ABSTRACT:
A spinner is adapted to produce a dual glass curly fiber component and a single straight glass fiber component insulation product. The spinner includes a plurality of horizontal channels within the spinner peripheral wall. The channels separate two molten glasses of differing coefficients of thermal expansion from one another which emerge outwardly together as a dual glass curly fiber. In other portions of the spinner peripheral wall a plurality of horizontal channels carry single molten glass which emerges as straight glass fibers. The spinner provides mechanical strength and resistance to reduce deformation of said spinner as well as creating a fiber glass product with stability, compressibility and expendability.
