れている。2. Description of the Related Art A typical example of a decorative laminated plywood in which a thin veneer veneer utilizing the aesthetic effect of natural heather is bonded and integrated on the surface of a plywood plate is a commercially available flooring. The conventional product is manufactured through a process as shown in FIG.

る。However, in the above-mentioned conventional manufacturing method, when the first adhesive (11) is applied in a large amount, when the paper (12) is attached and pressure-bonded to the base plate plywood (10), the paper is bonded. Since it permeates (12) and oozes upward, it adheres to the surface of the pressure roll (13) or the flat plate press and stains it, so the coating amount must be specified to be small. As a result, the first adhesive (11) is impregnated only on a part of the back surface of the paper (12).

表面一部だけにしか含浸されない結果となる。Therefore, in order to compensate the adhesive strength of the decorative veneer (15) by the first adhesive (11), the second adhesive is used.
When a large amount of the adhesive (14) is applied, the paper (12)
When the decorative veneer (15) is attached to the veneer at the time of hot pressing, the thin veneer (15) penetrates upward through the conduit or the like of the veneer, and then the decorative veneer (15) is coated with a colored paint. When performing, the exuded adhesive (14) hinders the fixation of the colored paint and causes uneven coloring, so that the applied amount of the second adhesive (14) must be adjusted to be small. This results in the second adhesive (14) being impregnated only on a part of the surface of the paper (12).

ないので、著しく煩雑であり、量産性や汎用性に劣る。As a countermeasure for preventing the occurrence of the coloring unevenness, there is a method of coloring the second adhesive (14). However, in this case, every time the color tone of the decorative veneer (15) changes, the second adhesive (14) is changed. Since various kinds of coloring must be prepared in accordance with the conditions, the method is extremely complicated, and is inferior in mass productivity and versatility.

い。Further, in the above-mentioned conventional manufacturing method, the plywood (1
The first step (i) of attaching the paper (12) to the paper (0) and the second step (ii) of attaching the decorative veneer (15) to the paper (12) are separated and independent as a production line or a machine. As a result, it is not possible to mass-produce the decorative bonded plywood efficiently in a short time, and the first adhesive (1) in the first step (i) is not used.
Unless 1) is dried and hardened, the operation of attaching the decorative veneer (15) in the second step (ii) cannot be performed.
