Abstract
Apparatus and method of producing glass fibers employing a tipped or tipless annular bushing plate from which fibers are drawn as an annular array. A cooling gas, such as air, is directed into contact with the bushing plate and with either, or both, the exterior and interior of the annular array.
Claims12
A glass fiber-forming bushing comprising an annular orificed bushing plate, a center portion positioned within the annular plate and at least one port opening from said center portion into a manifold and at least one port opening from said manifold.
A glass fiber-forming bushing comprising an annular orificed bushing plate, a center portion positioned within the annular plate, at least one port opening from said center portion to the exterior of said bushing, a first manifold positioned in spaced relationship to said bushing and adapted to discharge gas into contact with said bushing plate and a second manifold positioned intermediate said bushing plate and said first manifold and adapted to withdraw gas along said bushing plate.
A method of producing glass fibers which comprises drawing glass fibers as an annular array from an annular bushing having a center portion positioned within an annular portion of said bushing, introducing a gas into contact with the outer periphery of said annular array, and drawing said gas through said array and through a center portion of said bushing.
A method of producing glass fibers which comprises drawing glass fibers as an annular array from an annular bushing having a center portion positioned within an annular portion of said bushing, introducing a gas into contact with the inner periphery of said array and withdrawing said gas through a center portion of said bushing.
A method of producing glass fibers which comprises drawing glass fibers as an annular array from an annular bushing having a center portion positioned with an annular portion of said bushing, introducing a gas into contact with the outer periphery of said array and into the annular portion of said bushing and withdrawing a first portion of the gas through the center portion of said bushing and withdrawing a second portion of the gas from within said annular array from a locus between the point of introduction of said gas and the face of said bushing.
