Abstract

Device for the rapid cooling of large glass panes using air-jets to achieve thermal pre-stressing, using two wind boxes facing each other and fitted with front plates provided with numerous projecting blowpipes. Each box is divided into at least three separate chambers by walls located at 90 degrees to the front plate, and the press. of the air, which is above atmos. press. in each chamber, can be independently controlled. The wind boxes may consist of a middle chamber surrounded by four separate and independently-controlled chambers, and each chamber may be provided with one or more separate air inlets with flap valves. Used for toughening large panes of glass, e.g. where the front plate of the wind boxes must exceed 10m2.
