Title of Invention | METHOD AND APPARATUS FOR PRODUCING A BENT AND TEMPERED THIN GLASS SHEET |
---|---|
Abstract | The invention relates to the press bending anti tempering of glass sheets, especially for use as .glazings in vehicles. When the press benliing system (13) is not located in a heated environment such as a furnace (12), it is important to maintain the glass sheets (11) at a sufficiently high temperature for an adequate degree of temper to be achieved on quenching the sheet. The present invention provides a method of bending and tempering a thin glass sheet (11) comprising pressing the substantially horizontal sheet between moulds (61,62) having opposed complementary shaping surfaces (110,130), at least one of said surfaces being heated, and subsequently quenching the surfaces of the sheet characterised in that the heated shaping surface (110) is maintained at a temperature in the range from 200QC to 350QC. |
