Description of the Related Art For example, as a metal plate used for an outer wall material or an inner wall material of a building, a grooved or tiled pattern (hereinafter referred to as a brick or tiled pattern) is formed by embossing groove joints vertically and horizontally by pressing or rolling. Some tiles are called "tiles." In recent years, there has been a tendency for a sense of design and three-dimensional appearance to be emphasized as wall materials, and bricks or tiled patterns that are full of design and three-dimensional appearance by deeply processing vertical and horizontal groove joints have been demanded.

ことができなかった。However, according to the press working of embossing by pressing a metal plate between a pair of dies having irregularities opposite to each other, the vertical and horizontal groove joints are compared to meet the above demand. Although deep embossing can be performed, when a long metal plate is pressed, there are disadvantages in that the number of processing steps is extremely large and the manufacturing cost is high. On the other hand, according to the roll processing of embossing by passing a metal plate between a pair of embossing rolls, it is possible to continuously process a long metal plate and to reduce the manufacturing cost. Could not emboss.

ができなかった。For example, in continuously processing siding with a brick or tile-patterned pattern with a roll, first, a band-shaped metal plate is passed between a pair of embossing rolls to emboss the groove joints vertically and horizontally, so that the vertical and horizontal groove joints are formed. Apply a brick or tile pattern to be enclosed. Then, by bending both ends of the metal plate by roll homing or the like, an engagement recess for joining the ends of the siding to one end of the metal plate is provided at the other end of the metal plate. An engaging projection having a fitting shape is formed. At this time, if the vertical and horizontal groove joints are deeply embossed, the deep vertical and horizontal groove joints that are applied during the bending process of the engaging uneven portion will be an obstacle to the bending process, making the bending process difficult, so only the shallow vertical and horizontal groove joints are embossed. I couldn't.

て平坦部に歪みが発生しやすいのである。[0005] As a countermeasure, by flattening both ends of the metal plate at the time of roll embossing of the vertical and horizontal groove joints, the flat portion is bent by roll homing or the like after the embossing. It is conceivable to form engagement concave and convex portions at both ends of the metal plate. However, such a flat portion left during the roll embossing of the metal plate is wavy or the end of the flat portion is easily warped up and down, and the metal plate meanders in a direction perpendicular to the flow direction. This also makes it difficult to bend the engaging concave and convex portions. Distortion such as warping or waving occurs in the flat part because the vertical groove joints tend to shrink in the longitudinal direction by embossing the vertical groove joints in the width direction orthogonal to the longitudinal direction of the metal plate. As a result, the longitudinal length of the vertical and horizontal groove joint region becomes shorter than the longitudinal length of the flat portion having no unevenness, and the flat portion is likely to be distorted due to this difference in length.

Another object of the present invention is to provide an embossed metal plate which can facilitate bending at both ends of the metal plate and can be manufactured at low cost by continuous processing.

The flat portion 9 tends to be distorted, but this distortion is corrected by embossing a large number of small irregularities 10 on the ear portion 11 and adjusting the length in the longitudinal direction of the vertical and horizontal groove joints 5.6. Because of the absorption, the flatness of the flat portion 9 can be maintained. By maintaining the flatness of the flat portion 9, the lateral groove joint 6 and the engaging uneven portions 17 and 20 can be easily bent.

The engaging projections 20 of the other metal plate 1 are joined by engaging and disengaging the joints. With this joining, the horizontal groove joint forming part 16 of the one metal plate 1 and the horizontal groove joint forming of the other metal plate 1 are connected. The other groove pieces 19 are combined with each other to form a horizontal groove joint 6 having no uneven pattern similar to the other horizontal groove joint 6.
In this case, if the flat portion 9 is formed up to the inclined wall portion 23 connecting the respective pieces 16 and 19 and the engaging uneven portions 17 and 20, the inclined wall portion is formed when the metal plates 1.1 are joined together. Part 2
