Abstract

PURPOSE: To prevent the cracking and waving phenomena of the flange part, and to improve the yield, by placing both ends of flanged sheet material upon the holding member so as to support the lower face with the correcting member, and by pressing from upside with the pushing member for forming the sheet material into a curved shape.
CONSTITUTION: The flanged sheet material 20 is put, with its flanged part 20b down, upon a pair of rollers 16. Next, while the lower side of the lining part 20a is being supported by the correcting member 17, the upper side 20c is pressed by a semicylindrical pressing member 18 having a circular arc surface. Hereby, the lining part 20a of the sheet material 20, while its lower side is being supported by the correcting member 17, is pressed and bent into a curved shape by the pressing member 18.
