Glass sheet bending apparatus
There has been known the so-called a horizontal furnace pressing system as a system for bend sheet. In such system, a glass sheet is heated at a temperature of about 200° C.-650° C. at a bend-processing stage in a heating furnace to bend it into a given curved form; the curved glass sheet is transferred to a cooling stage outside the heating furnace; cooling air is blasted to the curved glass sheet at the cooling stage to temper it, and then the tempered curved glass sheet is removed.
In the above-mentioned system wherein a glass sheet is bent at a high temperature in the heating furnace, it is possible to bend the glass sheet to have a complicated shape because the glass sheet is easily deformed under a high temperature condition in comparison with a system that a glass sheet is bent outside a heating furnace.
