ABSTRACT:
Apparatus and a process for the high-speed coiling of an aluminum strip. The high speed coiling can be accomplished throughout a continuous casting process without slowing the coiling as the present invention enables the transfer of the moving strip from one coil to an empty mandrel without slowing the line speed. Since line speeds can be approximately 3600 feet per minute, this represents an advance in process technology. Generally, the transfer of the moving strip is accomplished using a very high speed knife, and a belt wrapper. The moving strip is accumulated on one mandrel to form a coil, the coil is moved away from the knife and a second mandrel is brought into position. The knife is positioned at the moving aluminum strip and accelerated to cut the strip and deflect it to a tucking roll with a moving belt. The moving strip is forced around the second mandrel and starts to wind to form a coil. The completed coil is removed and the process is repeated.
