Abstract
A bushing plate for use in the production of glass fibers has an array of nozzle tips. Each nozzle tip is formed to have a frusto-conical body with a central aperture. The walls of the nozzle tips have a constant thickness such that the diameter of the central aperture varies over the elongate dimension of the tip. The feature of constant sidewall thickness allows the glass filament size to be selected by trimming the height of the tip such that the appropriate aperture diameter is obtained. The nozzle tips are formed by progressive punching of preformed embossments on a bushing plate.
