Abstract
A process and device for obtaining bent-tempered motor vehicle glazings exhibiting a greatly bent marginal zone comprises a glass sheet heated in a furnace and shaped by pressing the glass sheet between a solid upper form and a bending frame, of which at least one side part is bent during pressing. The side part is covered with an elastically deformable felt material and is removed from the glass sheet during tempering, while the main part of the glass sheet remains supported by the bending frame which also serves as a tempering frame.
