Abstract
A feeder system for the production of glass filaments is rendered dripless or non-dripless on demand by controlling the pressure of the air in contact with the streams and beads of the orificed discharge wall. Preferably, the feeder is rendered non-dripless when the restart of filament formation from idled orifices is desired.
