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.

First claim

What is claimed is:

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.

2. The apparatus of claim 1 further comprising:
a shaft coupled with the hub member, the shaft extending along and being rotatable about the central axis;
a dispensing member structured to direct a stream of molten material in a downward direction to contact the slinger member; and
a plenum structured to direct a stream of elevated temperature gas toward an exterior surface of the annular member.

3. The apparatus of claim 1 wherein the first side of the lower wall contacts the hub member at a plurality of contact areas and is spaced apart from, the hub member at a plurality of gap regions intermediate the plurality of contact areas.

4. The apparatus of claim 3 wherein the plurality of gap regions are provided by recesses defined in the hub member.

5. The apparatus of claim 1 wherein the plurality of fasteners are positioned to extend through a respective plurality of recesses defined in an inner periphery of the lower wall.

6. The apparatus of claim 1 wherein the retaining member and the hub member apply a clamping force on the lower wall of the annular member.

7. The apparatus of claim 1 wherein the annular member comprises a plurality of gussets extending radially inward from the side wall and axially upward from the lower wall to the upper wall.

8. 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 second plurality of gap regions are provided by recesses defined in the slinger member.

9. The apparatus of claim 8 further comprising:
a shaft coupled with the hub member, the shaft extending along and being rotatable about the central axis;
a dispensing member structured to direct a stream of molten material in a downward direction to contact the slinger member; and
a plenum structured to direct a stream of elevated temperature gas toward an exterior surface of the annular member.

10. The apparatus of claim 8 wherein the first side of the lower wall contacts the hub member at a plurality of contact areas and is spaced apart from the hub member at a plurality of gap regions intermediate the plurality of contact areas.

11. The apparatus of claim 10 wherein the plurality of gap regions are provided by recesses defined in the hub member.

12. The apparatus of claim 8 wherein the plurality of fasteners are positioned to extend through a respective plurality of recesses defined in an inner periphery of the lower wall.

13. The apparatus of claim 8 wherein the retaining member and the hub member apply a clamping force on the lower wall of the annular member.

14. The apparatus of claim 8 wherein the annular member comprises a plurality of gussets extending radially inward from the side wall and axially upward from the lower wall to the upper wall.
