Abstract
An apparatus for resisting rotational movement of can ends in a downstacker is provided, that includes a housing having a bore, a ring having a bore that is disposed within the housing, a second ring having a bore that is disposed within the housing and a sleeve having a bore that is disposed within the housing wherein the bores of the ring, the second ring and the sleeve are in substantial alignment relative to each other. A method of resisting the rotational movement of can ends in a downstacker is also provided.
Claims19
An apparatus for resisting rotational movement of can ends in a downstacker, the apparatus comprising:
- (a) a housing having a bore for receiving the can ends with a flange at one end of the housing and a step at a second end of the housing;
- (b) a ring having a bore that is disposed within the housing, the ring having a one end and a second end, the second end of the ring located adjacent the step of the housing;
- (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.
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.
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.
