<p>A spinner for centrifuging molten glass into glass fibers comprises a spinner peripheral wall having orifices for forming mineral fibers, and an annular spinner bottom wall defining an open bore, the bottom wall being connected at its outer periphery to the peripheral wall and adapted to receive a stream of molten glass, a central hub, and spoke members connecting the hub and the bottom wall to enable rotational force to be transferred from the hub to the peripheral wall, the spoke members enabling a substantial flow of air downwardly through the bore.</p> |
