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.
