  • Method and apparatus for the environmental control of fiber forming environment
    Patent number: 4853017
    Abstract: The present invention relates to an improved method and apparatus for controlling the air quality in the fiber forming zone of glass fiber manufacturing operation. The present invention provides a housing extending from the bushing to the applicator roller, the housing intended to prevent the recirculation of air containing contaminated particulate into the fiber forming zone. Clean air is supplied with the housing at desired flow rates to maintain temperature and air flow requirements.
