Abstract
Abstract An automatic coating and printing machine wherein can bodies and like tubular members are automatically positioned on mandrels and thereafter serially presented to coating and printing blankets wherein the necessary coating and printing is effected thereon with the mandrels being rotated as the can bodies carried thereby contact the blankets of the coating and printing cylinders to transfer coating and printing materials to the can bodies. Thereafter, the appropriately coated and printed can bodies are automatically transferred from the mandrels to another conveyor. The mandrels are so mounted wherein when no can body is on a mandrel, the mandrel does not come into contact with the printing or coating blankets.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
An apparatus for performing an operation on a thin wall tubular member comprising a working member, a conveyor having a first support thereon particularly adapted for supporting a thin wall tubular member in telescoped relation and presenting the tubular member to said working member, means for resiliently urging said first support away from said working member to prevent engagement of said working member by said first support in the absence of a tubular member, and a second support opposing said first support and movable therewith, said second support having a tapered support surface for engaging the tubular member, and aligning said first support with said second support and overcoming the urging of said first support.
Claim 2
Independent Claim
115 words
An apparatus for performing an operation on a thin wall tubular member comprising a working member, a conveyor having a first support thereon particularly adapted for supporting a thin wall tubular member in telescoped relation and presenting the tubular member to said working member, means for resiliently urging said first support away from said working member to prevent engagement of said working member by said first support in the absence of a tubular member, and a second support opposing said first support and movable therewith, said second support having a tapered support surface for engaging the tubular member, and aligning said first support with said second support and overcoming the urging of said first support.
Claim 3
Independent Claim
146 words
An apparatus for externally coating a can body comprising a coating drum rotatable about an axis, an endless conveyor mounted for movement in part about said axis, a mandrel carried by said conveyor in cantilever relation for movement concentric to and closely adjacent to said drum, and a support mounted for movement about said axis in opposed relation to said mandrel, said support having an end axially spaced from said mandrel in all positions thereof and configurated for interlocking engagement with an end of a can body to aid said mandrel in supporting a can body, means for resiliently twisting said conveyor to urge said mandrel slightly away from said drum in the absence of a can body, and said configurated support end being tapered for automatically shifting said mandrel to a position parallel to said axis when a can body is carried by said mandrel.
Claim 4
Independent Claim
146 words
An apparatus for externally coating a can body comprising a coating drum rotatable about an axis, an endless conveyor mounted for movement in part about said axis, a mandrel carried by said conveyor in cantilever relation for movement concentric to and closely adjacent to said drum, and a support mounted for movement about said axis in opposed relation to said mandrel, said support having an end axially spaced from said mandrel in all positions thereof and configurated for interlocking engagement with an end of a can body to aid said mandrel in supporting a can body, means for resiliently twisting said conveyor to urge said mandrel slightly away from said drum in the absence of a can body, and said configurated support end being tapered for automatically shifting said mandrel to a position parallel to said axis when a can body is carried by said mandrel.
Claim 5
Dependent Claim
31 words
The apparatus of claim 2 wherein said conveyor passes around a sprocket mounted for rotation about said axis, and said means for resiliently twisting said conveyor being carried by said sprocket.
