Abstract

PURPOSE: To promote the efficiency of the local heating operation remarkably and prevent the staining of a plate glass, by heating the plate glass uniformly in a heating furnace, and heating the desired bending part at a high temperature by the operation on the outside of the furnace.
CONSTITUTION: A ribbon heater 21 is fixed at supporting frames (9a) and (9b) of a frame 7 by metallic fixtures 19 to coincide with the desired bending position of a plate glass (G) an moved in a heating furnace 1. A linking member 12 is linked to a rod of a cylinder 13 to fill a groove 14 with a refractory material. The supporting frame 9 is retreated by the cylinder 13, and the heating furnace 1 is operated to carry the plate glass (G) hung from a trolley 4 in the heating furnace 1 and uniformly heat the plate glass (G). The plate glass (G) is then stopped at the position of the frame 7, and the supporting frame 9 is advanced by the cylinder 13 to bring the heater 21 near the given bending part of the plate glass (G). Only the given bending part is heated to a high temperature. After completing the heating, the plate glass (G) is taken out of the heating furnace 1 and moved to the next bending step.
