(c) a second ring having a bore that is disposed within the housing, the second ring having a one end and a second end, either the one end or the second end of the second ring is located adjacent the one end of the ring; and
(d) a sleeve having a bore that is disposed within the housing, the sleeve having a one end and a second end, the second end of the sleeve located adjacent the one end of the second ring wherein the bores of the ring, the second ring and the sleeve are in substantial alignment relative to each other.
2. The apparatus of claim 1 wherein the bore of the ring is tapered.
3. The apparatus of claim 1 wherein a plurality of flexible fingers is provided as an integral component of the second ring.
4. The apparatus of claim 1 wherein the one end of the ring has a beveled edge and the second end of the ring has a flat surface.
5. The apparatus of claim 1 wherein the one end of the second ring has a beveled edge, the second end of the second ring has a recessed portion adapted to receive a beveled edge and a plurality of flexible fingers is provided as an integral component of the second ring.
6. The apparatus of claim 1 wherein the second end of the sleeve has a recessed portion adapted to receive a beveled edge.
7. The apparatus of claim 1 further comprising at least one spacer ring disposed within the housing, the at least one spacer ring having a bore and the at least one spacer ring is located above the sleeve wherein the bore of the at least one spacer ring is in substantial alignment with the bores of the ring, tho second ring and the sleeve.
8. The apparatus of claim 1 wherein the one end of the ring has a beveled edge, the one end of the second ring has a beveled edge and the second end of the second ring has a recessed portion adapted to receive a beveled edge, the second end of the sleeve has a recessed portion adapted to receive a beveled edge, the beveled edge of the ring disposed within the recessed portion of the second ring and the beveled edge of the second ring disposed within the recessed portion of the sleeve.
9. The apparatus of claim 1 wherein the can ends are made of aluminum alloys, steel alloys or other metallic alloys.
10. The apparatus of claim 1 further comprising a plurality of spacer rings disposed within the housing, each of the plurality of spacer rings having bores, at least one spacer ring that located above and below the second ring wherein the bores of the spacer rings are in substantial alignment with the bores of the ring, the second ring and the sleeve.
11. The apparatus of claim 10 wherein the bore of the ring is tapered, a plurality of flexible fingers is provided as an integral component of the second ring arid the one end of the second ring has a lip that is located in between the spacer rings.
12. The apparatus of claim 1 wherein the flange has one or more threaded bores disposed in the flange that are adapted to receive one or more threaded screws.
13. The apparatus of claim 12 further comprising a machine that is affixed to the flange of the housing with threaded screws.
14. The apparatus of claim 13 wherein the machine is selected from the group consisting of a compound liner, a conversion press, a can end seaming apparatus and an offline test apparatus.
15. A method for resisting rotational movement of can ends in a downstacker, the method comprising:
(a) providing a ring with a bore adapted to provide an interference fit between the ring and the can ends; and
(b) restricting the rotational movement of the can ends in the bore of the ring by applying an interference fit between the ring and the can ends,
(c) wherein a plurality of flexible fingers is provided as an integral component of the ring.
16. The method of claim 15 further comprising urging the can ends through the bore of the ring.
17. A method for resisting rotational movement of can ends in a downstacker using an apparatus comprising a housing having a bore with a flange at one end of the housing and a step at a second cad of the housing, a ring having a bore that is disposed within the housing, the ring having one end and a second end, the second end of the ring located adjacent the step of the housing, a second ring having a bore that is disposed within the housing, the second ring having one end and a second end, either the one end or the second end of the second ring is located adjacent the one end of the ring, and a sleeve that is disposed within the housing, the sleeve having one end, a second end and a bore, the second end of the sleeve located adjacent the one end of the second ring wherein the bores of the ring, the second ring and the sleeve are in substantial alignment relative to each other, the method comprising restricting rotation of the van ends in the second ring with an interference fit provided between the second ring and the can ends.
18. The method of claim 17 wherein a plurality of flexible fingers is provided as an integral component of the second ring.
19. The method of claim 17 further comprising urging the can ends through the bore of the second ring.
