Abstract
A feeder for the production of glass filaments is provided with a shallow layer of glass over the discharge wall in combination with a fluid filled cavity capable of being pressure regulated to render the operation dripless or non-dripless as desired. Preferably, the feeder is rendered non-dripless when the restart of filament formation from idled orifices is desired.
