摘要： Process for bending glass sheets, particularly in pairs, in which the glass sheets undergo a pre-bending under the effect of gravity in a horizontal position on a concave annular bending ring (3) whose profile corresponds to the desired final profile of the glass sheets, until the edges of the glass plates are applied entirely to the bending block (3). A monolithic convex bending block (31) is then applied over the whole surface and acts from above on the glass sheets (21). The inner part of the sheets then undergoes supplementary bending which gives it the desired final shape, the glass sheets being pressed by suction, against the monolithic convex bending block, at the edge of the monolithic convex bending block (11).

摘要： 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.
