Description

[Detailed Description of the Invention] The present invention relates to a method for manufacturing artificial decorative veneers by processing raw material veneers, and its purpose and focus is to develop a manufacturing method that can easily produce artificial decorative veneers with a high yield. We aim to provide a wide range of information and contribute to the development of this field.

Conventionally, in order to obtain this type of artificial decorative veneer, adhesive was applied to one side of the material veneer to form an adhesive layer, and then multiple material veneers were stacked and pressed vertically. In addition, it is a widely known and publicly used technique to create an artificial flitch by curing the adhesive layer, and then to slice the artificial flitch into thin pieces.

However, in the above-mentioned conventional manufacturing method for artificially decorated veneers, the curing speed of the adhesive layer differs depending on the location, so long-term pressure is required to completely cure it, resulting in extremely poor production efficiency. was.

On the other hand, if you shorten the pressing time to increase production efficiency, the adhesive layer will not be partially cured, which will cause cracks in the artificial flitch and reduce the yield when slicing into thin pieces. There was a problem that it was difficult to obtain large quantities of good quality artificially decorated veneers.

The present invention is extremely novel and useful, and has been made for the purpose of eliminating all of the drawbacks of the above-mentioned conventional method for manufacturing artificially decorated veneers.

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

The present invention is based on the IQ of 111/#1 to 20txcrs width on one side of the material veneer (1) obtained by rotary cutting or slicing of logs such as Agatis wood, Labra phase, White Seraya wood, etc., and cutting to a predetermined size. Then, after forming an adhesive layer (3) on the center of the same side, a large number of veneers of skeleton material (IHI) are laminated, and the top and bottom A large number of veneers of the material (
1) (11...) are integrated to create an unevenly shaped artificial flitch (5), and then the artificial flitch (5)
If sliced, the thickness will be 0.2n to 2.0nm. An artificial decorative veneer (6) having an Off wood grain pattern can be obtained.

In the figure, (7) is a slicing blade.In the present invention, as a means for forming the adhesive layer (2), it is sufficient to simply attach an adhesive tape.

In addition, as a means for forming the adhesive layer (3), it is preferable to use a jig such as a roll coater or a flow coater.
After forming the adhesive layer (2), Ktij! An adhesive layer (3) may be formed, and K after forming the adhesive layer (3).

An adhesive layer (2) may also be formed.

Father, the material veneer used in the present invention (1) Fi may be subjected to degreasing, bleaching, and dyeing pretreatments in advance.

The method for manufacturing an artificial decorative veneer of the present invention is configured as described above, and according to the present invention, even if the pressing time is reduced, that is, even if the adhesive layer is not completely cured, the adhesive layer can be As a result, the shape of the artificial flitch is maintained, and if it is left as is, it is simply left in its natural state after compaction, rather than applying external pressure for a long period of time. The adhesive will harden and artificial decorative veneers can be obtained with good yield.

In particular, as shown in Figures 6 to 9, a large number of veneers (1
)(1)・−・− from above and below with a pair of presses (4)
Press with (4) to create the first laminate (5&), and raise the upper press (4) while keeping the #@1 laminate (5a) attached to the upper press (4) K. After pressing, a large number of veneers of material (1) (1)...- are placed on the lower press (4).
The upper press (4) is lowered to tighten the first layer.
A large number of material veneers (1) (1) - on the laminate (5a) of
When forming the artificial flitch (5) by repeating the step of integrating the second laminate (5b) several times, as in the present invention, the material veneer (1) Adhesive layers (2) (2) are formed on both side edges of the 1 central part KI! Shape the adhesive layer (3).

If you do this, the pressing time will be shorter than the time for the adhesive layer (3) to harden, and the adhesive layer (g) will be able to hold the book, the adhesive layer (g) (and the adhesive layer (g)) (or even a large number of veneers of the material (1) (1) --- - are connected, the first laminate (5m), the second laminate (5b)...
... etc., the upper press (4) K remains fixed and its shape is sufficiently maintained even if it is lifted, and the adhesive layer (3) is sufficiently cured while the pressing is repeated. It is possible to obtain an artificial flitch (5) that requires less adhesion.Of course, since it is an artificial flitch (6) that requires less adhesion, the artificial decorative veneer (6) obtained by slicing has almost no missing parts. It has an extremely negative effect on yield.
