DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an artificial nameplate in which a nameplate is artificially manufactured by laminating a large number of veneers in a bent manner and slicing the same. 2 and a lower mold 4 whose upper surface is a bent surface 3, a large number of veneers 5, 5...
- is pressed to form a flitch 6 in which veneers 5゜5... are laminated, and the upper and lower parts of the flitch 6 are placed in upper and lower molds 2 and 4.
The upper and lower parts of the flitch 6 cut at the cutting surfaces 7 and 8 that are inclined with respect to A large number of veneers 5, 5... are pressed between the bent surface 11 of the mold 10 and the bent surface 12 of the lower mold 9 which has been bent by the bent surface 1 of the upper mold 2. The present invention relates to a method for producing an artificial nameplate, which is characterized by forming a flitch 13 in which veneers 5, 5, . . . are laminated, and slicing this flitch 13.

A flitch 6 is formed by laminating and pressing a large number of veneers 5 between an upper mold 2 whose lower surface is a curved surface 1 and a lower mold 4 whose upper surface is a curved surface 3, and the flitch 6 is sliced. Conventionally, the production of artificial nameplates by this process was carried out using the steps shown in FIG.

That is, as shown in FIG. 1a, a large number of veneers 5 are pressed between the upper and lower molds 2 and 4 to form a flitch 6 in which each veneer 5 is bent into a wavy shape and laminated. horizontal cutting surface 14,
The flitch 6 is cut at 15, and the upper and lower parts of the flitch 6 are used as a lower mold 16 and an upper mold 17, and horizontal cutting surfaces 14 and 1 are formed.
Slice the flitch 6 between 5 to obtain the nameplate.

After this, a curve is formed between the bent surface 22 of the upper mold 17 formed by the bent surface 3 of the lower mold 4 and the bent surface 23 of the lower mold 16 formed by the bent surface 3 of the upper mold 2. As shown in Figure 1, the veneer 5 is press-molded to obtain a flitch 18.

At this time, an adhesive 19 is applied to the lower surface of the upper mold 17, and the upper mold 17 is laminated as a part of the flitch 18.

The flitch 18 is cut along the horizontal cutting surface 35 to separate the lower part of the flitch 18 as the upper mold 20.

The rest can be sliced to obtain a nameplate.

Furthermore, the veneer 5 is press laminated between the upper mold 20 and the lower mold 16 used in the process shown in Figure 1 to form the flitch 21, and the process C in Figure 1 is repeated. Let's do it.

The nameplate obtained above is manufactured by horizontally slicing the flitches 18 and 21, which are the veneer 5 bent and deformed. , a nameplate with a luxurious feel can be obtained.

However, with this method, the lower mold 16 will be formed in the same shape as the upper mold 2, the upper mold 17 will be formed in the same shape as the lower mold 4, and the upper mold 20 will be formed in the lower mold 16
It will be formed in the same shape as the flitch 6.18,
The wavy deformed shapes of the veneers 5 in 21 were all molded into the same shape, and the wood grain patterns of the nameplates obtained by slicing the flitches 6.1B and 21 were all the same.

Therefore, in order to produce various wood grain patterns, it is necessary to prepare a large number of different types of upper and lower molds 2 and 4, which is disadvantageous.

In order to solve this problem, a method has been considered in which the flitch is cut with a slice plane 24 at an inclined angle as shown in FIG. 2, and the wood grain pattern is varied by changing this angle. In this case, the portion indicated by A in FIG. 2 is wasted, resulting in poor yield.

The present invention has been made in view of the above points, and it is possible to obtain nameplates expressing various wood grain patterns without the need to use many types of upper and lower molds, and without the risk of deteriorating yield. The purpose of this invention is to provide a method for manufacturing an artificial nameplate.

The present invention will be explained in detail below with reference to Examples.

Bent surfaces 1 and 3 are formed on the lower surface of the upper mold 2 and the upper surface of the lower mold 4 so that the convex portion and the concave portion correspond to each other. The upper and lower molds 2 and 4 are stacked up between the upper and lower molds 2 and 4 with adhesive interposed between the plates 5, and the upper and lower molds are pressed by the lower support plate 25 and the upper holding plate 26 as shown in FIG. Press veneer 5°5... with molds 2 and 4.

In this way, the veneers 5, 5, . . . are deformed in waves along the curved surfaces 1, 3 to obtain a flitch 6 in which they are laminated and integrated.

