マット２上に載置する。However, when the asbestos cement board 1, which has been made into an appropriate size by the paper making machine 6, is pressed, the asbestos mixture flows, and the moisture content is in the range of 25% to 40%, especially when the asbestos mixture flows too much and does not flow out of the formwork. Place it on mat 2 at around 30%.

。At this time, the mat 2 is depressed downward by the punching blade 7 protruding from the lower part of the punching die 3 as shown in FIG. Corresponding to the depression, the punching blade 7 is plastically deformed along the vertical blade surface, and as shown in FIG. 3, a protrusion 6 is formed on the lower surface of the end of the punched asbestos roofing sheet 5 material.
尚マット２は０、３ ｍ１以上の厚さに形成しておけば
打抜き刃７によって切断されない。Note that if the mat 2 is formed to a thickness of 0.3 m or more, it will not be cut by the punching blade 7.

して量産ができるという効果を奏する。In the present invention, an uncured asbestos cement board just before hardening is placed on a flexible mat, and the unhardened asbestos cement board is punched from above using a punching press having a punching die. A part of the mat is depressed downward along the punching blade, and the cut end of the uncured asbestos cement board is plastically deformed along the depression, resulting in a protrusion on the back side of the cut end of the asbestos cement roofing material. It is possible to form a desired asbestos cement roofing sheet that has a solid appearance after construction and is less likely to infiltrate with rainwater. Moreover, since the protrusion is formed at the same time as the punching process of the asbestos cement roofing sheet material, This has the advantage that it can be mass-produced compared to casting.
