FINSHIELD ASSEMBLIES FOR FIBER-FORMING APPARATUS

摘要

An apparatus for producing glass fibers comprising a bushing (32) with a tip plate (34) including a plurality of openings therein from which streams of molten glass are discharged and a heat-absorbing finshield assembly (30), which is located adjacent the discharge area of a furnace (40) for producing glass fibers, includes fins (2) spaced along a fluid-cooled manifold (33) such that the fins (2) extend between, but not in contact with, the molten glass fibers (44) emerging from the furnace (40). The fins (2) may have microfins (8) in their bases which are in contact with the cooling fluid. The fins (2) are of diverse thicknesses along the manifold (33) to absorb different quantities of heat from the emerging fibers (44).
