Abstract

The invention relates to bending of glass sheets moving in a horizontal position. In a first phase glass sheets are bent on a shaping bed made up of rotating elements, then in a second phase these sheets are subjected to a complementary bending between two molds of a bending press. Air flow is used to help support the glass in the second phase.
