Reshaping Of Planar Sheet Patents (Class 65/106)
  • Patent number: 10640411
    Abstract: A device for bending sheets of glass, includes conveying rollers that convey the sheets one after another in a longitudinal direction, carrying them under an upper bending die and onto a receiving surface formed by the upper level of the rollers under the die. The device includes an intermediate support including a contact path for supporting the sheet of glass to be pressed lying under the die. The contact path has, parallel to the edge of the sheet to be pressed, a curvature that is less accentuated than the curvature that is to be imparted by the upper die. The intermediate support can rise above the receiving surface and support the sheet to be pressed until the sheet breaks contact with the rollers. The intermediate support can be lowered down below the receiving surface. A sheet-pressing system can press the periphery of the sheet against the upper bending die.

  • Patent number: 9922790
    Abstract: At the time of temporary firing for fixing a glass layer 3 to a glass member 4, the glass layer 3 is irradiated with laser light L2 having a ring-shaped irradiation region. At this time, in a width direction of the glass layer 3, two peaks M in a beam profile of the laser light L2 respectively overlap both edge parts 3b of the glass layer 3. This allows a center part 3a and each of both edge parts 3b of the glass layer 3 to be irradiated for shorter and longer times with a part having a relatively high intensity in the laser light L2, respectively. As a consequence, the amount of heat input by irradiation with the laser light L2 is homogenized between the center part 3a and both edge parts 3b in the glass layer 3, whereby the whole glass layer 3 is molten appropriately.

The glass-bump spacers are formed in the surface (24) of one of the glass panes (20) and consist of the glass material from the body portion (23) of the glass pane.

Methods of forming VIG windows are also disclosed. The methods include forming the glass-bump spacers by irradiating a glass pane with a focused beam (112F) from a laser (110). Heating effects in the glass cause the glass to locally expand, thereby forming a glass-bump spacer.

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.

  • Patent number: 8925352
    Abstract: The present invention relates to a method of shaping a glass sheet in one dimension, by roll forming in a manner to selectively minimize/eliminate undesired curvature from the glass sheet. Such shaping is achieved by the selective location in first and second, shaping zones, of shaping rolls having first and second shaping configurations and, optionally, by varying the velocity of the glass sheet as it moves through the shaping zones, thus varying the time portions of the glass sheet are in contact with certain shaping rolls.

    Abstract: A method for the production of glass components, an apparatus for carrying out the method and a glass component that is obtainable through the method are provided. The method is a drawing method wherein a forming zone of a preform is heated to a temperature that allows drawing of the glass. The method is characterized in that the forming zone of the preform is very small. Thereby the width of the preform is decreased to a smaller extent than its thickness. The glass components that can be obtained by this method have very smooth surfaces.

    Abstract: A process using a three-piece mold for making a three-dimensionally shaped glass article having a flat area and a curved/bend area is disclosed. The process includes placing a glass sheet on a mold having a shaping surface with a desired surface profile for the shaped glass article including a flat area and a bend area, moving a flat area plunger toward the glass sheet to compress the glass sheet, heating a portion of the glass sheet corresponding to an area above the bend area of the mold to a temperature above a forming temperature, and moving a bend area plunger toward the heated glass sheet to compress the heated glass sheet. A temperature of the glass sheet in the area above the bend area of the mold is higher than a temperature of the glass sheet in the area above the flat area of the mold when compressing the heated glass sheet with the bend area plunger.

  • Patent number: 8850850
    Abstract: To produce a meniscus lens from synthetic quartz glass for use in a microlithography apparatus, which lens has a first optical surface (7) and a second optical surface (8) with the same direction of curvature as the first optical surface (7), SiO2 particles are formed by oxidation or flame hydrolysis of a silicon-containing starting compound and deposited layer by layer on a substrate to form a cylindrical SiO2 blank which contains layers with a surface normal extending in the direction of growth. To allow such layers, which have however the least possible adverse effect on optical or mechanical properties, it is proposed according to the invention that the blank is plastically worked in a hot forming process under the effect of a deforming force to form a preform (6), which has at least the first curved surface (7) and in which the layers are curved in the direction of curvature, and that the meniscus lens is obtained from the preform.
