When applying pressure to 1B, it is necessary to use a pair of molds (21) with a convex surface and a concave surface as shown in Figure 1, and an adhesive to be used on the outside. It is necessary to use C7 gold, which has a high degree of plasticity.Also, a urethane-based adhesive is used as a bonding agent, but this bonding agent is prone to damage due to the scum created by foaming. There is a high risk of causing problems.Therefore, it is necessary to remove the scum to prevent the problem from occurring.
- Since the convex and concave surfaces of the mold 41 (2nd Jin are parallel), even if the mold is tightened and temporarily attached, the tension is loosened and the final tightening is performed for the old layer, but each veneer does not Pressure is applied to the center and side edges at the same time, or 94S1 (b

The present invention, which provides a pressure welding method, will be described below with reference to the drawings. 2nd 1 middle + In Hayabusa plate 1 (2 is the mold, and the upper mold is convex in 2 + 12 +) The mold is concave. A plate (3) is placed on the plate to absorb the elastic force in the direction where the curvature becomes smaller.

Finally, as shown in Fig. 2(b), the lower mold (21) will fit into the concave ThK, and each of the laminated veneers The applied pressure increases.For this reason, each veneer (1
) is squeezed out from both sides of each veneer to form a spring (31 is a laminated lumber obtained by gluing the veneer to the hem that fits the shape of the mold (2j) with one pressure). The laminated decorative veneer obtained by slicing this laminated wood, especially the batash that exhibits a wood grain pattern on its surface, does not have unnecessary roughness.

になる。If the number of veneers to be laminated [110] is extremely large and cannot be pressure-adhered to the clothes, the veneers are glued in several parts, but in this case, as shown in Part 3 of II'i. Of the veneer (la) already pressure-bonded to the veneer (la) and the veneer (1b) to be seen next, if you put the next veneer (1b) to be glued on K1 layer on the board (3), it will be temporary. Even during the tightening stage, the pressure increases from the center, making it possible to remove waste.

As shown in the figure, by using a plate screw with the center part protruding upwards (3+), in this case as well, the pressure in the center part increases first not only during final tightening, but also from the first press tightening, and then gradually Both @l
Since the pressure at the ends is high, no debris builds up.

ずれを招くことなく仮締めを行なえろ。By the way, when forming a curved laminated wood using m(2' with an uneven surface of 1), if the curvature of mold (2j is large), the veneer fil will not fit m There is a large gap between the plate (1) and the plate (1), which tends to cause misalignment when loading or applying pressure.However, if you use a plate spring (31) as shown in the IP12 diagram, Since ~jKFJIIvl with the veneer (11) does not occur, temporary tightening can be performed without causing the above-mentioned deviation.

：Ｊクバックを生じないという利点も有する。Further, during this temporary tightening, the following means may be used to improve the fit between the mold (2) and the veneer (1). In other words, 4! J, As shown in Fig.
Water is applied to one surface of the llj or sprayed with water using a sprayer (6). In the figure () is an O-lu coater for applying adhesive. The back surface of the veneer (11) that has absorbed moisture is curved as shown in Figure 6 as the back surface of the board (11) stretches, making it more compatible with the concave mold (2). As shown, make a cut (8,
It is also possible to make it easier to bend by inserting a hole, or to make use of the nose crack of the veneer (1). In these cases, it also has the advantage of not causing smearing after depressurization.

方の型（２）を押し付けてル締めを行なう。In addition, it is possible to prevent misalignment and increase the number of pillars per layer without being restricted by the hot life of the adhesive due to the fact that each veneer (1) coated with adhesive is polished one by one. From the two points of view, the following may be used. That is, as shown in Fig. 8 and below, the lower mold (2) and the guide plates (11) on both sides are placed in a cypress into which liquid adhesive (9) is placed, and the kite plate (11) is placed 99 -: Make it so that it can be moved with the help of the cypress.

As shown in Figure (c), press the upper mold (2) to perform the tightening.

くことができて接着不良を招くことがないものである。As described above, in the present invention, a leaf spring is interposed between the mold and the veneer, and the center part of the leaf spring is brought into elastic contact with the center part of the veneer. Since the pressure is increased from the top to the primary side end, the debris and air generated by the foaming of the adhesive between each bond moves from the pressure distribution to the side and end and is squeezed out from the side end. It is possible to easily and reliably remove the waste with a simple structure of a rod with a leaf spring interposed therebetween, and there is no possibility of adhesion failure.
