<p>The invention relates to a heat transfer method in a glass sheet bending furnace as well as to a bending furnace for carrying out the method. The furnace includes a top array of successive heating sections (2) and a bottom array of successive cooling sections (4). The glass sheets are placed upon bending moulds (6) supported by carrier wagons (5). Successive wagons (5) are advanced on an upper conveyor track (7a) from one heating section (2) to the next and, respectively, on a lower conveyor track (8a) from one cooling section (4) to the next. Heat is transferred from bent, hot glasses (HG) in cooling section (4) to non-bent, colder glasses (CG) in heating section (2) by means of sucking air from cooling section (4) and by blasting it into heating section (4). Air is blasted on either side of glass sheet (CG) contained in heating section (2) and further on either side of glass sheet (HG) contained in cooling section (4).</p> |
