发明名称 BENDING FORMING PROCESS OF BAR GLASS
摘要 PURPOSE:To prevent a bent part of a strip-shaped glass plate from becoming of heavy thickness and to obtain high reliability of product suited for spacer frame of a fluorescent character display tube, etc. by bending a strip-shaped glass with its heated side placed inside. CONSTITUTION:After softening a part of a strip-shaped glass plate 1 to be bent by heating with a gas torch 2, the gas torch 2 is moved away toward a position not inhibiting the bending work. Then, immediately, an end of the glass piece is pushed toward the position where the gas torch 2 has been placed. By this procedure, the thickness of the bent part is not reduced but is rather increased, and the softened part is bulged out toward the inside of the thickness direction, and is also projected toward the height direction of the spacer. By pressing the projected part toward the height direction to make it flat by quickly pressing jigs 3 almost simultaneously from above and below before the bent part is hardened by cooling, and a desirable frame for a spacer glass is obtd.
