  • Fiberizing apparatus
    Patent number: 7434421
    Abstract: A fiberizing apparatus for converting molten material into continuous fibers has an internal support structure to minimize high temperature creep and sagging of a tip plate, the reinforcing structure forming at least about 16 internal cells and the hole pattern in a bushing screen is engineered such that the hole area in each screen area above each of the at least 16 cells controls the amount of molten material flowing into each cell to produce a substantially improved tip plate temperature profile and fiberizing efficiency.
