Abstract
The invention relates to bending of glass plates moving in a horizontal position, under the effect of their own weight, with a device comprising a shaping bed made of rotating shaping elements whose surfaces in contact with the glass plates, as they advance, define increasingly curved generatrices, these shaping elements being carried by a frame that can be inclined by pivoting around a transverse axis located at its upstream end. The frame is mounted on pivoting axes (XX', YY', ZZ') that are adjustable in height. Particular zones of the glass plates can be kept at a constant level during bending, which improves the optical quality of the glass plates thus bent.
