Abstract

PURPOSE: To bend plate glass at an acute angle and small curvature by vertically movably suspending a bender from the upper part of a heating furnace and providing the lender with a roadlike heater for heating the lending part of plate glass right above the bending part of the bending die frame in the furnace.
CONSTITUTION: Plate glass is heated all over in a heating furnace. When the glass temp. reaches about 550°C, the glass is further heated all over. The bending part alone is locally heated and bent. In order to strengthen the glass, it is further heated to about 640°C all over. At this time, part of the glass which part is not supported by frame 7 is supported by plate glass support rod 12, so droop of the glass due to its empty wt. can be minimized. Accordingly, esp. in case of long-sized plate glass, bent glass of high shape and dimensional accuracy can be obtd.
