ABSTRACT:
A method and device for the bending, on a frame, at least one glass sheet by gravity includes two bending steps. The glass sheets are first supported at their periphery along a first peripheral line by a rough bending device during the first step and along a second peripheral line by a definitive bending device during the second step. Transfer of the glass sheets from the first peripheral line to the second peripheral line is performed by positively and continuously regulating a position of at least one of the rough and definitive bending devices in reaction to forces generated on the at least one of the rough and definitive bending devices by contact with the glass sheet.
