<p>A bushing balance controller senses the temperature of each section (14, 16, 18) of a multiple section glass fiber forming bushing (12) by resistance (voltage drop) measuring techniques and injects electrical energy to all but one of the individual bushing sections and adjusts the supply of electrical energy to the entire bushing assembly thereby controlling the temperature of each individual section of the bushing. A controller (102) uses wires (104, 106, 108, 110) connected to the bushing (12) to sense the voltage drop across each bushing segment (14, 16, 18). The controller applies power to the entire bushing through power pack (26) or only to individual segments through separate power packs (50, 70).</p> |
