Abstract
Glass fibers having an etchable or leachable core are used to fabricate glass nozzle arrays. A plurality of fibers are aligned in spaced parallel relationship with one another, and their major longitudinal portions are encapsulated with either a resin material or solder glass to form a block of material. This block is sliced orthogonally to the longitudinal axes of the fibers to form thin sections of nozzle arrays. After lapping and polishing, the inner cores of the glass fibers are etched out to form orifices. The use of solid core glass fibers prevents the nozzles from filling or becoming clogged with debris and dust from preceding forming operations.
