  • Method and apparatus for producing chopped strands
    Patent number: 4537610
    Abstract: Method for producing discrete bundles of filaments includes applying a non-aqueous, hot melt coating material to continuous filaments and gathering the coated continuous filaments into a bundle. The coating material is solidified on the continuous filament bundle so as to establish a first cross-sectional shape and the bundle is then severed into discrete segments whereby the bundle segments are deformed so as to exhibit a second cross-sectional shape at the severed regions. The bundle segments are then heated sufficiently to soften the coating material to permit the bundle segments to substantially return to the first cross-sectional shape.The apparatus of the invention includes a primary applicator for applying a production coating to the filaments and an interim applicator for applying a start-up coating to the filaments.

  • Method for forming glass fibers
    Patent number: 4488891
    Abstract: A glass fiber attenuation apparatus and process wherein molten glass is supplied from a molten glass body to an orifice plate at substantially atmospheric pressure to prevent molten glass flow through an orifice at which attenuation has ceased, thus permitting continuation of the attenuation process despite breakouts at individual orifices. The preferred embodiment of the method includes the steps of cooling the orifice plate undersurface to a non-wetting temperature and delivering molten glass to the orifice plate at a pressure less than the internal, surface tension-generated pressure of any bead formed on the undersurface of the orifice plate upon attenuation cessation at that orifice.
