Description

DETAILED DESCRIPTION OF THE INVENTION When obtaining an artificial root with a symmetrical book match pattern, the present invention provides a frit which creates an artificial root that can make the seams between the patterns of the book match pattern sharp and beautiful. This is the manufacturing method.

Conventionally, when making a fritsch to obtain an artificial root with this kind of book-match pattern, a template is used to form a wavy shape on the upper surface that is symmetrical to the left and right around the valley and the deepest part A, as shown in Figure 1. A generally known method is to laminate a plurality of real roots on the mouth using an adhesive and press them together. In order to obtain an artificial real root with a symmetrical bookmatch pattern as shown in FIG. 2 using the flitch, the flitch may be cut at right angles to the real root stacking direction. However, the artificial root of the bookmat pattern obtained using the fritsch produced by the above manufacturing method has the disadvantage that the seams between the patterns are unclear and the finish is not sharp and beautiful. had. 5. The present invention has been made in view of the above-mentioned drawbacks of the conventional fritsch manufacturing method.

The present invention will be described in detail below based on the drawings. FIGS. 3 to 5 show one embodiment of the present invention.

As shown in FIG. 3, the present invention has a maximum width of 3Tfm to 8"0.
-, depth 0.5- to 1.0Tm (7) V-shaped groove 1,
Thickness O, 6TWL to 2.
It is made from wood such as White Seraya and Mangashinoro with 0mFFl.

The V-shaped grooves 1 of the roots 2 with a moisture content (weight %) of 10% to 20% are formed in a wavy shape symmetrical on the upper surface with the deepest 15 part 4 of the valley as shown in FIG. , 20 to 60 roots 2, 2, etc. are attached to the deepest part 4 of the valley on the lower template 3 made of wood, metal, etc., using a vinyl acetate resin adhesive or an epoxy resin adhesive. At the same time, the left and right groove walls 5, 5 of the V-shaped groove 1 are brought into close contact with each other, and a reverse wave-shaped shape ( In other words, the upper mold plate that forms a corrugated shape in the relationship between male and female on the lower surface is placed on the laminated real roots 2, 2, ... soil, and then heated to a pressure of 7Ki/Cr!i to 8 for 9/crllN for 20 hours. 5. Press from above and below under molding conditions for 24 hours to harden the room temperature curing adhesive.
It is a fritsch that integrates ,... The adhesive used in the present invention may be a room temperature curing adhesive as described above, or may be a thermosetting adhesive such as a phenolic resin adhesive 30 or an area resin adhesive. In this case, the pressure is 7 kg/ Hot-pressure molding may be performed under molding conditions of 1 to 8 to 9/cwi) temperature of 100° C. to 150° C. and time of 60 seconds to 200 seconds.

Further, the coating amount of the adhesive used in the present invention is suitably 6035 y/w to 2 oot/w.

The present invention is constructed as described above, and since the pattern of the veneer 2 becomes discontinuous in the V-shaped groove 1 portion where the groove walls 5 are in close contact with each other due to the integrated lamination, the pattern of the veneer 2 is discontinuous. The seams between the patterns that are approximately symmetrical on the left and right sides of the artificial veneer 6 made by cutting at right angles to the stacking direction of 2 are clear,
It has the effect of creating a sharp and beautiful finish. still,
In the present invention, it is desirable that the maximum width and depth of the V-shaped grooves be appropriately changed depending on the thickness of the veneer used and the corrugated shape of the lower mold plate, and the material of the veneer used in the above embodiment is one example. However, a veneer made of other materials may also be used.
