本発明はセメント板、石綿セメント板、石膏混入セメン
ト板などの凹溝を有する無機質板の製造法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an inorganic board having grooves, such as a cement board, an asbestos cement board, and a cement board mixed with gypsum.
従来の凹溝を有する無機質板の製造法は無機質スラリー
を抄造して無機質生坂を製造した後で所望の凹溝をやや
硬化した状態で型プレスにて押圧せしめて形成するのが
通常であった。The conventional manufacturing method for inorganic plates having grooves is to form an inorganic slurry to produce an inorganic raw slope, and then press the desired grooves with a mold press in a slightly hardened state. .
しかしながら、この凹溝をシャープに深みのあるように
形成すると無機質板特有のクラックが表面に現出してし
まうという欠点があった。本発明は以上の実情に鑑みて
なされたもので、その目的とするところは無機質スラリ

溝を有する無機質板の製造法にある。However, if the grooves are formed sharply and deeply, cracks peculiar to inorganic plates will appear on the surface. The present invention has been made in view of the above-mentioned circumstances, and its purpose is to form a first groove with a roller at the same time as sand-shaping an inorganic slurry, and then press a press so as to be in synchronization with the first groove. The present invention provides a method for manufacturing an inorganic plate having grooves, in which sharp and deep grooves can be imparted by pressing the plate to form second grooves and performing two-stage pressing.

るので押圧プレスの押圧力も少くてすむ。Then, pigment is supplied from a pigment supply tank 6 arranged on the upper right side of the partition plate 5. Furthermore, this inorganic slug I
J-4 is formed into paper by the suction force of the vacuum pump 2 to form an inorganic slurry layer 14, and this inorganic slurry layer 1
A color-bridging layer 15 is formed on top of the inorganic raw slope 1.
1 is formed. At this time, at the same time as the inorganic slurry 4 is made into paper, the first
A groove 16 is formed. Then, the inorganic raw slope 11 with the first groove 16 formed therein is cut by saw blades provided above the belt conveyors 8 and 9, and then transported to the press 12. Then, the second concave groove 16 is aligned with the first concave groove 16 of the inorganic raw slope 11 conveyed to the pressing press 12.
The groove 17 is pressed. Thereafter, the inorganic raw board 11 is carried out to a dryer 13 and dried to form an inorganic board. Therefore, unlike the conventional method in which the inorganic slurry is formed into a paper and then the desired grooves are pressed with a forming press, the inorganic slurry 11 is preliminarily formed in a hardened state using the rollers 7. Since the second groove 17 is formed by the divine pressure press 12 after forming the first groove 16, the pressing force of the pressure press can be reduced.

。Moreover, if pressed once in a slightly hardened state, cracks peculiar to the inorganic raw slope 11 will occur, but since two-stage pressing is performed, the first groove 16 whose volume has decreased is instantly pressed, thereby preventing cracks. I can do it. Moreover, the first groove 1
If the grooves 6 are formed deep, the second groove 17 can be easily molded without any cracks. As described above, the present invention produces an inorganic slurry and simultaneously produces an inorganic raw slurry.
