  • Bushing assemblies for fiber forming
    Patent number: 5879427
    Abstract: A bushing assembly for forming fibers from a supply of molten fiberizable material has: (a) a bushing block having an insulating body with a bore extending therethrough and (b) an electrically conductive bushing positioned adjacent to the bushing block to receive molten fiberizable material from the bore. The bushing includes a flange having bonded to an upper surface thereof a primary layer of an electrically insulating material with a bulk density of greater than 2.0 grams per cubic centimeter. The electrically insulating material is positioned adjacent to the liner on the lower surface of the body of the bushing block and is in contact with the molten fiberizable material.

  • Composite bushing design
    Patent number: 4957525
    Abstract: A fiber glass production bushing is described utilizing a flat precious metal plate which is preferably supported by a nonprecious metal support plate. The support plate has slots cut in it so that the rows of depending fiber glass tips can project through it and yet be electrically isolated from the support plate by an air gap. The side and end walls of the bushing are provided by the bushing block located above the tip plate.
