ABSTRACT:
A multiple segment glass fiberizing spinner and method of making same provides a product of low cost and improved service life. The spinner comprises a plurality of, preferably four, segments of a cast alloy having a large number of small radially oriented apertures disposed about its periphery. Each segment is preferably investment cast. After casting, the segments may be trued if necessary by heating and forming. The segments are then weighed and same-weight segments are welded end-to-end to form a hoop or annulus. Next, a larger plurality of small bores are formed in the sidewall of the spinner. Finally, an optional bottom disc is secured to the segmented annulus, preferably by welding.
