Abstract
PURPOSE:To make it possible to manufacture a bent type fluorescent lamp with flat section easily and at a high yield rate without increasing the number of processes and assembling lines in particular, by processing the discharge passage in a flat section just prior to the bending process of the straight tube type glass tube. CONSTITUTION:When a straight tube type glass bulb 10 is heated by a heating furnace 15 up to the softening temperature, the straight tube type fluorescent lamp is delivered between formation patterns 30 and 30. By contacting the formation surfaces 31 and 31, the straight tube type glass bulb 10 is pressed except the electrode installing ends, and the bulb 10 is formed into a flat shape. Therefore, only a flatting process may be added between the heating and softening process and the bending process of the conventional process to produce the bent type fluorescent lamp of a circular section, and the number of processes and the assembling lines is not increased particularly. And, since the heating of the bulb is carried out in the condition of the straight tube form, uneven heating and the like are never generated, and the processing efficiency and the yield rate can be improved.
