Abstract
Using a vessel which has a circular discharge port at the bottom and is provided with a nozzle in a coaxial arrangement with the port for ejecting a pressurized gas vertically downwards, a molten inorganic material such as a glass composition is allowed to vertically fall by gravitation as a hollow cylindrical stream. The fiberization of the molten material is accomplished by downwardly injecting a pressurized gas into the hollow of the cylindrical stream and, at the same time, blowing the pressurized gas at the cylindrical stream from a ring nozzle which is placed below the vessel and has downwardly and inwardly inclined orifices in a circumferential arrangement to surround the cylindrical stream.
