  • 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.
    Type: Grant

    Date of Patent: January 6, 2015

  • Patent number: 7975509
    Abstract: A glass bending line for quickly shaping a complex bent glass sheet is provided that includes moving a ring-type female mold, which has a heated glass sheet placed on it, and a full face heated male mold, toward one another. Upon making shaping contact between the glass sheet and the male mold, a vacuum is applied through holes extending through the male mold, for a time sufficient to form the glass sheet to a desired shape. When the glass sheet has been shaped, the vacuum is terminated and pressurized air is connected to the holes to release the bent glass sheet from the male mold. The bent glass sheet is then quickly transported to a quenching station or an annealing station on a continuous conveying device. Hence, the complex bent glass sheet is achieved without the use of a shuttle ring.

  • Patent number: 4701425
    Abstract: A soda-lime-silica glass composition containing TiO.sub.2 for forming glass articles, e.g., glazings, the composition absorbing both infrared and ultraviolet radiation and having an Illuminant A (red and blue end of the spectrum) transmittance of about 68 percent or more, an Illuminant C transmittance of at least about 70 percent, and a solar ultraviolet transmittance of about 50 percent.
