もよい。In general, it is preferable that the fiber boards to be laminated have substantially the same density as each other. However, it is preferable that the fiber boards be formed on the inner peripheral surface of the frame material (the side face to be fitted with the mirror plate) later. When it is desired to impart strength to the front and back surfaces of the nested edge to be formed, the fiber boards laminated on the front and back surfaces of the core material may have a high density.

決定される。Then, the fiberboards 1 are laminated with an adhesive therebetween, and heated and pressed by a press or the like to form a wooden fiberboard laminate 2, which is cut to an arbitrary width in the longitudinal direction to obtain a wooden fiberboard. The fiberboard laminate 3 is obtained. The cutting width at this time is
As will be described later, it is preferable that the width of the wood fiberboard laminate used in the frame base material 11 (FIG. 5) to be obtained is set to two width dimensions. (2) Formation of Composite Laminate (FIG. 2) As the veneer laminate 4 (hereinafter, referred to as LVL), a commonly used wooden veneer in which the fiber directions are laminated in parallel is used. Note that the veneer may be made of coniferous or hardwood, or a mixture of these. The LVL only needs to have the strength as a core material of the frame material, and therefore, the purpose can be sufficiently achieved with a commonly used LVL. In order to suppress the warpage of the LVL, an LVL having a cross band may be used. LV
The thickness of L is arbitrarily determined according to the width of the core material to be obtained.

意に決定されるが、通常は２〜２４ｍｍ程度とされる。Next, a wood fiber board 5 (hereinafter referred to as fiber board) is laminated on the back surface of the LVL 4 via an adhesive. As this fiberboard, MDF is suitably used similarly to the fiberboard used for the above-mentioned wood fiberboard laminate. The thickness of the fiberboard is arbitrarily determined according to the width of the core material to be obtained, but is usually about 2 to 24 mm.

基礎部８を形成する。After the LVL and the fiberboard are laminated via an adhesive, and heated and pressed by a press or the like to form a composite laminate 6,
The composite laminate 7 is obtained by cutting this into an arbitrary width in the longitudinal direction and in accordance with the thickness dimension of the wood fiber board laminate 3 (thickness dimension of a core base portion described later). (3) Formation of core base (FIG. 3) One wood fiber board laminate 3 obtained as described above is sandwiched between two composite laminates 7, 7 and the longitudinal direction of these laminates Are made parallel, and the front and back surfaces of the wood fiber board laminate 3 are vertically butted against the surface veneers of the LVLs 4 and 4 of the composite laminates 7 and 7, thereby forming the core material base portion 8.

表面が突き合わされる。In other words, when the core material is viewed as a cross section cut along a plane perpendicular to the longitudinal direction, the LVLs 4 and 4 of each of the composite laminates 7 and 7 are disposed on both side laminate surfaces of the wood fiberboard laminate 3. The surfaces are matched.

は接着剤が浸透していない滑らかな面であるため接着を
短時間で容易に行うことができる。The reason for such a match is as follows. That is, when the laminated surfaces of the laminate are bonded together, the laminated surfaces have irregularities, so that the bonding area is reduced and the bonding strength is reduced. In addition, the adhesive used to form the laminate exists on the lamination surface, which inhibits penetration of the adhesive used when bonding the lamination surfaces, and causes poor adhesion and time-consuming adhesion. There is a problem that. On the other hand, in the case of the above-mentioned abutting mode adopted by the present invention, in one of the laminates (composite laminate), the surface single veneer of the LVL serves as a laminate surface (adhesion surface), so that a sufficient adhesion area is provided. The surface of the veneer veneer is a smooth surface on which the adhesive has not penetrated, so that bonding can be easily performed in a short time.

May be performed at the same time as the formation.

ているＬＶＬを用いることができ、コスト面での有利性
が大きい。The composite laminates 7, 7 are obtained by cutting into a width dimension corresponding to the thickness of the wood fiberboard laminate 3, and this cut surface is a surface orthogonal to the single-layer laminate direction of the LVL4. Therefore, it is not necessary to strictly define the thickness of the LVL used to form the composite laminate. Therefore, a commercially available LVL can be used, and the cost advantage is great.

得られるようにしたものである。詳しくは後述する。Further, the reason why the composite laminates 7 and 7 are arranged on both sides of the wood fiber board laminate 3 is that the core material is later cut into two equal parts in the short direction so that two frame bases are simultaneously formed. The material was obtained. Details will be described later.

の板厚として用いられる。It is conceivable that the fiberboards 5, 5 of the composite laminates 7, 7 are abutted against the lamination surfaces on both sides of the wood fiberboard laminate 3, but in this case, the LVL4 , 4 are located, the surface smoothness is poor and the adhesive strength with the decorative sheet is insufficient, and the dimensional change due to the absorption and release of moisture is extremely large in the direction perpendicular to the fiber direction. Therefore, the decorative sheet is likely to be cracked or torn. (4) Formation of the core material (FIG. 4) The fiberboards 9 and
The core material 10 is formed by laminating 9 and heating and pressing with a press machine or the like. As this fiberboard, MDF is suitably used similarly to the fiberboard used for the wood fiberboard laminate and the composite laminate, and generally has a thickness of about 2 to 12 mm.

点がある。As described above, at this time, the bonding of the wood fiberboard composite 3 and the composite laminates 7, 7 may be performed at the same time, thereby shortening the manufacturing process. In this case, in the above-described step of forming the core material base portion 8, the composite laminates 7,
The LVLs 4 and 4 of No. 7 are abutted only by an adhesive, and the heating and pressing by a press machine is not performed. The core material 10 is formed by laminating 9 and pressing from both front and back surfaces and left and right sides. (5) Formation of frame base material (FIGS. 4 and 5) The core material 10 obtained as described above is cut along the longitudinal direction so as to be bisected in the lateral direction (cut surface in FIG. 4). X), two frame bases 11, 11 are obtained at the same time. As described above, the wood fiberboard composite 3 is approximately two times the width of the wood fiberboard composite 3 ′ in the frame base material 11 (strictly speaking, the wood fiberboard composite 3 ′).
(The dimension obtained by adding the thickness of the blade of the cutting machine to twice the width of the cutting machine).
By cutting at the same time, two frame base materials can be obtained at the same time, and not only is the production efficiency high, but also the advantage that a stable quality frame material can be obtained compared to the case where the frame base material is manufactured alone. is there.

The cutting may be performed within the thickness range of the fiber board 5 of the composite laminate 7 arranged outside the first laminate 1 (along the cutting plane Y, Y in FIG. 4). Thereby, the width of the frame base material 11 can be adjusted to the specified size. In addition, the outer surface of the fiberboard 5 is pressed at the time of forming the core material base portion 8 and the core material 10 (particularly, the joining of the wood fiberboard composite 3 and the composite laminates 7, 7 and the fiber The plates 9 and 9 are joined together in a single pressing step to form the core material 10, which is likely to be damaged by pressing in the left-right direction. Further, after the core material 10 is obtained, it is transferred to a cutting machine by a belt conveyor or the like. Since it is easy to be damaged when it moves, cutting this portion gives the frame base material 11 a smooth side surface, thereby increasing the product value. (6) Formation of the frame material (FIG. 6) The side surface of the wooden fiberboard laminate 3 ′ located on the inner peripheral side of the obtained frame base material 11 is cut to form the nesting edge 12 and the mirror plate fitting groove 13.
