Multi-component rotary spinner apparatuses systems and methods for producing fiber from molten material

摘要

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.

主权项

1. A rotary spinner apparatus for producing fibers from molten material comprising:
a hub member extending radially outward relative to a central axis and being rotatable about the central axis; an annular member including a lower wall extending radially outward, a side wall extending axially upward from the lower wall, and an upper wall extending radially inward from the side wall, a first side of the lower wall contacting the hub member, a plurality of apertures being formed in the side wall; a retaining member facing a second side of the lower wall; a plurality of fasteners coupling the retaining member and the hub member, the retaining member, the hub member and the plurality of fasteners structured to limit axial movement of the annular member relative to the hub member and structured to allow radial expansion and contraction of the annular member relative to the hub member; and a slinger member positioned radially inward from the annular member and extending radially outward toward the annular member, the slinger member contacting the hub member; wherein the slinger member contacts the hub member at a second plurality of spaced apart contact areas and is spaced apart from the hub member at a second plurality of gap regions intermediate the second plurality of contact areas.
