Conventionally, in order to express a bamboo heather pattern on the surface of a decorative veneer, as shown in FIG.
is made, and one side of this composite veneer 14 is embossed with an embossing roll 15 to give unevenness. After that, a plurality of embossed composite veneers 14 are stacked together with an adhesive and bonded by pressure using predetermined molds 16 and 17 to obtain a composite fritchi 18, which is then sliced to form a decorative piece having a bamboo heather pattern. I was creating veneer 19.

し、次の単板積載時に積載ずれをおこすという問
題があつた。 However, in such conventional methods,
The moisture content of the raw material veneer 12 is kept low so as not to cause defects such as sagging when slicing the composite fritsch 18, and to prevent the grooves formed by embossing from restoring and disappearing easily. As shown in FIG. 3, there was a problem in that the embossed composite veneer curled, causing a loading misalignment when the next veneer was loaded.
この発明の目的は、複合単板がエンボス加工に

である。
An object of the present invention is to provide a method for manufacturing decorative veneers that prevents composite veneers from curling due to embossing and prevents shifting when stacking composite veneers.
この発明の化粧単板の製造方法は、素材単板の
両面に着色シートを貼着して複数単板を得る工程

ある。
The method for producing a decorative veneer of the present invention includes a step of attaching a colored sheet to both sides of a material veneer to obtain a plurality of veneers, and a step of embossing both sides of the composite veneer to give unevenness to both sides. , a step of stacking embossed composite veneers and raw material veneers alternately through an adhesive and bonding them by pressure to obtain a composite frit; and a step of slicing the composite frit.
すなわち、この発明は、両面に着色シートを貼
着した複合単板の両面をエンボス加工することに
より、それぞれの面で互いに反対方向にカールし
ようとする力が相互に打ち消される結果、カール

めることができる。また、両面にエンボス加工す
るために、エンボス加工する単板が従来の1/2で
よく、作業能率も大幅に向上させることができ
る。 That is, in this invention, by embossing both sides of a composite veneer with colored sheets pasted on both sides, the forces that tend to curl in opposite directions on each side are mutually canceled out, resulting in a flat, curl-free surface. This is to obtain a composite veneer with a high quality. Therefore, it is possible to obtain an assembled frit without causing loading deviation in the next process, and productivity can be improved. In addition, since both sides are embossed, the number of veneers to be embossed can be reduced to half of the conventional veneer, greatly improving work efficiency.
以下、第１図に基づいてこの発明の方法を説明

９，１０で圧締接着して集成フリツチ１１を得
る。得られた集成フリツチ１１は、従来と同様に
スライスして化粧単板を得る。 The method of the present invention will be explained below based on FIG. First, as shown in the figure, a pair of roll coaters 2 and 2' are used to apply adhesive 3 to both sides of the raw material veneer 1.
Apply 4 at the same time. The material veneer 1 used is one that has been colored in a desired color in advance. After applying the adhesive, a colored sheet 5 such as a non-woven fabric and a release paper 6 are sequentially placed on both sides, and pressed by a press 7 to obtain a composite veneer 8 in which colored sheets 5 are pasted on both sides of the material veneer 1. . This composite veneer 8 is passed between a pair of embossing rolls 9, 9' to emboss both sides.
Next, a large number of material veneers 1 and embossed composite veneers 8, each coated with adhesives 3 and 4 on both sides by a pair of roll coaters 2 and 2', are stacked alternately and bonded by pressure using upper and lower dies 9 and 10. Then, a fritch assembly 11 is obtained. The obtained fritch assembly 11 is sliced in the conventional manner to obtain a decorative veneer.
このように、使用する素材単板１のうち1/2の
素材単板１の両面に同時に着色シート５を貼着し
て複合化するので、従来と比較して複合化工程が
１／２に短縮され、離形紙６の使用も1/2になる。さ
らに、複合単板８の両面を同時にエンボス加工す
るので、エンボス加工する単板も従来の1/2でよ
く、生産性、作業性を大幅に向上させることがで
きる。 In this way, since the colored sheet 5 is simultaneously pasted on both sides of 1/2 of the material veneers 1 to be used, the compositing process is reduced to 1/2 compared to the conventional method. It is shortened, and the use of release paper 6 is also halved. Furthermore, since both sides of the composite veneer 8 are embossed at the same time, the number of veneers to be embossed can be halved compared to the conventional one, and productivity and workability can be greatly improved.
