  • Patent number: 11518705
    Abstract: A nozzle tip for producing glass fibers has a pair of long-side walls and a pair of short-side walls, each of the long-side walls and the short-side walls containing platinum or a platinum alloy, and a nozzle orifice for discharging the glass melt, the nozzle orifice being formed by the long-side walls and the short-side walls. The nozzle orifice has a flat hole shape in horizontal cross-section. Each of the long-side walls has a cut-out on a discharge side of the glass melt, a width of the cut-out being 10-55% of a length of a longitudinal center axis of the flat hole shape of the nozzle orifice. The pair of long-side walls has a symmetrical shape about the center axis of the nozzle orifice. This nozzle tip makes it possible to efficiently produce glass fibers having a desired cross-sectional shape.
