Method and apparatus for bending and tempering glass sheets

A method of bending and tempering glass sheets as they are moved along a predetermined path through successive heating, bending and chilling areas, the sheets being supported on heated gases during movement through said heating area where they are brought to their softening temperature and on relatively cool gases during movement through said chilling area to temper the sheets, is characterized in that the forward movement of the sheets is interrupted in said bending area and while maintained stationary the sheets are pressed into the desired curvature between complemental shaping surfaces before they are passed into the chilling area. Glass sheets S (Fig. 2, not shown) are fed into a heating area B on a conveyer 20. The heating area comprises a set of seven heating boxes 46 in side-by-side relationship. Hot gases are burnt within opposed chambers 52 (Fig. 7, not shown) of the boxes, the gases issuing through orifices 58 in the opposed faces 48 of the boxes. The faces ...

METHODS OF TOUGHENING A GLASS SHEET

ABSTRACT OF THE DISCLOSURE This invention relates to the toughening of glass sheets. A glass sheet is toughened by quenching the sheet after it has been contacted by shaping surfaces. Prior to quenching, for example in a chilling liquid, the glass sheet is heated throughout its bulk to a pre-quenching temperature which is higher than the temperature of the glass while it was being shaped. The glass sheets are for use in the manufacture of windscreens for motor vehicles and aircraft.
