Molten glass separating device in glass fiber forming apparatus

Abstract From the Canadian patent

In a glass fiber forming apparatus wherein is used an orifice plate which has a large number of closely spaced orifices and has a flat undersurface and air is blown upwardly against said orifice plate during spinning operation, means is provided for mechanically separating into individual glass fibers a mass of molt-n glass adhering to the undersurface of the orifice plate in flooding condition before spinning is started or after all glass fibers are broken. The separating means is characterized by the provision of a clamping means so constructed and arranged as to clamp a mass of molten glass, means for moving said clamping means between a waiting position at which said clamping means will …
