Abstract
A process for bending a glass sheet according to which the glass sheet is heated in horizontal position until its bending temperature is reached and is brought into contact with an upper bending form by a force of a pneumatic nature. A fluid barrier is generated at the periphery of the glass sheet, the fluid barrier limiting the entry and exit of air near the upper bending form.
