The original plate formed by this papermaking process is the original plate (the papermaking direction in which the hand is facing)
However, the fiber direction of the cut roof tile is parallel to the front edge of the roof tile. When roof tiles are placed on a roof, the direction of the fibers of the roof tile is perpendicular to the direction of the eave ridge of the roof, making it more likely to crack when stepped on. There was a problem that it was difficult to break through.

。[Disclosure of the Invention] In the method for manufacturing a roof tile of the present invention, each bead of the size of four roof tiles 2 is added to a base plate 1 in the form of a green sheet, which is formed so that the fiber direction is oriented in the direction of the hand force. The cut piece plate 3 is then pressed to give a pattern and cut, the orientation of the cut piece plate 3 is reversed by 90°, and the edge perpendicular to the fiber direction is trimmed by punching to form edge irregularities 4. , the piece plate 3 is cut in a cross shape to form four roof tiles 2 having the edge unevenness 4 as the front jl#, and by configuring as described above, the conventional example This solves the shortcomings of In other words, by manufacturing as described above, it is possible to manufacture the roof tile 2 whose front edge is the edge perpendicular to the fiber direction, and the fiber direction of the roof tile 2 is directed toward the eave ridge when it is installed on the roof. Becomes stronger against cracks,
Furthermore, by having the edge unevenness 4 on the edge, the appearance can be changed and the appearance can be improved.Furthermore, the pattern placed on the original plate 1 for each piece can be changed, and the edge edge formed by punching on each piece plate 3 can be changed. By changing the shape of the unevenness 4, it is now possible to obtain a wide variety of roof tiles 2.

る。The original plate 1 shown in FIG. 1(a) is in the form of a green sheet formed by paper-making a slurry containing fibers, and is in the form of an elongated rectangle. The wL fiber direction of the original plate 1 (in the direction of the arrow) is oriented in the papermaking direction, and is oriented in the longitudinal direction of the original plate 1. This original plate 1 is pressed into pieces having an area equivalent to four roof tiles 2, a pattern is imparted to the original plate 1, and then cut. In the case of this embodiment, three piece plates 3 are formed by pressing the a, opening and opening portions of one original plate 1, respectively. At this time, different patterns may be used for pressing the A, mouth, and C parts, and the patterns of the A, mouth, and C parts may be changed. When cutting the piece plate 3 with a press, there is a notch on the edge on the center line of the piece plate 3! 5 is also provided. This piece plate 3 is dried as necessary, and then the piece plate 3 is rotated at an angle of 90° as shown in FIG. 1(b).
This is reversed so that the fiber direction is perpendicular to the original plate 1.

す（なって、凍害を受けやすくなる。The edge of the piece plate 3 perpendicular to the fiber direction is shown in FIG.
As shown in e), edge unevenness 4 is formed by trimming by punching, and a through hole 6 is formed in the center of the piece plate 3.
is punched out. Here, the part indicated by hatching is the punched part. At this time, the punching can be done for every 6 pieces of P6 board 3 which are small in size, so the punching die can be small. Also, if the edge unevenness 4 is formed by punching, , the frost damage resistance is improved.In other words, if the green sheet is pressed to form a pattern and cut at the same time, the water that seeps out during the press will run between the eyebrows, making it easier for the layers to separate (which can lead to frost damage). It becomes easier to receive.
原板１から切断した各ピース板３は夫々別々のラインに

屋根瓦２を並べて葺かれる。After punching, the piece board 3 is coated with a 70-coater, spray, etc., dried, and cut into a cross shape.
Two roof tiles 2 are formed. As shown in FIGS. 2(a) and 2(b), the front edge of the obtained roof tile 2 has edge irregularities 4 of various shapes, and the fiber direction is perpendicular to the front edge. The roof tiles 2 are laid on the roof in sequence from the eaves side to the line side, and the roof tiles 2 are laid side by side as shown by the imaginary lines in FIGS. 2(a) and 2(b).
なお本発明の屋根瓦の製造方法は屋根瓦のように葺く外
装材のような建築用板の製造にも応用できる。The method for producing roof tiles of the present invention can also be applied to the production of architectural boards such as exterior materials for roof tiles.

It is possible to obtain a roof tile that is resistant to stepping cracks, and also to have a roof tile that has unevenness on the front edge, so it is possible to obtain a roof tile that has a different appearance. It is possible to obtain a wide variety of roof tiles by changing the pattern placed on each piece, and by changing the edge irregularities formed by punching each piece board.
