ABSTRACT:
A spinner and a distributor spinner cup fixedly nested within the spinner are adapted to receive two molten thermoplastic materials of different coefficients of thermal expansion to produce a dual-component glass fiber insulation product. The inside wall of the spinner peripheral side wall is adapted to receive, through horizontal slots adjacently vertically disposed, first and second molten thermoplastic materials and centrifuge same into horizontal annular non-interrupted circumferential cavities disposed above and below one another. Passages lead from exit orifices in each cavity outwardly at differing angles. Passages from first and second thermoplastic material cavities join with one another at orifices on an outer side of the peripheral side wall.
