Abstract
A method of manufacturing a gas-filled triple glazing, including: a pre-assembly during which three sheets of glass are positioned beside one another, at least one of the sheets of glass including a spacer, each sheet of glass being positioned inclined by an angle between 0° and 10° with respect to an adjacent sheet of glass, to form two cavities, each of the cavities being between two adjacent sheets of glass; filling the two cavities by injecting gas into the two cavities at a same time using nozzles; pressing the sheets of glass against one another to seal the triple glazing. The method allows triple glazing to be manufactured quickly.
Claims19
A method of manufacturing a gas-filled triple glazing, the method comprising:
- a pre-assembly during which three sheets of glass are positioned beside one another, including positioning a first sheet of the sheets of glass on a first belt strip, positioning a second sheet of the sheets of glass on a second belt strip, and positioning a third sheet of the sheets of glass on a third belt strip, with a single spacer to separate the sheets of glass, each sheet of glass being positioned inclined by an angle of 0° to 10° with respect to an adjacent sheet of glass, so as to form two cavities, each of the cavities being between two adjacent sheets of glass;
- filling the two cavities by injecting a gas into the two cavities at a same time using nozzles via orifices made in a conveying belt conveying the sheets of glass;
- pressing the sheets of glass against one another to seal the triple glazing,
- wherein the single spacer is fixed to the sheet of glass situated between the other two, the single spacer being fixed on at least one of the faces of the sheet of glass situated between the other two so that, following the pre-assembly, the single spacer delimits two cavities, and
- wherein the method includes, prior to the pressing, moving the first belt strip, the second belt strip, and the third belt strip closer together to perform a cursory pressing of the first sheet, the second sheet, and the third sheet.
