Abstract
A process for bending glass plates into convex shape and, in particular, to their precise positioning with a view to that bending. The glass plates to be convexed are centered while a hot gas is blown under said plates in order to take up a part of the weight of the glass thanks to that blown gas. It makes possible a recentering of the glass plates without deterioration of said plates in spite of their friction on the rollers carrying them.
