Abstract

PURPOSE: To enable mission-tile-shaped roof members to be formed in continuous stages by bending a flat plate material in such a manner that the surface of a mission tile shape having the curved edges of the mission-tile-shaped parts assume a concave-curved surface and continuously working this in the longitudinal direction of the plate material.
CONSTITUTION: A copper plate 9 as a plate material having a required broadside length is placed on a lower die 10, and an upper die 11 is pressed in the arrow A direction, so that the copper plate 9 is bent in correspondence to the dies 10, 11. In this case, the lower die has an end face 15 of a convex-curved shaped corresponding to the shape of one of the unit parts 13, 13... of a mission tile shape of a roof member 12 and corresponding to its leading edge 14, and a top surface 17 of a concave-curved shape corresponding to a surface 16. Thence, the side edges are bent to form risers 18. In this case, the corner angle parts 19 of the leading edge 14 and the risers 18 are formed to an acute angle and show a beautiful appearance. The abovementioned working is performed to the copper plate 9 at every prescribed interval in the longitudinal direction thereof, whereby the roof member 12 of a prescribed length is formed.
