Abstract

Method and apparatus for curving and tempering sheets of glass, while these move along a predetermined path through a heating zone, another area of bending and another cooling, which comprises heating the sheet of glass that is desired curving to the point of softening the glass while passing through said heating zone, advancing the hot sheet to the bending zone at a speed chosen in advance, interrupting the advance movement of the sheet at a particular location within said curving zone, and applying or exerting pressure on the opposite faces of the sheet to give it the desired curvature during such interruption of movement, the procedure being characterized by removing the curved blade from said curving zone and introducing it into the cooling zone cited above at a second speed relatively greater than the first, and then reduce this speed of movement of the When it enters the cooling zone to pass it through this zone at reduced speed while cooling the sheet.
