Tempering section of a flat glass tempering machine saves energy and reduces peak power by shutting an area of tempering section in the areas where there is no glass. The tempering section is multipurpose so that the first part can be used as a high pressure section for tempering thin glasses, latter section being after the cooling section. Further, the high pressure section can use air produced by a blower and/or compressor.;The tempering section includes rollers transporting glass, upper and lower pressure chambers, nozzle boxes attached to them, nozzle covers with nozzles and necessary shutting devices and internal walls. |

1. A tempering section of a flat glass tempering furnace, which tempering section comprises rollers for oscillating the glass to be tempered, at least one pressure chamber where tempering air is guided, nozzle boxes parallel to the rollers and attached to the pressure chamber and nozzles at the ends of the nozzle boxes through which nozzles air is blown against the glass, whereby at least some of the nozzle boxes are provided with dividing walls each dividing wall separating an end of the nozzle box from the center of the nozzle box, the tempering section further comprising shutting devices for preventing the tempering air from entering into the ends of the nozzle boxes thereby reducing the width of the tempering area of the tempering section. |
