Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a decorative board by adhering a decorative board to a core material.

Conventionally, when manufacturing a decorative board by pasting a laminate decorative board (for example, a plastic print sheet adhered to a particle board) on the surface of a core material such as wooden plywood or chipboard, a V is pre-applied to the surface to which the laminate decorative board is attached. A method is adopted in which the grooves are formed by cutting and then the core material is aligned and adhered to the laminated decorative board. However, in that case, a gap 3 is created between the core material 1 and the decorative board 2, as shown in FIG. Therefore, it is extremely difficult to carry out the bonding work so as to completely avoid such gaps.

This invention has been made in view of the above circumstances, and is a decorative material that is free from the risk of creating a gap between the core material and the decorative laminate attached thereto, and that can improve work efficiency. The purpose is to provide a manufacturing method for.

That is, the present invention includes the steps of adhering one side of a core material having a polygonal cross section onto a V-grooved bendable decorative board; A step of cutting a V-groove, and (iii) a step of bending the decorative laminate through the V-groove and adhering the decorative laminate to the side surface, thereby adhering the decorative laminate to the surface of the core material. The present invention provides a method for producing a decorative material characterized by the following.

The present invention will be described below with reference to an illustrated embodiment.

First, as shown in FIG. 2, one side of the core material 12 having a square cross section is adhered to a predetermined position on the decorative board 11 via an adhesive (not shown). The decorative board 11 is, for example, a plastic sheet 11a with a pattern or the like attached to a substrate 11b (eg, wooden plywood, particle board, MDF, etc.).
Further, the core material 12 is made of wooden plywood, chipboard, etc., and is not limited to a rectangular cross section, but may have any polygonal shape (triangular or more).

Next, after performing processing to correct the thickness or width of the decorative board 11 as required, the predetermined bent portion of the decorative board 11, that is, the core, is cut using a V-cutter or the like as shown in FIG. V-grooves 13, 13' are formed by cutting the bent portions corresponding to the upper corners of the material 12. Next, an adhesive (not shown) is sprayed from above using a spray gun or the like, and then the V-groove 13 is formed at right angles using, for example, a roller press (not shown). It is bent and the decorative board 11 is adhered to both sides of the core material 12. Furthermore, as shown in FIG. 5, the V-groove 13' is further bent 90 degrees in the same manner, and the decorative board 11 is attached to the upper surface of the core material 12. Finally, a spring press (not shown) is used to press and fix the adhesive to complete the solidification of the adhesive.

According to the method of the present invention as described above, the V-grooves 13 and 13' at the bent portions of the decorative board 11 are formed so that the core material is not connected to the decorative board 11.
Since the core material 12 and the V-grooves 13, 13' are formed by cutting after being fixed on top, there is no risk of misalignment between the core material 12 and the V-grooves 13, 13'. There is no risk of creating a gap between them. Further, according to the method of the present invention, there is no need to align the bending V-groove and the core material every time as in the conventional method, so the integrated work of manufacturing decorative materials is facilitated, and manufacturing efficiency is improved. Thereby, manufacturing costs can be reduced.
