  • Method of and apparatus for bending glass sheets to relatively sharp angles
    Patent number: 4002450
    Abstract: A method of and apparatus for bending a flat sheet of glass to a relatively sharp angle. The apparatus includes a sectionalized, gravity mold structure provided with means for delivering electrical power to electrically conducting lines formed on the sheet supported on the mold apparatus and which lead to an electrically conductive path also formed on the sheet along a line about which it is desired to bend the sheet. Opposed electrical conductors, which also serve as locator stops, are biased into engagement with portions of the conducting lines to assure continuous current flow thereto during the bending and movement of the sheet into its desired configuration.
