成材に写し出すことができない％郷の問題が生じた。Conventionally, when laminating a veneer such as a rotary veneer using an upper mold with a convex mold surface and a lower mold with a concave mold surface, the upper mold and lower mold Before clamping by
As shown in Figure m1, the degree of curvature of the stacked veneer l is the upper die 2. A state in which the degree of curvature of the mold surface of the lower mold 3 is smaller than the degree of curvature of the mold surface (the thickness of the yarn ends 1a and 1b of the stacked body l is
Since the thickness tIA) is larger than the thickness of c, when the upper mold 2 and lower mold 3 are pressed together, the edge 11°l of the stacked body l
Although a sufficient amount of pressure is applied to part b, the problem arises that insufficient pressure is applied to the central part IC, resulting in poor adhesion in this part. Therefore, as shown in Fig. 2, in the mold of the lower mold 4,
A plate 6 with a fixing rod 5 is placed with the fixing rod 5 inserted into the fixing rod insertion hole 7 of the lower mold 4, and a stacked body l is placed on this plate 6.
One idea was to bring the center portions of the bottom surfaces of the stacks into contact with each other, and press the stacked body l in that state as shown in FIG. By doing this, sufficient pressure is applied to the central part 1 of the body 1, so the problem of poor adhesion of the central IC is solved.However, in this case, 6
(2) Since the board 6 requires a certain thickness, the fine irregularities on the mold surface of the lower mold 4 cannot be reproduced on the laminated laminated wood.

のである。This invention was made in view of the above circumstances, and includes a pair of molds, one of which has a concave mold surface and the other mold has a convex mold surface, and the concave mold has a concave mold surface. The gist of this invention is a press device for laminated laminated lumber, characterized in that a thin elastic plate is stretched from one end of a mold surface to the other end of a mold surface.

第４図はこの発明の一実施例の構成図である。In other words, this press device is equipped with a mold in which a thin elastic plate is stretched from one end of the concave mold surface to the other, so the thin elastic plate can be used repeatedly, and the fine irregularities on the mold surface can be made using laminated laminated wood. Next, this invention will be explained in detail based on an embodiment. FIG. 4 is a block diagram of an embodiment of this invention.

もつ上型である。That is, in this press apparatus for laminated laminated lumber, a gold *** plate 9 is passed from one end of the mold surface to the other end of the lower mold 8 having a concave mold surface, and the vicinity of the end of the thin metal plate 9 is pressed down. The roller 10 provided at the end of the mold surface of the mold 8 is positioned on the hill, and both ends 11 of the thin metal plate 9 are fixed to the base 13 via springs 12, so that the thin metal plate 9 is rotated. I am in a state of 14 is an upper mold having a mold surface (convex surface) corresponding to the mold surface of this upper mold 8.

ＩＩＫ−戻る。With this structure, when a stack of veneers (not shown) is placed on the gold thin plate 91 and the upper die 14 and the lower die 8 start pressing, the central part of the bottom of the stack is first made of metal. Pressure is applied while in contact with the thin plate 9, and as the pressure increases, the metal thin plate 9 bends around the center of the bottom of the stacked body and along the left and right sides of the bottom to apply pressure, Finally, the metal thin plate 9 is brought into a state along the mold surface of the lower mold 8, and pressurization is performed. In addition, the thin metal plate 9 during this pressing
The bending occurs against the elasticity of the thin plate 9 itself and the spring force of the spring 12.1 Since the stack is clamped in this way, sufficient pressure is applied to the center of the stack. is added. When the clamping pressure is removed, the thin gold plate 9 returns to its original state mainly due to the spring force of the spring 12.

る。As described above, with this press apparatus, it is possible to easily obtain a laminated laminated material without any defective adhesion in the center. Furthermore, after the clamping is finished, the thin metal plate 9 automatically returns to its original state by the spring force of the spring 12, so it can be used repeatedly. Moreover, since the thin metal plate 9 is used, the fine irregularities on the mold surface of the lower mold 8 can be reproduced on the laminated laminated wood.

材に零し出すことができる。As described above, the press device for laminated laminated timber of the present invention has the following features:
It has a pair of molds, one mold has a concave mold surface, the other mold has a convex mold surface, and an elastic thin plate runs from one end of the mold surface of the mold with the concave mold surface to the other end. Since the material is stretched, a laminated laminated material with no adhesive defects in the center can be obtained, and the elastic thin board can be used repeatedly. Moreover, the fine irregularities on the mold surface of the lower mold can be spilled onto the laminated laminated wood.
