches 2.5 and the combination of veneers 1 made of various materials. Furthermore, the first and second slice plates 3.4 do not necessarily need to be obtained from the same primary flitch 2, but the first and second slice plates 3.4 are obtained from various primary flitches having different colors and materials. A slice plate 3.4 can be obtained.Next, the present invention will be explained by giving examples.
:Agathis 1. A plurality of thick veneers were dyed dark brown and pale yellow at a ratio of 1=1, and tertiary flitches were obtained as shown in Figure 1.

When this flitch was sliced, a parquet-like decorative board consisting of a combination of 30 x 30 blocks was obtained.

Example 2: Certeis and Ius each 1.0m+n
A decorative veneer with a textured marquetry style was obtained by combining blocks of 50 x 50 mm in the same manner as in Example 1, except that multiple thick veneers were used as raw material veneers without being dyed. Ta-1 [Effects of the Invention] According to the present invention, it is possible to easily obtain parquet-like decorative veneers with various patterns depending on the slice width of the primary and secondary flitches and the combination of material veneers or sliced boards. It has the effect of being able to

Claims (1)
