Abstract
A method is disclosed for controlling the environment below a glass fiber forming bushing. A fog or mist is created below the bushing by forming an air vortex in front of the bushing which carries water or another liquid cooling fluid upwardly towards the bushing. The cooling liquid is misted or fogged below the bushing. This mist or fog absorbs heat from the bushing and the apparatus in the region below the bushing and helps cool the environment below the bushing. In addition, this mist of cooling fluid acts as a radiation shield to reduce the amount of heat radiated from the bushing and other apparatus toward the operator of the forming position and thus aids in his comfort.
