Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for manufacturing a decorative veneer that expresses a feather pattern or the like.

[Background technology]

The conventional method for manufacturing decorative veneers that expresses a fletching pattern on the board surface is as shown in Fig. 3, in which at least two different colored veneers 1a and 1b are alternately laminated with an adhesive and pressed together. After bonding and bonding to create the first assembled fritsch 10, this is sliced to obtain sliced veneers 11, and the sliced veneers 11 are alternately stacked with the front and rear directions reversed and bonded by pressure to form the first assembled fritch 10. 2
An assembled fritsch 12 was obtained, and this was sliced from a predetermined direction to obtain a decorative veneer 13 expressing an arrow feather pattern.

However, in this method, since the slicing shown in FIGS. 3C and 3G is performed, the triangular prism-shaped portions 14 and 15 of each flitch 10 and 12 are lost, resulting in a poor yield.

[Purpose of the invention]

An object of the present invention is to provide a method for manufacturing a decorative veneer in which the loss of fritches is reduced and the yield is increased.

[Disclosure of the invention]

The method for manufacturing a decorative veneer of the present invention includes laminating a plurality of material veneers via an adhesive and bonding them by pressure.
After cutting this first assembled fritch into two pieces at a predetermined inclination angle, the cut surfaces of each piece are turned outward and the pieces are pressed and bonded together again. A plurality of sliced veneers are obtained by slicing the sliced veneers, and these sliced veneers are stacked with adhesive in the front and back directions and bonded by pressure to obtain a second assembled frit. After cutting into two pieces at a predetermined inclination angle, the cut surfaces are pressed and bonded again with the cut surfaces facing outward, and the resulting second reassembled frit is sliced from a predetermined direction.

An embodiment of the present invention will be described based on FIGS. 1 and 2. That is, the method for manufacturing this decorative veneer is roughly divided into the manufacturing process of sliced veneers shown in FIGS. 1A to 1H, and the manufacturing process of manufacturing decorative veneers from sliced veneers shown in FIGS. 2A to G. be done.

In the manufacturing process shown in FIGS. 1A to 1H, first, two types of material veneers 1a and 1b (rotary or sliced veneers) colored in different colors are alternately laminated with an adhesive and bonded by pressure. 1, an assembly fritsch 2 is created. In this case, veneers made of different materials are placed on the upper and lower surfaces of the flitch. This assembled fritch 2 is cut into two pieces at a predetermined angle inclined in the longitudinal direction to obtain block bodies 2a and 2b, which are stacked one on top of the other with their cut surfaces 3 facing outward. That is, assuming that the upper surface of the first fritch assembly 2 is A and the lower surface is B (FIG. 1C), the surfaces A and B are overlapped with each other with the cut surface 3 facing outward as shown in FIG. 1D. It's about matching. At this time, as shown in Figure E, a plurality of raw material veneers 1a and 1b are interposed between opposing surfaces A and B. In the lamination, two types of veneers of materials 1a and 1b are alternately laminated so that veneers of different materials are in contact with sides A and B, respectively, and bonded by pressure. At this time, the material veneers 1a and 1b inserted between the two block bodies 2a and 2b act as cushioning materials during pressing, and deformation and scratches on the surfaces of sides A and B prevent adhesion. This prevents adhesive failure from occurring.

Thus, a first reassembled flitch 4 is obtained. Next, this frit 4 is sliced parallel to the longitudinal direction to obtain a sliced veneer 5 as shown in FIG. 1H. This sliced veneer 5 can be used as a decorative veneer by itself, but in order to obtain a fletching pattern, the front and back of this sliced veneer 5 are alternately reversed to form a decorative veneer. As shown in the figure, the second assembled fritches 6 are laminated with an adhesive and bonded by pressure.
Create. This assembled flitch 6 is cut at a predetermined inclination angle in the width direction to form two block bodies 6a, 6.
b is obtained, and in the same manner as above, a plurality of sliced veneers 5 are cut between them with the cut surfaces 7 facing outward.
These are used as cushioning materials and are interposed and laminated so that the front and back directions are alternately oriented in opposite directions. This is pressed and bonded to obtain a second reassembled fritsch 8, which is then sliced parallel to the longitudinal direction to form a decorative veneer 9 with a fletching pattern.
is obtained.

In this way, the assembled fritches 2 and 6 are divided into two parts at both stages when creating the sliced veneer 5 shown in FIG. 1 and when creating the decorative veneer 9 shown in FIG.
Since the reassembled fritches 4 and 8 are formed by cutting the frits into two pieces with the cut surfaces 3 and 7 facing outward, there is no loss that occurs when slicing the fritches as in the prior art, and the yield is significantly improved.

In this embodiment, a plurality of veneer plates 1 are inserted between the two block bodies obtained by cutting the assembled fritches 2 and 6.
a, 1b or sliced veneer 5 was interposed,
Single plates 1a and 1b made of the same material on the upper and lower surfaces of the fritchi
Alternatively, when the sliced veneer 5 is arranged, only one veneer different from the sliced veneer 5 may be interposed. In addition, the material used is veneer 1a,
1b is not limited to only two types, and it is possible to combine veneers of many types of materials to create a beautiful fletching pattern.

〔Effect of the invention〕

According to the present invention, a reassembled flitch is created by cutting the assembled fritch into two parts with the cut surfaces facing outward, thereby eliminating losses that occur when slicing the fritches, thereby significantly improving the yield. Further, since the process of obtaining a sliced veneer from a raw veneer and the process of obtaining a decorative veneer with a fletching pattern from a sliced veneer are the same, there is an advantage that manufacturing is easy. Especially when automating the process, equipment and machinery can be shared between the two processes, reducing costs. Moreover, since this manufacturing method is used, another decorative veneer (sliced veneer) can be obtained in an intermediate process.
