A method and apparatus for centrifuging fibers from molten material comprises a spinner having a peripheral wall comprised of an inner layer and an outer layer, a plurality of orifices extending through the inner layer for the passage of molten material therethrough, and a plurality of cavities extending through the outer layer, the cavities generally corresponding to the orifices, the cavities having being sufficiently large so that a) fiber forming cones form where the orifices join the cavities and b) the fibers formed from the cones can exit the cavities without contacting the sides of the cavities.
