ABSTRACT:
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.
