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 (28), and a belt wrapper (24). The moving strip is accumulated on one mandrel (2) to form a coil, the coil is moved away from the knife and a second mandrel (4) 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.

L'invention concerne un appareil et un procédé d'enroulement à grande vitesse d'une bande d'aluminium. On peut effectuer l'enroulement à grande vitesse par un procédé de moulage en continu sans ralentissement de l'enroulement, la présente invention permettant le transfert de la bande mobile d'une bobine à un mandrin vide sans ralentissement de la vitesse de ligne. Etant donné que les vitesses de ligne peuvent être d'environ 3600 pieds par minute, cela représente un progrès dans la technologie des procédés. En général, le transfert de la bande mobile s'effectue au moyen d'une lame (28) à très grande vitesse et d'un emballeur de courroie (24). On dispose la bande mobile sur un mandrin (2) où elle forme une bobine qui est placée loin de la lame et on met en place un deuxième mandrin (4). On dispose la lame sur la bande d'aluminium mobile et on l'accélère pour couper la bande et la dévier vers un cylindre de serrage à courroie mobile. On force la bande mobile autour du deuxième mandrin où elle commence à s'enrouler pour former une bobine. On retire la bobine entière et on recommence le procédé.