Next, as shown in FIGS. 4a and 5, the upper and lower parts of the flitch 6 are cut with cutting surfaces 7 and 8 that are inclined in the width direction or longitudinal direction with respect to the upper and lower molds 2.4 and are parallel to each other. .

By cutting in this way, a lower mold 9 and an upper mold 10 are obtained at the upper and lower parts of the flitch 6.

Bent surfaces 11 and 12 are formed on the upper surface of the lower mold 9 and the lower surface of the upper mold 10 by the bent surfaces 1 and 3 of the upper mold 2 and the lower mold 4, respectively.

Next, arrange the upper mold 10 and the lower mold 9 as shown in Figure 4 so that the cut surfaces 7 and 8 are in a horizontal state.
The veneers 5, 5, .

At this time, the upper and lower molds 9, 10 are reinforced by pasting reinforcing materials 27 made of epoxy resin or the like to the sides of the upper and lower molds 9, 10, as shown in FIGS. 7 and 8a and 8b.

By arranging the upper and lower molds 9 and 10 horizontally in this way, the upper and lower molds 9 and 10 are arranged in an inclined state with respect to the state formed by the upper and lower molds 2 and 3. In the embodiment shown in Figure 4, the convex portions of the bent surfaces 11 and 12 of the upper and lower molding molds 9゜10 protrude more than the convex portions of the bent surfaces 1 and 3 of the upper and lower molds 2゜4. The recessed portions of the curved surfaces 1 and 3 are recessed more than the recessed portions of the curved surfaces 1 and 3.

Therefore, the flitch 13 formed from this is obtained by applying large wave-like deformation to the veneer 5, and is obtained by applying large wave-like deformation to the veneer 5.
A wave-like deformation different from that of the flitch 6 is applied to the veneer 5.

Thereafter, the upper and lower parts of the flitch 13 obtained in this way were further cut along the horizontal cutting plane 28°29 to obtain a lower manufacturing mold 30 and an upper manufacturing mold 31 at the upper and lower parts of the flitch 13, as shown in FIG. 4C. The flitch 32 is formed by pressing and laminating the veneers 5 between the upper manufacturing mold 31 and the lower manufacturing mold 30 as shown in FIG.

At this time, adhesive 19 is applied to the lower surface of the upper manufacturing mold 31 to integrate the upper manufacturing mold 31 as a part of the flitch 32.

The lower part of the flitch 32 obtained in this way is
3 to obtain an upper mold 34 at the bottom of the flitch 32.

This upper manufacturing mold 34 and the lower manufacturing mold 3 used for the molding of FIG. 4C
0, and the flitch is formed in the same manner.

In order to obtain the nameplate, the B part between the horizontal cut surfaces 28 and 29 of the flitch 13 obtained in FIG. 4 S, and the C part above the horizontal cut surface 33 of the flitch 32 obtained in FIG. It is obtained by slicing horizontally as shown in FIG.

In order to manufacture a nameplate with a wood grain pattern different from the wood grain pattern of the nameplate obtained in this way, the cut surface 7 in the process of FIG.
, 8 to form upper and lower molding molds 9, 10, and then obtain the flitch and nameplate in the same process as shown in FIG. 4, c.

Note that the upper and lower molds 2 and 4 are installed in a press machine in a state in which they are parallel and inclined with respect to the horizontal plane.
A flitch 6 is formed in between, and the upper and lower parts of the flitch 6 are cut using horizontal cutting surfaces 7 and 8 (that is, they are inclined relative to the upper and lower molds 2 and 4) to form upper and lower molds 9 and 10. You can also get it.

In addition, as a means to achieve the same effect as above, the flitch obtained as the lower mold 9 and the flitch obtained as the upper mold 10 in the step shown in FIG. You can also consider slicing.

As described above, according to the present invention, when the upper and lower parts of the flitch formed between the upper and lower molds are cut with a cutting surface inclined with respect to the upper and lower molds to obtain the lower mold and the upper mold, the cutting process is performed. By obtaining upper and lower molds by varying the angle of inclination of the surfaces, it is possible to obtain various bent shapes for the flitch formed between the upper and lower molds, and various shapes can be attached to the nameplates obtained by slicing the flitch. It is possible to produce nameplates with various wood grain patterns without the need to prepare many types of upper and lower molds.

Moreover, since the flitch is not diagonally sliced to obtain various grain patterns, there is no risk of poor yield.
