ABSTRACT:
A blow box for thermal tempering of panes of glass is disclosed. To temper different sizes of glass, the air supply to selected blow tubes or blow tube groups in a blow box having a blow nozzle field disposed to handle relatively large panes of glass is blocked in the edge areas of the blow box. In this manner, the blow nozzle field supplied with forced air is adapted to the shape and size of the glass pane to be tempered. The adaptation of the blow nozzle field to the shape and size of the glass panes takes place, for example, with the aid of a template-like slide block having an opening corresponding to the glass pane, which slide block is arranged inside the air distributing box immediately in front of the front plate provided with the nozzle pipelets and which can be exchanged for a different slide block.
