ABSTRACT:
In a horizontal plant for the production of curved and tempered sheets of glass, an apparatus for the bending of the sheets of glass is provided. Conveyor rollers are provided that are downwardly mobile at opposite ends thereof, one with respect to the other. The conveyor rollers are situated between male and female bending moulds, thus permitting the production of sheets of glass having complex forms, reduced thicknesses and notable dimensions. The bending process makes use of the possibility of inclining the rollers to place the sheet of heated glass on the female mould.
