APPARATUS AND METHODS FOR FABRICATING A GLASS RIBBON

Abstract:

Apparatus can comprise a conduit with at least one slot of a plurality of slots comprising an intermediate length including a maximum width that is less than a maximum width of a first end portion and/or a maximum width of a second end portion of the slot. In some embodiments, methods produce a glass ribbon with an apparatus comprising at least one slot within a peripheral wall of a conduit. In some embodiments, methods are provided for determining a volumetric flow profile dQ(x)/dx of molten material flowing through a slot in a peripheral wall of a conduit. In some embodiments, methods and apparatus provide a slot extending through an outer peripheral surface of a peripheral wall of a conduit that can comprise a width profile d(x) along a length of the slot to achieve a predetermined volumetric flow profile dQ(x)/dx of molten material through the slot.
