The invention relates to a method and apparatus for bending and tempering glass panels. A glass panel heated to a tempering temperature is passed from a furnace's conveyor (4) into a bending and tempering section (5) for an arched roller mould (1, 2), the glass bending upon its arrival thereon. The bent glass is subjected to a tempering blast. The first roller mould (1, 2) and a tempered glass article thereon are shifted out of the bending and tempering section (5) in a direction substantially matching its own axis of curvature or the direction of rollers. The second, vacant roller mould (1, 2) is shifted into the bending and tempering section (5) for receiving the next glass article to be bent, the bending-tempering of which is performed at the same time as the bent and tempered glass article is being removed from the first roller mould. The gained benefits include an increased capacity, a shortened cycle time and an economically attractive, durable construction.
