Abstract
Rotary spinner apparatuses, systems and methods for producing fibers from molten materials are disclosed. Certain exemplary embodiments include rotary spinners including a hub, a slinger, an annular member, a retaining member, and a plurality of fasteners. In certain embodiments the hub, the retaining member, and the plurality of fasteners are structured to limit axial movement of the annular member relative to the hub member and to allow radial expansion and contraction of the annular member relative to the hub member. In certain embodiments the annular member is structured to contact the hub at a plurality of contact areas and is spaced apart from the hub at a plurality of gap areas. In certain embodiments the slinger is structured to contact the hub at a plurality of contact areas and is spaced apart from the hub at a plurality of gap areas.
