Abstract

Apparatus for manufacturing mineral fibers from a mineral melt. Two groups of spinner wheels are arranged symmetrically with respect to each other. Each group includes a primary spinner wheel which receives molten mineral and a secondary spinner wheel to which material is transferred from the primary spinner wheel. The wheels in each group are rotated on horizontal axes in opposite directions and the secondary spinner wheels are rotated in a direction such that at the place where they are closest to one another, the peripheral motion of each is upward. An air stream is directed horizontally and generally axially of the spinner wheels such that it sweeps over the peripheral surfaces of the spinner wheels for transferring fibers to a fiber collection surface.
