Abstract
The invention relates to a method and apparatus for bending and tempering a glass sheet. A heated glass sheet is carried from a furnace onto a conveyor in a bending and tempering section, said conveyor comprising a plurality of individual conveyors in the form of an endless belt or caterpillar track. The conveyor serves as a bending mould, a transfer conveyor and a tempering support. A glass sheet is bent by pivoting the body structures (6) of individual conveyors relative to each other in a manner that the lower runs of individual conveyors pull away from each other in lateral direction while, at the same time, the upper conveyor runs are bending to an arched shape. The chilling blast for bent glass is effected through openings (17, 18) in the halted conveyor.
