As shown in FIG. 1, the entirety of one member was formed so as to pass through between the corrugated rolls (b) and (c) which mesh and rotate.
As shown in FIG. 2, when a corrugated sheet having a wave width of 80 mm and a wave height of 20 mm is formed using a flat plate, the left and right wave peaks (d) and (e) are obtained.
11 mm, which is the difference between the in-plane dimension 91 mm and the wave width between the top (f) and the top (g), needs to extend about 14%. The elongation of the cold rolled steel sheet is 4 in terms of tensile strength.
0% or more, and no break occurs in the corrugated sheet even at the final stage of molding.

When the whole corrugated sheet of 13 peaks of 20 mm in height and 20 mm in height is simultaneously pressed by the upper mold (A) and the lower mold (B) by unconstrained outer periphery, the left and right outer sides of the flat plate (1) are initially formed. The molding proceeds while the raw material is drawn in from the inside, but when it comes close to the final stage of pressing, as shown in FIG. 4, the tops of the wave ridges (a) and (b) of the upper and lower dies (A) and (B) (C) The upper surface (1h) and the lower surface (1i) of the flat plate (1) formed in a corrugated shape are in sliding contact with each other, and the constraint points (X) are the left and right outer edges of the flat plate (1). In addition, the molding was performed in a state close to the state constrained at the constraint point (Y), and as this molding proceeded, a break occurred at the center of the flat plate (1).
