DEFINITION

Classification: 65/454

Formation of fiber or preform utilizing fluid blast (e.g., from molten glass, etc.):

(under subclass 376) Processes wherein a forcible stream of an extraneous fluid is directed against (a) a molten glass stream, or (b) a rod or filament in a plastic state to subdivide the stream rod or filament into discrete fibers or fiber preforms.
