A fiberizing apparatus for converting molten material into continuous fibers having an improved internal support structure to minimize high temperature creep and sagging of the tip plate or orifice plate is disclosed. The preferred internal support structure is welded to the sidewalls and the top surface of the tip plate and is comprised of a plurality of internal intersecting supports that form a diamond shaped structure. A method of fiberizing a molten material using the fiberizing apparatus is also disclosed.
An apparatus is provided for producing continuous glass filaments. The apparatus comprises a feeder (20) for supplying streams of molten glass to be drawn into continuous filaments, a drawing device (40) adapted to draw the streams into the filaments, and heat removal apparatus (50) located adjacent to the feeder for transferring energy in the form of heat away from a filament forming area adjacent to the feeder. The heat removal apparatus includes first and second manifolds (52a, 54) through which a cooling fluid circulates, a plurality of fins (56) having first and second ends (56a and 56b) and interface material (58). The first ends of the fins are associated with the first manifold and the second ends are positioned adjacent to the second manifold. The first ends may be fixedly connected to the first manifold. The interface material is interposed between the second manifold and the second ends to provide a path for energy in the form of heat to flow from the fins to the second manifold.
An apparatus (10) is provided for producing continuous glass filaments (30). The apparatus (10) comprises a bushing (20) for supplying streams of molten glass and a drawing device (40) adapted to draw the streams into continuous glass filaments (30). A cooling device (50) is also provided and is located adjacent to the bushing (20) for drawing in heated air from a filament forming area beneath the bushing such that heat is convectively transferred away from the filament forming area.
