Abstract

The production of fine fibers from a hardenable thermoplastic material in a viscous state particularly glass fibers from molten vitreous material, by dropping one or more streamlets or threads of the material onto a horizontally disposed disc-shaped body rotating rapidly around a vertical axis, at an inner radial portion thereof, whereat is provided an annular trough for the supply of material which flows outwardly from the top of the trough onto the upper surface of the body and is projected thereover in sheet form by centrifugal force over the peripheral portion of the body which is perforated with a plurality of substantially vertical orifices. An annular burner below the disc-shaped body serves as a source of hot gas under pressure which is blown upwardly through the orifices to product the material into filaments, which are thereafter drawn out into fine fibers by an annular gaseous blast directed radically and substantially horizontally above the peripheral portion of the body to turn down the substantially vertical filaments while attenuating them, which is followed by the withdrawal thereof.
