ABSTRACT:
There is disclosed a method for bending a sheet of glass heated to a bending temperature in a horizontal furnace through which it is conveyed by a plane conveyor delivering the glass sheet to a bending cell heated to substantially the same temperature as the bending temperature. A concave annular recessed portion moves the glass sheet vertically towards a solid convex projecting portion within the cell, so that the sheet is squeezed between the concave and convex portions. A device for carrying out the method and its use for producing glazing with a particularly complex shape are also disclosed.
