ていた。2. Description of the Related Art Slate roofing materials such as asbestos cement tiles have a relatively small thickness and lack a three-dimensional appearance of the roof surface when the roof is laid. For this reason, there are cases where slits B, B are provided on the left and right ends of the roofing material A as shown in FIG. 5 so that the surface of the roofing material has a pattern pattern to change the roof surface expression. In this case, a conventional slate roofing material A is manufactured by pressing a strip-shaped molded product obtained by extruding an inorganic kneaded material after natural drying to produce a predetermined flat roofing material original sheet, and then slitting the same with a die. B, B were carved.

められている現在にそぐわない欠点があった。However, in the above-mentioned conventional manufacturing method, the original plate is cut at a constant pressure while the mold shape is constant. Since the slit shape is constant and sharp, the roof surface expression obtained by roofing the roofing material A is the same in every building, and there is a drawback that is not suitable for the present day when individuality is required.

When forming a slit on the original plate from the leading end of the original plate toward the rear end of the original plate by a cutting blade, the cutting pressure of the cutting blade is changed for each original plate, and the cutting pressure corresponding to the slit is also made uneven to perform cutting. It is characterized by the following.

されている。[0007] The method for producing a slate roofing material of the present invention comprises:
For example, a method for manufacturing a flat roof material such as an asbestos cement tile, in which an extruded product of an inorganic kneaded material is naturally dried and pressed to produce flat roof material original plates 1A and 2B having a predetermined shape, In the first embodiment, when the slits are punched out by the cutting blade to form the slate roofing materials 1 and 2, in the first embodiment, each of the original roofing materials 1A or a plurality of The cutting pressure of the cutting blade 5 is changed every time, and the slits 6 and 6 are punched out. In the second embodiment, the cutting blade 7 is composed of a plurality of divided pieces 7a, 7b, 7c and these divided pieces 7a, 7b, 7c. The slits 8 are punched out with irregular cutting pressures.

個々の屋根材１，２の強度等の物性には影響しない。According to the first embodiment, since the slit 6 is formed by changing the cutting pressure of the cutting blade 5, the conventional sharp slit B as shown in FIG. Of course, it is possible to manufacture a roofing material having a low cutting pressure, and intentionally cause chipping by lowering the cutting pressure, and the slit 6 having an irregular shape as shown in FIG. Therefore, various slit shapes can be obtained depending on the conditions. Also, in the second embodiment, by making the cutting pressure of the cutting blade divided pieces 7a, 7b, 7c uneven, the internal shape of the single slit 8 varies depending on the portion as shown in FIG. Thus, various slit shapes can be obtained by these pressure changes.
Therefore, it is possible to make the slit shape of each roof material irregular. The method of the present invention is applied to the cutting blade 5,
Since the processing is performed by changing the cutting pressure of 7, the physical properties such as the strength of the individual roofing materials 1 and 2 as products are not affected.
