DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a wood laminated board in which a plurality of wood boards are assembled and their ends are joined.
The present invention also relates to a manufacturing apparatus used in the method, and a wooden decorative board which is commercialized as a floor material, a wall material, and a ceiling material using the wooden laminated board obtained by the method.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
A plurality of wooden boards (b) are placed side by side on top of each other, and in this state, the plurality of wooden boards (b) are pressed together from the side to assemble. A method of manufacturing a wood laminated board in which the ends of (b) are joined to each other is known.

In this case, on both sides of the base (a), a pressing machine (c) composed of an air cylinder, a hydraulic cylinder, a simple hydraulic pressing machine or the like is provided. The plurality of wooden boards (b) placed side by side on the base (a) are pressed and assembled from both sides. When joining the ends of the plurality of wood boards (b) in the assembled state, an adhesive tape (d) is attached between the upper surfaces of the respective wood boards (b).

[0004] Further, as shown in FIG. 8, a wooden laminated board (e) obtained by the above-described manufacturing method is provided on a surface of a substrate (f).
