An exemplary bushing system utilizes a bushing having a bottom plate having a plurality of holes from which filaments are drawn, and a plurality of support-receiving elements that are each configured to receive an elongated support. The support-receiving elements extend through the bushing generally along a longitudinal axis. A frame supports the bushing and includes a pair of horizontal rails upon which the supports rest. The horizontal rails comprise a treated surface that permits movement of the elongated supports relative to the frame in the longitudinal direction as the bushing expands and contracts due to thermal heating and cooling.

Transverse row bushings and methods with freedom of movement

A bushing system includes a bushing having a bottom plate with a plurality of holes from which filaments are drawn. At least one elongated support extends through the bushing generally along a longitudinal axis to hold and stabilize the bushing. To handle the harsh conditions under which the bushing is subjected, the support comprises an alumina-based ceramic that generally resists sagging or excessive expansion and contraction during heating and cooling.

A spinner for fiberizing glass has fiberizing holes formed in the spinner sidewall by a process utilizing an electron beam perforating process. A backing material used in the process is deposited on the walls of the fiberizing holes for increasing the corrosion resistance of the fiberizing holes. With regard to the formation of each fiberizing hole, an interaction of the backing material with an electron beam during the electron beam perforating process creates a gaseous backing material that expands through a hole created by the electron beam in the spinner sidewall to eject molten alloy material of the spinner sidewall made molten by the electron beam from the hole and deposit a thin substantially uniform coating layer of the backing material on the wall of the hole to increase the corrosion resistance of the fiberizing hole thus formed.
