ABSTRACT:
Process for bending and tempering glass sheets wherein the sheet (16) is heated up to its plastic state, and it bends by effect of gravity resting on a skelet-type mold (14), and next it is tempered by sudden cooling, in which process during the bending stage the glass sheet (16) is tilted with respect to the vertical direction by an angle of less than 90.degree.. Apparatus for carrying out said process, comprising a heating chamber (1) and a cooling chamber arranged in a sequence and assembled on a rotatable cylindrical frame whose axis is horizontal, said chambers being tiltable through rotation of the frame.
