Abstract
A device for the gravity-bending of a glass sheet, includes a longitudinal roughing mold including two longitudinal roughing supports, and a finishing frame including two lateral finishing supports and two longitudinal finishing supports, the supports forming shaping rails. The distance between middles of the longitudinal finishing supports is shorter than that between middles of the lateral finishing supports. The roughing mold and finishing frame are movable vertically relative to each other during bending to switch from a rough-bending to a final-bending configuration. In the rough-bending configuration, the shaping rails of the longitudinal roughing supports are higher up than those of the longitudinal finishing support. In the final-bending configuration, the shaping rails of the longitudinal finishing supports are higher up than those of the longitudinal roughing supports. The shaping rails of the lateral finishing supports are the only ones under lateral edges of the glass in the roughing and final-bending configurations.
