    摘要: The principles and embodiments of the present disclosure relate generally to complexly curved laminates made from a complexly curved substrate and a flat substrate, such as automotive window glazings, and methods of cold forming complexly-curved glass products from a curved substrate and a flat substrate. In one or more embodiments, the laminate includes first complexly-curved glass substrate with a first surface and a second surface opposite the first surface, a second complexly-curved glass substrate with a third surface and a fourth surface opposite the third surface with a thickness therebetween; and a polymer interlayer affixed to the second convex surface and third surface, wherein the third surface and fourth surface have compressive stress values respectively that differ such that the fourth surface has as compressive stress value that is greater than the compressive stress value of the third surface.

    摘要: Disclosed are embodiments of a method of forming a curved glass article. In the method, a mold having a curved surface is provided. A self-adhesive layer is disposed on the curved surface. A glass sheet is bent into conformity with the curved surface at a temperature less than the glass transition temperature of the glass sheet. The glass sheet includes a first major surface and a second major surface in which the second major surface is opposite to the first major surface. The first major surface is adhered to the self-adhesive layer. A frame is bonded to the second major surface of the glass sheet, and the glass sheet is removed from the self-adhesive layer. A system for performing the method and a mold having a self-adhesive layer are also disclosed.

    摘要: A sheet of glass can be formed in a batch process by introducing molten glass onto a layer of molten tin within a tank. The tank may be outfitted with infrared emitters to control the amount of heat delivered to the tank while the sheet of glass is formed. A lower surface of the tank can have a three-dimensional shape, and the molten tin may be removed from the tank while the sheet of glass is ductile so that the sheet of glass is molded by the three-dimensional shape, thereby producing a shaped sheet of glass. The delivery of infrared energy to the tank may be facilitated by one or more ceramic glass surface.

    摘要: A method of forming a glass article includes providing a first glass sheet. The first glass sheet is heated to a temperature suitable for shaping. The first glass sheet is deposited on a first bending tool. An edge portion of the first glass sheet is disposed over a shaping surface of the first bending tool. The shaping surface of the first bending tool is configured to provide in the first glass sheet a compression area and a tension area. The first glass sheet is shaped on the first bending tool and the compression area is formed in the edge portion of the first glass sheet. The compression area includes a first portion and a second portion. The first portion has a width which is greater than a width of a second portion.

    摘要: A glass bending device is presented. The glass bending device includes a bending chamber, a tool for holding at least one glass pane by means of a suction effect, including a downward-directed frame-like, convex contact surface and a cover with a peripheral air-guiding plate surrounding the contact surface at least in regions. The tool is suitable for sweeping the edge of the glass pane at least in sections with an air flow and thereby pressing the glass pane against the contact surface. The glass bending device further includes a fan, which is connected to the bending chamber via a feed line and a return line and is suitable for extracting air from the bending chamber via the tool and the feed line to produce the air flow and for returning air back into the bending chamber via the return line. The return line is connected to the bending chamber above the tool.
