Description

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

A decorative veneer in which multiple sheets of veneer are laminated with an adhesive, pressed and bonded to obtain a composite frit, and this composite frit is sliced in a direction that intersects the laminated surface to reproduce a natural wood grain pattern. In the manufacturing method, colored paper colored in the summer wood color is sandwiched between the veneers of the material in order to represent the summer wood found in coniferous trees such as cedar, pine, and cypress in the wood grain pattern to be reproduced. A well-known method is to use paper to represent summer wood and veneer to represent spring wood.

However, the decorative veneer produced by the conventional manufacturing method has a problem in that it lacks a natural look because the line width of the summer wood portion is constant.

Therefore, an object of the present invention is to vary the line width of the summer wood portion, thereby making it possible to express the summer wood portion resembling a natural wood grain pattern.

A first embodiment of this invention will be described based on FIG. In other words, the method for manufacturing this decorative veneer is as follows:
As shown in Fig. 1 a to e, fibrous sheets 1 colored in summer wood color and spring wood material veneers 2 are alternately laminated with an adhesive (Fig. 1 a and b), and then The fritches 4 are obtained by pressing and bonding with a concave-convex die 3 (FIG. 3c), and this is sliced to obtain a decorative veneer 6 on which summer wood portions 5 are expressed (FIG. 2d and e).

As shown in FIG. 2, the raw material veneer 2 is punched out and removed with defective parts (for example, knots, etc.).
A sheet piece 8, which is the same as the fibrous sheet forming the summer material part, is adhered to one side of the patched repair part 7.

By adhering the fibrous sheet piece 8 to the repair portion 7 in this way, it is possible to prevent the trouble of the repair piece 71 patched onto the material veneer 2 falling off during the adhesive application process. Furthermore, since the sheet piece 8 is made of the same material and the same color as the fibrous sheet used to express the summer wood part, the spring wood material veneer 2 and the summer wood material veneer 2 having the repaired part 7 to which the sheet piece 8 is temporarily glued are used. When the frits are obtained by alternately laminating, pressing and gluing fibrous sheets colored in the wood color, and slicing this, the resulting decorative veneer has a summer wood portion 5 as shown in Fig. 3. The line width becomes larger in some areas, making it possible to express a wood grain pattern with an even more natural feel. In Fig. 3, the part A where the line width of the summer material part 5 becomes thicker is the sheet piece 8.
indicates the glued part.

Next, the method for manufacturing the decorative veneer of this example will be explained with reference to test examples.

Test Example After dyeing Shinarotari veneer (material veneer) in the color of pine wood, knots in the veneer were punched out and repaired by patching (the repaired part was oval with a major axis of 10 cm and a minor axis of 7 cm).
A piece of kraft paper colored in pine wood color and coated with a two-component urethane adhesive was applied to one side of this part and adhered. Kraft paper is 0.125mm thick, long axis 15cm, short axis
A 10cm oval shape was used.

Next, apply adhesive 110~ on the repaired veneer of the material.
120 g/m ² was applied, and kraft paper colored in the same pine wood color as above was placed on the entire surface of this veneer, and several of these sheets were then pressed and glued together using release paper to form the material veneer. A composite veneer was obtained on which colored kraft paper was glued. Multiple sheets of this composite veneer are laminated with adhesive in a concave-convex mold, pressed and bonded to obtain frit.
This was sliced to obtain a decorative veneer with a wood grain pattern very similar to natural pine.

As described above, the method for manufacturing a decorative veneer of the present invention involves laminating a fibrous sheet colored in the color of summer wood and a material veneer for spring wood using an adhesive, and then pressing and bonding the veneer to prevent frizz. By slicing this,
It is possible to express summer wood that resembles a natural wood grain pattern. In particular, we punched out the defective parts of the material veneer and glued the same sheet pieces as the fibrous sheet to the patched repair parts, so the line width in the summer wood parts becomes larger in parts, giving it an even more natural feel. It can express wood grain patterns. Further, by adhering the sheet piece to the repaired portion in this way, it is possible to prevent the trouble that the repair piece patched onto the material veneer falls off during the adhesive application process.

Claims (1)

[Claims] 1. A fibrous sheet colored in the color of summer wood and a veneer of material for spring wood, in which a piece of the same sheet as the fibrous sheet is adhered to at least one side of the repaired part where the defective part has been punched out and patched, are laminated with an adhesive. A method for manufacturing a decorative veneer, which is characterized by obtaining frits by pressing and gluing, and slicing the frits.
