Description

[Detailed Description of the Invention] The present invention relates to a method for manufacturing artificial decorative veneer, and its purpose is to effectively utilize veneer pieces of various sizes to create a unique and natural-looking veneer. This book aims to contribute to the development of this industry by providing a general method for easily producing artificial decorative veneers with wood grain patterns.

Conventionally, in order to obtain this type of artificial decorative veneer, a large number of material veneers of the same size are created, a colored ink layer is formed on one side of the material veneer using a transfer method, and then the colored ink layer is applied. A large number of veneers of this material are laminated in the same direction via adhesive, and pressed from above and below, and the adhesive is allowed to harden to create 7 rich pieces with uneven shapes. The widely known and publicly used production method was to slice the material into thin pieces.

However, in the conventional manufacturing method for artificial decorative veneers mentioned above from Kei, the material veneers used must be of a certain size, and because there are restrictions on the material veneers that can be used, the yield is extremely high. Furthermore, the grain pattern of the artificially decorated veneer obtained is monotonous and lacks a natural feel, which is far from the grain pattern of natural wood. It was.

After a long period of research and development, the inventors who achieved this invention
This method solves all of the drawbacks of the conventional artificially decorated veneer manufacturing method.

Hereinafter, the present invention will be explained in detail based on the embodiments shown in FIGS. 1 to 6.

The present invention is an amorphous material unit of various sizes obtained by removing defects such as knots, stains, and insect holes from rotary veneer obtained by rotary cutting logs of Agatis wood, Labra wood, and White Seraya wood. Create a large number of plate pieces (1). Next, a colored ink layer (3) having the same color as the summer wood of the desired natural tree is applied to the surface of the sheet (2) having mold releasability such as a polypropylene resin sheet or a polyethylene resin sheet.
) and apply an adhesive (4) such as area resin adhesive, phenol resin adhesive, urethane resin adhesive, etc. on the colored ink layer (3). (5) in the figure is an adhesive coating device. It is. The aforementioned material veneer piece (1) (1) prepared in advance on the aforementioned sheet (2)...
... are juxtaposed and fixed. Next, the sheet (2) is removed, and a single material IF (6) made of a large number of material veneer pieces (1) arranged in series is created. In the figure (η is a pressure roll, (8) is a conveyor. In addition, the material veneer piece (1)
It is desirable that the interval between (1) be less than KLO■ for electrification of the pressure car during flitch molding in the subsequent process. Also, when fixing the material veneer pieces (1) side by side, fill the gap between the adjacent material veneer pieces (1) with adhesive.
It is desirable to apply sufficient pressure.-6 Next, the material veneer (
When a large number of 6) are laminated with adhesives such as area resin adhesive, phenolic resin adhesive, urethane resin adhesive, etc. While pressing with a press, the adhesive is cured to create an uneven shape (7).
Then, apply the 7 retouches (9) to a thickness of 2m to L.
By slicing a thin piece of OW, an artificially decorated veneer (2) with a unique and natural feel can be obtained. In the figure (
! The force is a slicing blade. Furthermore, it is desirable that the material veneer piece (1) used in the present invention be colored in advance to match the color of the desired spring wood of natural wood.

The present invention is constructed as described above, and according to the method for manufacturing artificial decorative veneers of the present invention, veneer pieces of various sizes can be used, and the yield is improved. The wood grain of the veneer has the effect of giving it a richly varied and natural feel. The effects of the present invention will be explained below based on examples. Example 1 As shown in Figure 6. A material veneer piece 3 (1m) (1m) =-= with an acute angle shape is placed and fixed side by side to create a material veneer (6m), and the material veneer (6m) is used to create an uneven shape. By making 7 rich pieces and slicing the flitches, it is possible to obtain an artificially decorated veneer (10 m) with a bamboo-grained wood grain pattern as shown in Fig. 7.

Example 2 As shown in Fig. 8, a piece of veneer material (lb) with an acute angle () in the center and a piece of veneer material (lb) with a rectangular shape on both sides (1e) (1 Place @),
A material veneer (6b) is created by juxtaposing and fixing, and the material veneer (6b) is
6b) to create an uneven-shaped flitch and slice the wrinkled flitch to obtain an artificial decorative veneer (1ob) with a bamboo-grained wood grain pattern in the center as shown in Figure 9.
