Abstract
A process is described for producing substantially continuous cuts or coils for tab or shell manufacture. A coil of aluminum alloy is split into at least first and second cut coils, each of the first and second cut coils having a cut strip width less than a width of the aluminum alloy coil, and the free ends of the cut strip coiled on the first and second coils are connected to form a continuous cut strip having a length longer than a length of the strip on the aluminum alloy coil.
Claims21
A process, comprising:
- splitting a coil of aluminum alloy into at least first and second cut coils, each of the first and second cut coils having a cut strip width less than a width of the aluminum alloy coil;
- and
- connecting free ends of the cut strip coiled on the first and second coils to form a continuous cut strip having a length longer than a length of the strip on the aluminum alloy coil.
A continuous cut strip having first and second strip ends welded together and being coiled on first and second coils, wherein the first and second coils are stacked one-on-top-of-the-other and separated by a spacer, and wherein the length of the continuous cut strip is at least about 150% of the length of the strip on the aluminum alloy coil.
A continuous cut strip having first and second strip ends welded together, wherein the continuous cut strip is coiled on a common coil, wherein the coil is staggered back-and-forth across a face of a rewind mandrel, and wherein the length of the continuous cut strip is at least about 150% of the length of the strip on the aluminum alloy coil.
A system for manufacturing can ends, comprising
- a splitter to cut an aluminum alloy coil into first and second cut coils, each of the first and second cut coils having a width less than a width of the aluminum alloy coil;
- an entry mandrel to receive the first and second cut coils;
- and
- a welder to connect an inner diameter end of the first cut coil to an outer diameter end of the second cut coil.
