Mould assembly for bending difficult bending shapes in a glass sheet |
摘要 |
The invention relates to a method for bending difficult bending shapes such as an S-shape in a glass sheet. The downward bending of an outline-mould supported, heated glass sheet is assisted by a non-engaging lower partial surface mould used for blowing to a bending line (BL) or its vicinity a gas having a temperature at least equal to that of glass, the gas serving simultaneously as a glass carrier preventing its falling or excessive downward sagging. Blasting orifices in the shaping surface are adapted to concentrate heating on the most problematic areas of a bending line.
