The present invention relates to a process for laser scoring of flat glass sheets. The process comprises manipulating a laser beam having a substantially Gaussian intensity profile to produce an elongated heating zone on the glass sheet to be scored, the elongated heating zone having a central portion with a lower temperature than a temperature of an outer portion of the heating zone. An initial crack is made in the glass sheet, the elongated heating zone is traversed across the glass sheet coincident with the initial crack, and the heated glass is thermally shocked by directing a cooled liquid against the heated glass, thus propagating the crack. The scored glass sheet may thereafter be broken by applying bending techniques as are known in the art.

Apparatus (20,120) for forming a heated glass sheet G is disclosed as including a vacuum mold (22,22a,122,122a) having a full surface (24,24a,124,124a) against which a peripheral mold (26,26a,126,126a) presses the glass sheet periphery and with which at least one vacuum reservoir (32,33) is communicated within the interior of the sealed glass sheet periphery to form the glass sheet to the shape of the vacuum mold surface.

The invention relates to a production process for flat tempered glass, and belongs to the technical field of building materials. The production process comprises the following steps: cutting, edging and cleaning glass; placing the cleaned glass on a roller bed, and conveying the glass into a convection tempering furnace for heating treatment by virtue of the roller bed, wherein heating temperature in a first interval is 450 to 500 DEG C, heating time in the first interval is 100 to 250 seconds, heating temperature in a second interval is 680 to 700 DEG C, and heating time in the second interval is 200 to 300 seconds; discharging the heated glass out of the furnace, feeding the glass into a flat air grid, quenching the glass for 80 to 120 seconds under the air pressure of 0.1 to 4.8KPa by virtue of upper and lower air grids in the flat air grid until the temperature of the surface of the glass is 240 to 260 DEG C, and then quenching the glass to normal temperature to obtain a flat tempered glass finished product. The production process for the flat tempered glass is simple, easy, time-saving and energy-saving, the safety of the tempered glass is remarkably improved, and the bending strength and impact strength of the tempered glass are also remarkably strengthened.

A press bending station includes an annular mold (5) and a full-face mold (6). Holes (10), selectively connected to a negative pressure source, are placed in portions of the full-face mold (6) that are determined by the configuration of the annular mold when the annular mold comes into contact with a heated glass sheet (2) during the press bending process. The sheet (2) is drawn by negative pressure through the holes (10) towards the full-face mold (6) and thus acquires its shape. Positive pressure may be selectively applied to the holes (10) to release the sheet (2). According to the invention, at least some of the holes (10) are arranged in at least one groove (11) formed in the mold face of the full-face mold. The grooves (11) according to the invention accelerate considerably the removal by negative pressure of the air between the molding face of the full-face mold (6) and the glass sheet (2) to be bent and thus improve the press bending process.

Said method comprises the steps of heating the glass product material, shaping the heated glass product material into a glass product, cooling the shaped glass product, and inspecting the shaped glass products by means of at least one sensor sensitive to infrared radiation In said inspecting step a first image of the glass product is taken under a first viewing angle. In addition a second image of said glass product is taken under a second viewing angle which is different from the first viewing angle. The first image is compared with the second image for eliminating parasite reflections. The first and second images are analyzed for detecting whether said glass product is defective or not. An assembly is described for performing said method of producing glass products from glass product material.

Systems, methods, apparatus and products relate to drawing and blowing of ultra thin glass substrates, such as flexible display glass sheets, for example, organic light emitting diode (OLED) displays, liquid crystal displays (LCDs), and/or other flexible substrate applications, such as lighting, and/or other technologies, such as electro-wetting (EW), electro-phoretic display applications, etc. A localized heat source centripetally heats a vertical glass pre-form, while a pressurized air source blows the heated glass to expansion. An air bearing may centripetally blow air against the expanding pre-form to limit expansion and prevent contact of the pre-form with the localized heat source. Meanwhile, the pre-form is pulled vertically to draw the heated glass. The pre-form may float in a floatation mechanism to compensate for gravity when the pre-form is pulled upward. The blown and drawn pre-form may be cooled, coated with a polymer layer, and cut into a ribbon by in-line devices as it exits the air bearing. For example, a laser may helicoidally cut a polymer-coated blown and drawn pre-form into a ribbon, which may be rolled for collection.

When the electrical power source supplies electrical power to the sending coil, the sending coil wirelessly induces an electrical current in the receiving coil, which causes the dielectric panel to provide heat.

A method of molding a glass element in which a glass material is heated and then press-molded between an upper mold and a lower mold when a temperature of the heated glass material reaches a predetermined temperature. A first cooling of the glass element is performed with the glass element in contact with the pair of molds until a temperature of the glass element is within a range of +/-20 DEG C. of a glass transition point of the glass material while a pressure applied to the glass element by the upper and lower molds is gradually reduced until the pressure becomes 0 kg/cm2. Subsequently, a second cooling of the glass element is performed without the upper and lower molds contacting the patterned surface on the glass element. The upper mold has a bottom surface and a sidewall surface with a lowermost end portion of the side wall surface, adjacent the bottom surface, being inclined with respect to a central axis of the upper mold.
