ABSTRACT:
A heated and softened glass sheet is put on a bending surface of a frame unit to be preliminarily bent by gravity before the glass sheet is pressed by an upper mold and the frame unit. There are steps for using a certain means for controlling an amount of preliminary bending to control deformation of the glass sheet caused by the preliminary bending; and pressing the preliminarily bent glass sheet by the upper mold and the frame unit.
