ABSTRACT:
A mineral fiber-forming bushing is disclosed in which sidewalls containing at least one opening extend continuously downwardly from the bushing bottom wall to define a forming chamber beneath the bushing. A fluid is directed toward the bushing bottom wall and the exit of the fluid through the opening is controlled. The control of fluid flow can control the local environmental conditions both within the forming chamber and on the bushing bottom wall.
