Zusammenfassung:	Curving of glass sheets by application of said sheets against an upper curving form and possibly subsequently, after the deposit of said sheets onto a lower curving form, by depressing in accordance with said upper form is improved. After the taking up of a sheet of glass by the upper form, a current of hot gas is blown under the glass sheets in order to produce a pneumatic pressing. The process and opportunities enables the manufacture of curved glasses in accordance with complicated shapes and/or with an accentuated curvature but, nevertheless, with a surface free from defects.
