Process and apparatus for the manufacture of discontinuous glass fibers

摘要

The application discloses an apparatus and a process for the manufacture of discontinuous fibers obtained by fluid attenuation. The fibers are attenuated from a bushing whose base is equipped with a substantially continuous plate having a hollowed upper surface of alveoles, said alveoles being perforated with orifices, and whose lower side is cut with grooves defining bosses, each boss being provided with one or several alveoles. The fibers produced are particularly adapted for use in the form of mat, sheet or roving.
