Description

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

Conventionally, in order to obtain artificial decorative veneers with teak patterns on the wood surface, multiple veneers dyed in multiple colors were appropriately combined, laminated on a flat surface using adhesive, and then pressed together. Glue to obtain a composite fritsch,
Since this composite fritchi was sliced in the direction that intersects the laminated surface, ultra-thin veneer material (0.1 to 0.3 mm thick) was incorporated in some parts to express the thin stripes seen in natural teak patterns. Not only is the process cumbersome, but the discontinuity of the stripes that is naturally seen in the resulting teak pattern cannot be reproduced, resulting in a lack of natural feel.

Therefore, an object of the present invention is to provide a method for manufacturing an artificial decorative veneer that can reproduce a natural-looking teak pattern.

An outline of this invention is shown in FIGS. 1A to 1G.

That is, in this method of manufacturing artificial decorative veneers, a plurality of material veneers 1 and 1' made of lauan wood, agathis wood, etc. that have been dyed in a plurality of colors are glued together as shown in FIG. 1A. A primary assembly frit 3 is laminated in an appropriate combination through a flat mold 2 having a gently uneven pressing surface with a level difference of about 1 to 5 mm, and is pressed and bonded as shown in FIG. This primary assembled fritsch 3 is sliced almost parallel to the laminated surface with a slice thickness smaller than the thickness of each material veneer 1, 1' as shown in Figure C, and then sliced as shown in Figure D. different material veneer layer 1
A sliced veneer 4 in which a, 1'a are combined in a laminated manner...
... are obtained, and these plurality of sliced veneers 4... are combined with the material veneers 1 and 1' and laminated as shown in Fig. E through adhesive, and then pressed and bonded as shown in Fig. F. (In this example, a flat type 2' is used) to obtain a secondary assembled flitch 5, and this secondary assembled flitch 5 is sliced at a predetermined slice angle intersecting the laminated surface as shown in Fig. G. Thus, an artificial decorative veneer 6 as shown in FIG. 2 is obtained.

The appropriate thickness of the raw material veneers 1, 1' is 0.8 to 1.2 mm, and the thickness of the primary slice is approximately 0.6 mm relative to the thickness of the raw material veneers 1, 1'.

In addition, as shown in FIG. 1G, in an example in which a straight-grain patterned artificial decorative veneer 6 is obtained by slicing the flat-pressed secondary assembly fritsch 5, a slicing angle of 15 degrees (width direction ) is suitable for slicing to a thickness of 0.2 mm.

In this way, the primary laminated flat 3 is sliced almost parallel to the laminated surface with a slice thickness thinner than the thickness of the material veneers 1, 1' to obtain the sliced veneers 4... Plate layers 1a, 1'a
The sliced veneer 4 obtained in this manner can be partially combined with the material veneers 1 and 1' to slice the secondary assembled fritsch 5 obtained. According to the third
As shown in the figure, an extremely thin material veneer layer 1a formed on the sliced veneer 4 by the above-mentioned primary slicing,
1'a appears as a thin striped pattern on the surface of the artificial decorative veneer 6, making it possible to reproduce a striped pattern that closely resembles a natural teak pattern.

In addition, since the primary assembled fritsch 3 is pressed and formed with a flat mold 2 having a gently uneven pressing surface with a step difference of about 1 to 5 mm, the primary slicing process is performed as shown in Fig. 2. The width of each raw material veneer layer 1a, 1'a appearing on the material surface of the obtained sliced veneer 4 has a gradual change, and this raw material veneer layer 1
By changing the widths of a and 1'a, a sense of discontinuity is expressed in the striped pattern on the surface of the artificial decorative veneer 6 finally obtained, and the striped pattern can be made to more closely resemble a natural teak pattern.

Furthermore, since the process of fritchi molding and slicing is repeated twice to reproduce such a cheek pattern, the degree of compositeness of the material veneers 1 and 1' that make up the artificial decorative veneer 6 increases, and its strength increases. can be significantly improved.

Although the above explanation describes an example of obtaining an artificial decorative veneer that reproduces a straight-grained teak pattern, it is also possible to obtain a wood-grained veneer by molding the secondary laminated fritchi into a textured shape. It can be reproduced in almost the same way.

Specific example conditions of one embodiment of this invention will be described below.

Material veneer: 1.0mm thick Wawa wood dyeing Color: 2 types of dyeing B and light yellow Y Lamination combination of primary lamination fritchi: B and Y repetition Primary slice angle: Parallel to the lamination plane Primary slice thickness: 0.5mm secondary laminated fritsch combination:
Repeating CCYYCYYYCY (where C is sliced veneer) Secondary slice angle: 90 degrees to the laminated surface A teak pattern close to natural was reproduced on the surface of the artificial decorative veneer thus obtained.

Specific example conditions of other embodiments of this invention will be described below.

Material veneer: 1.0mm thick amberoy wood dyed Color: 2 types of brownish B and light yellow Y Laminated combination of primary laminated fritchi: BBYBYBY repetition Primary slice angle: 0.5 from the longitudinal direction to the laminated surface
Degree 1st slice thickness: 0.8mm Lamination combination of 2nd assembly Fritsch:
Repeating CCYCYYYCY (C is sliced veneer) Secondary slice angle: 35 degrees to the laminated surface The artificial decorative veneer thus obtained reproduced a teak pattern with a sense of discontinuity on its surface. .

As described above, the method for producing artificially decorated veneers of the present invention uses a plurality of material veneers dyed in a plurality of colors to form a gently uneven pressing surface with a level difference of 1 to 5 mm using an adhesive. a primary assembly fritch forming step in which a primary assembly frit is obtained by laminating and press-bonding the first assembly fritches into a flat mold, and slicing the primary assembly fritches substantially parallel to the laminated surface with a slice thickness smaller than the thickness of the material veneer. a primary slicing step to obtain a sliced veneer; a secondary assembled fritch forming step in which the sliced veneers are laminated and pressure-bonded via an adhesive to obtain a secondary assembled frit; Since this process includes a secondary slicing process in which the slicing is performed in a direction that intersects the laminated surface, it is possible to reproduce a wood grain pattern that closely resembles a natural teak pattern with thin stripes and a sense of discontinuity in the resulting artificial decorative veneer material. It has the effect of being able to.
