Insulated tongs for supporting glass sheets during press bending to v shapes and process of use

Abstract From the Canadian patent

TONGS FOR SUPPORTING GLASS, SHEETS DURING PRESS BENDING TO "V" SHAPES Abstract of the Disclosure, When glass sheets are bent to "V" shape by press bending and electrical current is used to provide localized heating along the intended line of a sharp bend, it is necessary to insulate the glass electrically from ground. This is done according to the present invention by providing the pressing molds that engage the glass with covers of electrical insulator material, such as fiber glass and by incorporating in the glass, suspending means or tongs a length of electrical insulator material sufficiently long to effectively insulate the metal tongs that engage the glass from the tong suspension …
