Description

[Detailed description of the invention] [Technical field] When cutting a pair of upper and lower molds, the size of the cut 1j11 tool tip shape waveform produced on the curved surface of the mold is changed at any location of the upper and lower molds. After that, a large number of laminated wood veneers are pressed together with the upper and lower molding molds to form an artificial flitch, and the artificial flitch is sliced to obtain an artificial decorative veneer with a wood grain pattern. It is something.

[Background technique fishing]

Conventionally, when cutting a pair of upper and lower molds used to obtain this type of artificial decorative veneer, the curved surface of the mold is processed and formed with approximately the same cut 1411 tool tip shape waveform. Ta. For this reason, the annual rings of the artificially decorated veneer obtained generally have approximately the same shape. Therefore, we added unevenness to the wood veneer boards themselves, stacked them, pressed them together to form an artificial flitch, and cut the artificial flitch into slices 1'.
The method of obtaining an artificial decorative veneer that has an uneven pattern on a part of the annual ring is a widely known technique. This method has the disadvantage that it is an extremely inefficient operation since it requires adding irregularities.

[Purpose of the invention]

The present invention eliminates all of the drawbacks of the conventional methods for producing artificially decorated veneers, and provides society at large with a method for producing artificially decorated veneers with a desired wood grain pattern and annual ring pattern in an extremely efficient manner. The aim is to contribute to the development of this field.

[Structure of the invention]

The present invention is characterized in that when a pair of upper and lower molds made of a metal or resin-impregnated hard block is machined, a waveform in the tip shape of the cutting tool (2) that is generated on the curved surface (1) of the mold is produced. (3) The size of the upper and lower molding u (4) is changed at any location in (4). At this time, the tip shape waveform (3
) is preferably changed at corresponding positions on the upper and lower molds. Next, logs that are unsuitable for use as decorative materials due to unclear grain patterns or monotonous colors, such as Agatis wood, Aius wood, Labra wood, Tepa wood, White Seraya wood, and Shina wood, are rotary cut. 1, or thickness 0 obtained by slicing and cutting to a predetermined size.
．． After pre-treating the 2% to 2゜Ox wood veneer (5) as necessary, such as degreasing, bleaching, and hot water washing,
Perform a dyeing process to obtain the desired color. Next, a large number of colored wood veneers (5) (5) are laminated with adhesives such as urea resin adhesive, phenol resin adhesive, urethane resin adhesive, etc. After pressing with the pair of upper and lower forming molds (4) to cure the adhesive and integrate to form an unevenly shaped artificial flitch (6), the artificial flitch (
By slicing the fragrance 1, an artificial decorative veneer (8) having an uneven pattern of tree rings (7) inside the wood grain pattern is obtained.

In addition, as a means for changing the tip shape (wave type) of the cutting tool (2), there is a possibility of changing the feed pitch of the cutting tool (2) or changing the tip diameter of the tool used.

〔Effect of the invention〕

The present invention involves changing the size of the cutting tool tip shape waveform that occurs on the curved surface of the mold when cutting a pair of upper and lower molds at an arbitrary location on the upper and lower molds, and then laminating a large number of wood veneers. are pressed and integrated with the upper and lower molding molds to form an artificial flitch, and the artificial flitch is sliced into a sliver 1, so it is extremely easy to create an uneven pattern in the wood grain pattern.
“■It has the effect of making it possible to obtain an artificial decorative veneer having three worlds.
