ABSTRACT:
In apparatus for bending a flat sheet of glass to a relatively sharp angle wherein the apparatus includes a sectionalized, gravity mold structure provided with means for supplying electrical power to electrical conductor lines formed on the glass sheet supported on the mold apparatus and which lead to an electrically conductive path also formed on the sheet along the line about which it is desired to bend the sheet. Opposed electrical contactors, forming a part of the electrical supply means, are urged into engagement with portions of the conductor lines leading to the path to provide continuous contact therewith and uninterrupted current flow during the bending operation. After bending, these contactors are displaced from such conductor lines into an out-of-the-way position for easy removal of the bent sheet and the replacement thereof with a fresh sheet.
