PROCESS AND APPARATUS FOR FORMING MINERAL FIBERS ABSTRACT OF THE DISCLOSURE The invention relates to a process and apparatus for the manufacture of fibers from attenuable materials, such as glass making materials, by centrifugation. In a process in which the attenuable material is directed onto the peripheral surface of a centrifugation wheel which is enveloped by a gas current produced by a blowing crown, the invention comprises the projecting onto the fibers of a liquid composition from a centrifugation element, the projection being carried out close to the wheel in the form of drops which penetrate and are atomized by the gas current. The apparatus of the invention includes a projection element rotating with the centrifugation wheel for centrifugal de- livery of the drops of liquid composition. The invention provides a very uniform treatment of the fibers, particularly by means of liquid binder compositions.
