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.

Process and apparatus for the bending of flat sheets of glass

Bending and tempering of a glass sheet is achieved in that the glass sheet is submitted to the tempering phase while still being placed, as in the forming phase, on a forming ring integral with a frame which holds the latter, in order to maintain the previously formed shape unaltered. Vertical upward and downward movement is achieved both in the forming zone and in the glass sheet discharge zone by means of a rotating coupling device which supports the frame with forming ring and the glass sheet placed thereupon. Means are provided for conveying the frame with integral forming ring in the horizontal direction from the forming zone to the subsequent tempering and discharge zones, and other overlying similar means are provided to return the frame and forming ring from the discharge zone to the forming zone. A passageway or chamber is formed in the upper nozzle section of the tempering zone, through which may pass the frame and forming ring, as well as their horizontal driving members during the return traverse.
