Patent ID: 8210002

Claim:
A system for controlling the temperature of a glass fiber forming bushing having multiple segments, comprising: (a) a glass fiber forming bushing comprising: a tip plate comprising orifices adapted to pass glass to form filaments; a first side wall opposing a second side wall extending upwardly from the periphery of the tip plate; and a first end wall opposing a second end wall extending upwardly from the periphery of the tip plate and connected to the two side walls to form a reservoir for molten glass; (b) a source of current coupled to a terminal on the first end wall and coupled to a terminal on the second end wall; (c) at least one terminal on the first side wall and at least one terminal on the second side wall; (d) means for regulating the current passing through each bushing segment, the means for regulating being coupled to the terminal on the first side wall; (e) means for measuring the size of fiber glass formed from the bushing; and (f) a controller in communication with the measuring means and the regulating means.
