Abstract

PURPOSE:To completely conceal linting and joint in plywood with decorative sheet without floating by a method wherein the decorative sheet is pasted to the surface of base material, which is lined with flexible sheet and at the predetermined places of which grooves are provided, and, by pressing the decorative sheet at the places of the grooves on the base material with projected beads, the decorative sheet is pushed in the grooves. CONSTITUTION:Flexible sheet 4 is lined through adhesive on the rear surface of base material, on the front surface of which a plurality of grooves 3 having V-shaped crosssection are provided in parallel to one another with a cutter, a grinder or the like. On the front surface of the base material 5, on the front surface of which the grooves 3 are formed, decorative sheet 7, on the rear surface of which adhesive 6 is applied with a knife coater 10, is fixed through a reversing roll 11A by pressure with a pressure roll 11. Next, before the hardening of the adhesive 6, the decorative sheet 7 is pushed with a pushing-in roll 12 in the grooves 3 of the base material 5 until the decorative sheet 7 reaches the bottoms of the grooves 3. Thus, decorative sheet 2 having the favorable external appearance is produced. At the same time, the decorative sheet 2 can be bent at the place of the groove 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a decorative material which can be bent through a groove.

[0002]

BACKGROUND OF THE INVENTION For example, an elliptical table (1) shown in FIG.
In this case, the decorative material (2) is stretched on the side surface.
A groove (3) having a V-shaped cross section is provided in (2), and is bent along the elliptical shape of the table (1) through the groove (3).

[0003]

2. Description of the Related Art In order to manufacture a decorative material (2) having a groove (3), a wooden base material (5) lined with a flexible sheet (4) such as cardboard as shown in FIG. 9 is used. A decorative sheet (7) is adhered to the surface with an adhesive (6), a masking sheet (8) is further adhered onto the decorative sheet (7), and the base material is cut with a cutter as shown in FIG.
Form a groove (3) having a V-shaped cross section integrally with the masking sheet (8) and the decorative sheet (7) in (5), or on both sides of the groove (3) as shown in FIG. Usually, after applying the coating (9) of the same color as the decorative sheet (7), the masking sheet (8) is peeled off as shown in FIG. The decorative material (2) manufactured in this way can be bent at the groove (3) as shown in FIG.

[0004]

However, it is extremely difficult to adjust the color of the decorative sheet (7) and the paint used for the coating (9) to the same color by the above-mentioned conventional manufacturing method, and the surface of the decorative material (2) and the groove ( There is a color difference with the part of 3), and when the groove (3) is cut, fluffing occurs on the side surface of the groove (3), and the base material
When plywood is used as (5), the problem is that the seams between veneer layers are exposed on the sides of the groove (3) and that such fluffs and seams are not easily covered by the coating (9). Occurs. As shown in FIG. 14, the decorative sheet (7) is used as a base material.
If the groove (3) of (5) is applied, the fluff and seams are surely concealed, but to apply the decorative sheet (7) to the groove (3), the decorative sheet ( When attaching 7) to the base material (5), a vacuum is drawn from the back side of the base material (5). However, even if the decorative sheet (7) is evacuated in this way, the decorative sheet (7)
It is difficult to reach the bottom of the groove (3) of the substrate (5),
Floating occurs on the decorative sheet (7).

[0005]

As a means for solving the above-mentioned conventional problems, the present invention provides a groove (3) at a predetermined position of a base material (5) lined with a flexible sheet (4), The base material (5)
A decorative sheet (7) is attached to the surface, and the groove (3) of the base material (5) is attached.
There is provided a method for producing a decorative material (2) in which the decorative sheet (7) is pushed into the groove (3) by pressing the decorative sheet (7) with the convex ridges (12A) at the above position.

[0006]

[Function] In the present invention, the decorative sheet (7) is provided in the groove (3) of the substrate (5).
Since the fork (12A) is forcibly pushed in, the decorative sheet (7) surely reaches the bottom of the groove (3) and does not float. Then, the fluffing in the groove (3) of the base material (5) and the seam in the case of plywood are completely covered by the decorative sheet (7).

[0007]

EXAMPLES The present invention will be described with reference to one example shown in FIGS. 1 to 5. The back surface of the substrate (5) is lined with a flexible sheet (4) with an adhesive (10). Examples of the base material (5) include plywood, particle board, hard board, laminated wood,
Wood fiber board, wood board such as veneer or fiber cement board,
The flexible sheet (4) is an inorganic material such as gypsum board and calcium silicate, and is, for example, cardboard, non-woven fabric, flexible plastic sheet or the like.

A plurality of grooves (3) having a V-shaped cross section are provided in parallel on the base material (5) by a cutter, a grinder or the like as shown in FIG. The cross-sectional shape of the groove (3) may be U-shaped or U-shaped other than V-shaped. As shown in FIG. 5, the surface of the base material (5) having the groove (3) formed on the surface thereof is coated with a decorative sheet (7) by a knife coater (10).
Adhesive (6) is applied to the back side and then the reversing roll (11
The decorative sheet (7) is pressure-bonded by the pressure-bonding roll (11) via A). This state is shown in FIG. The decorative sheet
(7) is a paper, a plastic sheet, or the like, whose surface is colored or patterned.

When the decorative sheet (7) is pressure-bonded in this manner, the decorative sheet (7) is pushed into the groove (3) of the base material (5) by the pressing roll (12) before the adhesive (6) is cured. It is pushed in and the decorative sheet (7) reaches the bottom of the groove (3) as shown in FIG. A plurality of convex ridges (12A) are formed on the pushing roll (12), and the convex ridges (12A) are formed on the base material (5).
Is located at a position corresponding to the groove (3) of the
By this, the decorative sheet (7) is pushed into the groove (3).
When the flexible sheet (4) is breathable at the same time as the decorative sheet (7) is pushed by the pushing roll (12), it is a base material.
A vacuum may be drawn from the back surface of (5).

In this way, the decorative sheet (7) is the base material (5).
A cosmetic material that is desirable in appearance to the bottom of the groove (3)
(2) is manufactured, and the decorative material (2) can be bent at the location of the groove (3). For example, the decorative material on the side surface of the elliptical table (1) as shown in FIG. Used as wood (2).

Other than the above embodiment, a pushing device (15) having a plurality of pushing discs (13) connected by a shaft (14) may be used instead of the pushing roll (12) as shown in FIG. In this case, the edge of the pushing disc (13) becomes a convex (13A).

[0012]

Therefore, according to the present invention, a foldable decorative material having a desirable appearance is manufactured.
