Abstract

In a method for bending glass plates, the glass plates are heated in a horizontal position in a continuous furnace (1) to the bending temperature and in a following bending chamber (5) are pressed by an upwardly flowing hot gas stream against a convex bending mold (7) positioned above the conveying plane. The bent glass plates (3') are placed on a displaceable shaping ring (13) and transferred with the latter into a following cooling station (16). The glass plates (3) are raised from the conveying roller train (2) of the continuous furnace (1) by a suction plate (3) are positioned relative to the transfer ring (28) on the latter. With the aid of the transfer ring (28) the glass plates (3) are transferred into the bending chamber, where in the end position of the transfer ring (28) they assume the desired end position relative to the bending mold (7).
