Abstract
A feeder system for the production of glass filaments is provided with a shallow layer of molten glass over the discharge wall in combination with a flow control means adapted to regulate the depth of the layer to provide dripless and non-dripless operation as desired. Preferably, the feeder is rendered non-dripless when the restart of filament formation from the idled orifices is desired.
