Abstract
The invention relates to a method and apparatus for bending a glass sheet. A glass sheet (5) is supported on a bending mould (6) in a heating furnace and heated close to a softening temperature by means of a heating field generated by heating elements (4). Glass sheet (5) is placed adjacent to the heating field whose energy distribution is adjusted as desired. Glass sheet (5) is controllably pulled away from the heating field as the glass heats up and begins to bend.
