Title: Apparatus for bending glass sheets.
IPC: C03B35/14
Filed: 1984-10-19
Abstract: An apparatus disclosed for use in bending heated sheets of glass transported generally horizontally on a conveyor within a furnace heating chamber includes a holder and a counterbalanced bending member, both of which are located above the conveyor in a spaced relationship such that a heated sheet of glass can be transported under the holder. The holder includes a curved, downwardly facing surface with spaced openings in which vacuum is drawn to receive the glass sheet from the conveyor. Gas, such as air, is blown upwardly from below the conveyor against the heated sheet of glass such that the sheet is moved upwardly and into engagement with the curved surface of the holder. The bending member then moves downwardly below the holder surface and thereafter upwardly against the heated sheet of glass to provide bending thereof to the curved shape of the holder surface. The bending member then moves back to its home position above the holder surface. A carrier mold ring moves under the supported glass and the vacuum is then terminated so the glass drops onto the ring and bends under the bias of gravity in a manner that allows the glass to be further bent. Subsequently, the mold ring is moved from the furnace to a quench unit that tempers the glass.
