Abstract A method of and a furnace assembly for bending glass sheets. Glass sheets (6) are conveyed in bending moulds (5) supported by cars (4) along an upper transport run (2) periodically from one heating sect- ion (10) to another. In the final heating section, temperature isrisen so high that a glass sheet bends by the action of heat and gravity to conform with the surface of the mould. Thereafter, a car (4) together with a bent glass sheet is lowered onto a lower run (3) and returned to the outset of a furnace (1). On cooling, the glass sheets on said lower run emit heat to the glass sheets on said upper run through the open bottom structures of cars (4). The weight and heat capacity of the cars have been made as low as possible by removing the side and back walls thereof, whereby only the front or leading walls (8) provide locking walls between sections (10) successive in the longitudinal direct- ion of the furnace.
