る。Since the flat plate-shaped extrusion-molded product 1 is extrusion-molded from the extrusion-molding machine 4, it can be made simpler and smoother than extrusion of a modified cross-section. By imparting a pattern to the flat-plate extruded product 1 with the embossing roll 2, the extruded product 1 can be easily conveyed and a pattern can be imparted. An extrusion-molded product having an irregular cross section is formed by forming a bending groove 5 on the back surface of the extrusion-molded product 1, placing it on a tray 6 having a predetermined shape, bending it by the bending groove 5 and then placing the extrusion-molded product 1 along the tray 6. 1 can be molded.

ことにより断面Ｌ字形の押出成形品１が得られる。EXAMPLE An extrusion molding machine 4 is one for extruding a cement-based material, and a flat plate-shaped extrusion molding product 1 is continuously extruded from an extrusion port of the extrusion molding machine 4. As shown in FIG. 2, a conveyor 7 made of a flat conveyor is arranged in front of the extrusion port of the extrusion molding machine 4, and an embossing roll 2 which is rotationally driven is arranged above the conveyor 7. . When the extrusion-molded product 1 of the cement-based material is extruded from the extrusion-molding machine 4, the cement-based material is conveyed in a soft state by the conveyor 7, and the embossing roll 2 is formed on the upper surface of the extrusion-molded product 1 as shown in FIG. Thus, the uneven pattern 3 is provided. After the concavo-convex pattern 3 is provided, an inverted V-shaped concave groove 5 for folding is formed on the back surface of the extruded product 1 to be conveyed by a knife or the like.
It is formed continuously as shown in FIG. In the case of this embodiment, a relatively wide folding groove 5 is formed at the center in the width direction. The extrusion-molded product 1 on which the bending groove 5 is formed is cut into an appropriate size, and as shown in FIG.
The extrusion-molded product 1 having an L-shaped cross section is obtained by placing it on a tray 6 having a letter-shape, bending it with a concave groove 5 for bending to conform to the shape of the tray 6, and curing it in this state.
