    摘要: In an apparatus for producing glass fibers wherein an orifice plate formed with a greater number of orifice holes in high density is provided to draw glass fibers therethrough and air nozzle means is provided for impinging air flow against the undersurface of the orifice plate so that the adjacent cones of molten glass formed on the undersurface of the orifice plate may be prevented from coalescing to each other, an air nozzle assembly is provided which includes a plurality of tubular nozzles arranged in such a way that their discharge ports may be arranged in line and in parallel with the longitudinal direction of the array of orifice holes in the orifice plate and spaced apart from each other by a predetermined distance. High cooling efficiency may be attained with a less consumption of cooling air; the undersurface of the orifice plate may be uniformly cooled; the operation for separating a bead of molten glass formed on the undersurface of the orifice plate into individual cones may be facilitated; and the filament or fiber breakage due to the impingement of the air jets may be avoided.

    摘要: Disclosed is an orifice plate for use in a bushing for spinning glass fibers having a number of orifices each of which consists of two cascaded coaxial cylindrical bores of different diameters, one of which opens in the upper surface of the orifice plate to constitute a molten-glass inlet-side bore, while the other opens in the lower surface of the orifice plate to constitute a molten-glass outlet-side bore.The orifices are so densely arranged as would allow joining of molten glass cones formed at adjacent orifices if a suitable countermeasure such as a cooling by air flow were not taken. In order to compensate the reduction of flow rate of the molten glass through the outermost orifices attributable to a larger ratio of heat radiation to heat absorption at the outermost orifices than at the inner orifices, a specific dimensional relationship is provided between the outermost and the inner orifices such that glass cones of the same size and shape with those of glass cones of inner orifices are formed at the outermost orifices irrespective of the difference of the heat radiation between the outermost and the inner orifices, thereby to decrease the frequency of occurrence of breakage of filaments at the outermost glass cones which has often taken place to interrupt the continuous spinning.

    摘要: In a process for spinning glass fibers continuously from a nozzle plate having 25- 200 orifices per cm.sup.2, a start-up operation is improved by using the nozzle plate made of a material having a contact angle of 60.degree. or more, drawing flooded molten glass which has spread over the whole undersurface of the nozzle plate at a greater speed than the flowing speed of the molten glass by its own weight from each orifice, while maintaining the normal spinning temperature, and finding the ends of the individual filaments.

    摘要: The orifice plate 2 in the bottom of a bushing 1 is uniformly inwardly curved in a concave manner, whereby its resistance to outward deformation or sagging under the weight of molten glass in the bushing and the tension of glass filaments 5 withdrawn therethrough is greatly increased. The plate may be rectangular or circular, i.e. arch-shaped or domed, and may be further strengthened by reinforcing bars 7 secured to the interior side walls of the bushing and to the crown portion of the plate.

    摘要: A method of detecting breakages of glass fiber filaments being drawn through orifies of an orifice plate by converting the variation in intensity of radiant light or heat emitted from a bead of molten glass which grows on the undersurface of the orifices plate at an orifice at which a breakage occurs into an electrical signal by a radiation thermometer which is so arranged as to reciprocate horizontally in parallel with both one side and said undersurface of said orifice plate, whereby the breakage may be detected.

    摘要: Disclosed is an orifice plate for use in glass-fiber spinning having a number of densely arranged orifices. Each orifice has a larger diameter at the inlet side thereof facing the molten glass and a smaller diameter at the outlet side thereof facing the ambient air. The ratio of the larger diameter to the smaller diameter is so selected to fall within a range between 1 : 0.4 and 1 : 0.9. The reduced diameter of the orifices at their outlet side provides sufficiently large space between adjacent orifices at their outlet sides, in spite of the high density at which the orifices are arranged, so that the joining of glass cones suspended from respective orifices is conveniently avoided even after the brims of the orifices are ground by the viscous cooled molten glass.
