  • Device for the manufacture of glass filaments
    Patent number: 4421538
    Abstract: A forehearth supplied with molten glass from a tank furnace, with bottom passages overlying bushings for the extrusion of vitreous filaments, forms an elongate chamber whose sidewalls are penetrated by heating electrodes spaced apart in the longitudinal direction and arrayed in two relatively staggered tiers. The electrodes of the lower tier are more numerous in the vicinity of the bottom passages than between these passages. The heating effect of the electrodes can be supplemented by top burners disposed above the glass level.
