Claims
- 1. A method of shaping glass sheets comprising the steps of:
- heating said glass sheets;
- transporting said glass sheets at a first level in a horizontal position into a curving station;
- curving said glass sheets by way of curving tools in said curving station;
- moving said glass sheets, during said curving step, to a second level which is substantially higher than said first level;
- continuously heating said curving station by way of heating means disposed between said first and second levels; and
- conveying said glass sheets at said second level to a cooling or quenching station such that a cold air current which enters said curving station at said second level is heated and deflected by heat from said heating means so as to not affect glass sheets at said first level.
- 2. A production line for producing curved glass sheets comprising:
- a furnace for heating the glass sheets;
- a curving station comprising means for curving the glass sheets;
- means for conveying said glass sheets, at a first level and in a horizontal position, from said furnace to said curving station;
- means, in said curving station, for moving said glass sheets from said first level to a second level of said curving station which is substantially higher than said first level;
- means for heating said curving station, said curving station heating means being disposed in said curving station between said first and second levels;
- a cooling station for cooling said glass sheets; and
- means for conveying, at said second level, said glass sheets from said curving station to said cooling station, wherein a cold air current which enters said curving station at said second level is heated and deflected by heat from said heating means so as to not affect glass sheets at said first level.
- 3. An apparatus for curving a sheet of glass for producing automobile panes or the like, comprising:
- a heating furnace for heating the glass sheet;
- a curving station comprising a curving mold and a suction chest, said suction chest comprising a stationary vertical duct and a skirt which is integral with said curving mold, said skirt and integral curving mold being movable as a unit with respect to said stationary duct;
- a conveying means for transporting the glass sheet from the furnace to the curving station; and
- a receiving carriage for receiving a glass sheet which has been released from said curving mold and transporting said glass sheet from said curving station, wherein said skirt and integral curving mold are movable as a unit with respect to said stationary duct for permitting said receiving carriage to be introduced therebetween for receiving the glass sheet released by the curving mold.
- 4. Apparatus according to claim 3, comprising centering means for centering the glass sheet, said duct serving as a support for the centering means.
- 5. Apparatus according to claim 3, further comprising a bearing means for limiting ascending and descending movements of the skirt with respect to the duct, said bearing means being positioned on the duct for contacting against the skirt when the skirt descends toward the duct.
- 6. Apparatus according to claim 3, wherein said conveying means transports the glass sheet from the furnace to the curving station at a first level, and said receiving carriage transports said glass sheet from said curving station at a second level which is different than said first level.
