The invention relates to a device for gravity bending a glass sheet, which includes a longitudinal grinder, including two longitudinal grinding mountings, and a finishing frame, including two lateral finishing mountings and two longitudinal finishing mountings. Said mountings form molding tracks. The distance between the centers of the longitudinal finishing mountings is shorter than the distance between the centers of the lateral finishing mountings. The grinder or the finishing frame is vertically movable relative to the other during bending, such as to pass from a rough bending configuration to a final bending configuration. Said device is characterized in that, in the rough bending configuration, the molding tracks of the longitudinal grinding mountings are higher than the molding tracks of the longitudinal finishing mountings. Said device is further characterized in that, in the final bending configuration, the molding tracks of the longitudinal finishing mountings are higher than the molding tracks of the longitudinal grinding mountings and in that the molding tracks of the lateral finishing mountings are the only molding tracks under the side edges of the glass in the rough bending configuration and in the final bending configuration. The invention also relates to the bending method using the device according to the invention. The invention particularly makes it possible to produce a glass panel having an enamel layer that is less wide on the side edges than on the longitudinal edges. |
