A method and apparatus for bending and tempering glass panels includes a glass panel being heated to a tempering temperature and passed from a furnace's conveyor into a bending and tempering section for an arched roller mould, the glass bending upon its arrival thereon. The bent glass is subjected to a tempering blast. The first roller mould and a tempered glass article thereon are shifted out of the bending and tempering section in a direction substantially matching its own axis of curvature or the direction of rollers. The second, vacant roller mould is shifted into the bending and tempering section 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.
A method for bending and tempering glass panels, said method comprising heating a glass panel in a furnace to a tempering temperature and passing it into a bending and tempering section for an arched roller mould which has an axis of curvature substantially codirectional with the rollers and upon its arrival thereon the glass panel bends, after which the bent glass is subjected to a tempering blast, wherein the first roller mould, along with a bent tempered glass panel thereon, is shifted substantially codirectionally with its axis of curvature and the rollers out of the bending and tempering section and the second, vacant roller mould is shifted into the bending and tempering section for receiving the next glass article to be bent.
An apparatus for bending and tempering glass panels, said apparatus comprising a heating furnace for glass panels, a conveyor and a bending and tempering section within the furnace, which is provided with an arched roller mould forming an extension to the furnace's conveyor and having an axis of curvature codirectional with the rollers, as well as nozzle blocks above and below the roller mould for blasting tempering air to the opposite sides of a bent glass panel, wherein at least two arched roller moulds are adapted to be shifted in a direction substantially matching their axis of curvature, such that each roller mould takes its turn in the bending and tempering section as an extension to the furnace's conveyor while the other roller mould lies outside the bending and tempering section for the removal of a bent and tempered glass panel from the roller mould.
