According to one or more embodiments disclosed herein, a glass sheet may be formed by a method which includes supplying a feed of molten glass to an upper surface of a pair of forming rolls, and rotating the pair of forming wheels to continuously form a glass sheet from the molten glass. The pair of forming rolls may be spaced apart by a forming gap, and the forming gap may have a width of less than or equal to about 800 microns. The molten glass may have a viscosity of less than or equal to about 200 poise. The glass sheet may have a thickness of less than or equal to about 800 microns immediately upon passing though the forming gap.

A tool for local cooling by contact of a glass sheet at a temperature higher than 450 C., known as a contact tool, includes a contact face suitable for coming into contact with the glass sheet, the tool including an internal pipe for the circulation of a coolant, in particular air. The tool is used in a device for bending and/or cooling a glass sheet, in particular individual, the tool coming into contact with the glass sheet while it is held by a bending tool or by a cooling frame after bending. A compression zone is created that is capable of being drilled to form an edge having compressive stresses.
