Abstract
A method for fiberizing mineral material with organic material includes centrifuging mineral fibers from molten mineral material with a first spinner rotating about an axis, changing the direction of the mineral fibers to form a downwardly moving veil of mineral fibers, establishing a flow of molten organic material moving downwardly in a first conduit positioned within the veil, and directing the flow of molten organic material to a position beneath the spinner, dividing the flow of molten organic material into a plurality of streams, directing, by means of individual conduits, individual ones of the plurality of streams radially outwardly away from the first conduit, rotating the individual conduits about the axis, centrifuging organic fibers from the molten organic material by means of nozzles at the radially outward ends of the individual conduits, and directing the organic fibers into contact with the veil of mineral fibers.
