    Abstract: Apparatus for producing glass filaments wherein streams of molten glass material flow through an array of orificed tips projecting from a heated bushing. The streams of molten glass material are then attenuated into filaments. A uniform filament forming environment is attained by employing a fence adjacent boundary tips in the array of tips to heat such boundary tips by radiation, reflection or conduction. The fence is heated independently of the bushing so that a controlled quantity of heat is supplied to the boundary tips to compensate for losses which may vary with varying ambient conditions. The fence may be shaped to direct heat toward the boundary tips.
