Heating furnace for a device for drawing a plastic optical fiber |
摘要 |
A heating furnace is used in a drawing device for drawing a base material made of plastic. The base material is fed into the heating furnace, melted under heat and drawn into a plastic optical fiber. The heating furnace is divided into a pre-heating zone located upstream and a heat-melting zone located downstream in the advancing direction of the base material and of the plastic optical fiber made therefrom. The preheating zone includes a pre-heater for pre-heating the base material, while the heat-melting zone includes a melting heater for melting the base material. Both zones are controllable independently so as to give an appropriate temperature for each zone.
