強度保持が難しい。Conventionally, rock wool-based mineral substrates, insulation boards mainly made of soft fibers, and magnesium carbonate-based substrates are all made from paper, and after the drying process, edge processing such as tongue processing is applied to the dry mat state. It is difficult to maintain the strength of the end face.

きな端面部強度の向上は望めない。On the other hand, in order to improve the edge strength of the aforementioned boards, measures such as increasing the specific gravity are sometimes taken, but this also has a limit to achieving the characteristics of a lightweight board, and it is not possible to increase the edge strength. There is no hope for improvement.

% of tenona waste was generated, and the material loss was large.
本発明はかかる従来の欠点を解消せんとするもので、以
下添付図に基づいて詳細に説明する。The present invention aims to eliminate such conventional drawbacks, and will be described in detail below with reference to the accompanying drawings.

、しかるのちに上型４を同様に圧締して中央部３を加圧
成形する。First, this paper-made board 1 is placed in a wet mat state as shown in FIG. The tongue-shaped portion 5 is lowered and pressed using a hydraulic device, an air cylinder, etc., and the end portions of the papermaking plate 1 are press-formed.Then, the upper die 4 is similarly pressed and the central portion 3 is pressed.

、スペーサ７を取り除いた後次工程にベルト等で送る。After holding the pressure for an arbitrary period of time, the pressure is first removed from the upper die 4, and then the pressure is removed from the rabbeted portion 5 to complete the molding process.After the spacer 7 is removed, the product is sent to the next process using a belt or the like.
尚除圧は上型４、さね加工部５を同時に行なっても良い
。Incidentally, the pressure may be removed from the upper die 4 and the tongue processing portion 5 at the same time.

時にねらうことができる。Furthermore, by operating the suction box 9 attached as an accessory device at the same time as the start of molding, it is possible to simultaneously aim for the effects of lowering the moisture content of the paper sheet after molding and improving mold release.
また上記成形圧力としては１０〜１００ Ｋ９／ｃａ、
保圧時間は１０〜３００秒が適当である。In addition, the above molding pressure is 10 to 100 K9/ca,
The appropriate pressure holding time is 10 to 300 seconds.

にさね加工を施すに当っても切削ロスが軽減できるもの
である。In the present invention, as described above, the edges of the sheet-formed board are press-formed in a wet mat state, so edge processing can be performed on the edges of the obtained substrate without cutting the structure. This prevents deterioration of the strength of the edges, does not impair the lightweight properties even in the case of lightweight plates, and can reduce cutting loss when rabbeting the edges. .

When male grooves B and female grooves C are applied to the ends of , the characteristics of the center portion X and the end portion Y shown by diagonal lines in FIG. 2 are compared as shown in the table below.

である。In addition, when applying similar processing, in the conventional case, the area shown with diagonal lines in Figure 3 would be a loss due to cutting due to processing the dry mat, and this would be 8%, but in the case of the present invention, it is the same. This process requires only a small amount of cutting (loss rate: 4.6) as indicated by diagonal lines in Figure a, reducing losses.

層減少すると共に二次加工が簡略化されるものである。In addition, in the present invention, the edges are first pressure-formed and then the center portion is pressure-formed, so it is possible to achieve accurate perpendicularity when pressing the edges, and cutting loss is reduced. This further reduces the amount and simplifies secondary processing.
即ち、端部と中央部の加工を一段成形にて同時に行なう

げ部りを設けておく必要がある。That is, if the end portions and the center portion are processed simultaneously by one-stage molding, it is necessary to provide a relief portion at the boundary between the center portion 3 and the end portion 2, as shown in FIG.
