Abstract

PURPOSE: To improve the quality of a heated and softened linear fluorescent lamp by heating its predetermined inside wall surface and making its thickness uniform when it is bent circularly.
CONSTITUTION: The linear lamp 4 is put in a heating furnace, heated, and cured. Then, it is positioned between the pulleys 6' and 6' of the formation drum 6. Simultaneously with the joint of the pulley 6', the lower section of the lamp 4 is supported by holding pieces 9 and 9. The heating burner 10 starts its heating together with the actuation of the holding pieces 9 and 9 and heats the predetermined inside wall surface at the circular molding of the lamp 4 during its molding process. This permits the inside and outside temperatures to be uniformalized and cracking and one-side thickness to be prevented.
