The difference of this example from that of FIG. 3 is that the edge fold 2 is formed only on one edge of the strip-shaped metal plate 7, and then the edge fold 2 is formed. A large number of louvers 1 are cut and raised by a pair of fin forming rolls, and the openings of the louvers 1 are directed toward the edge folding 2 side. Also in this case, the presence of the edge folds 2 increases the rigidity of the fins, so that it is possible to prevent the corrugated fins 8 from being deformed as shown in FIG. 6B. Next, FIG. 5 is an example in which an edge fold 3 is formed on the edge portion on the opposite side to that of FIG. In this case as well, the presence of the edge folds 3 increases the rigidity of the fins as a whole, and it is possible to prevent deformation of the corrugated fins 8 as a whole after molding.
