  • Patent number: 11305516
    Abstract: Laminated glazing, once limited to just the windshield, is finding more and more application in other positions on the vehicle due to its ability to improve passenger safety, security and comfort. Problems are encountered when producing a laminated version of a tempered part with holes, because tempered glass is 4 to 5 times stronger than annealed glass. The laminate of the invention has a hole in the exterior glass layer. An insert is bonded to a cutout in the area of the hole on the interior glass layer so as to reinforce the hole and distribute the load over a wider area. The result is a laminated glazing with one or more holes that has the reliability of and is a direct replacement for a tempered part.

    Abstract: A non-contact shaping device includes a first fixture including a fixing section structured to alternately blow out and suck in gas. The fixing section may fix, through suction of gas, a glass plate thereon. An optic heat source processing device is selectively set above predetermined portions of the glass plate to heat, in a non-contact manner, and thus soften, in a temperature-controlled manner, the portions for curving and suspending downward along an edge of the fixing section. The curved glass plate is then lifted up through blowing gas from the first fixture. The second fixture selectively covers the curved glass plate and blow gas therefrom to flow, in collaborative combination with the gas blown from the first fixture, around surfaces of the curved glass plate for cooling and fixing a shape of the curved glass plate in a non-contact manner to form a three-dimensional curve-surfaced glass product.

  • Patent number: 10370282
    Abstract: A method and an apparatus for tempering glass sheets. A glass sheet is heated to a tempering temperature and quenching is conducted by blasting cooling air to both surfaces of the glass sheet. The quenching of a top surface and a bottom surface of the glass sheet's both side portions is commenced earlier or is performed at the early stage of quenching more effectively than the quenching of a top surface and a bottom surface of the glass sheet's intermediate portion. As a result, the compression stress required for a desired tempering degree is established on both surfaces of the side portions earlier than on both surfaces of the intermediate portion. In order to achieve this, the cooling air enclosures above and below a glass sheet are provided with a subarea of weakened cooling effect.

The apparatus also includes an upper press at least partially disposed within the upper press ring and configured to shape at least a section of the glass sheet inside the perimeter section of the glass sheet, including forming by use of applied vacuum. The inner press may include openings that apply vacuum in selected areas of the inner press to vacuum form the ply within the selected areas. To control the ply on the upper press assembly, vacuum that is applied though passageways in the upper press ring to the gap between the upper press ring and the inner press is controlled through a seal in the gap. The upper press ring includes pivotal joints that increase adjustability of the forming surface of the upper press ring to the face surface of the inner press.

  • Publication number: 20140352357
    Abstract: A furnace for shaping glass sheets for aircraft transparencies using the cut-to-size method includes a preheat and cooling furnace defined as a first furnace, and a shaping furnace. A conveyor geared for reciprocating movement moves a bending iron supporting a glass sheet through the first furnace set to a preheat temperature. The glass sheet supported on the bending iron is heated in the shaping furnace by microwave beams from a gyrotron to heat portions of the glass sheet to be shaped to a complex shape. After the sheet is shaped, the conveyor moves the bending iron supporting the shaped glass sheet from the shaping furnace through the first furnace set to a cooling cycle.

  • Patent number: 8839644
    Abstract: A method of manufacturing of strengthened glass containers, and more particularly a method of thermally strengthening glass containers in a glass container manufacturing line at a location intermediate the hot end and the cold end. Glass containers formed at an I. S. machine are conveyed through a special tempering Lehr that heats them uniformly to a high temperature that is short of temperatures at which they may become deformed. Subsequently, the glass containers are subjected to a unique rapid thermal strengthening cooling process in which the outer and inner surfaces including all areas of the glass containers are simultaneously cooled to a temperature below the Strain Point of the glass used in the glass containers.

  • Publication number: 20130258569
    Abstract: Disclosed are methods for making an enclosure having a three-dimensionally shaped glass wall portion comprising an initial step of shaping a glass charge into a preform having a preform cross-section corresponding in shape to a smaller cross-sectional shape for the three-dimensional glass wall portion. At least a surface portion of the preform is then finished if necessary to remove any visible optical surface defects therefrom and/or to meet geometric tolerances, and the preform is drawn along an elongation axis perpendicular to the preform cross-section to reduce or draw down the preform in size to the smaller cross-sectional shape for the three dimensional glass wall portion. The smaller cross-sectional shape or sections thereof are then tempered to provide a strengthened glass wall portion having a compressively stressed surface layer thereon.
