Abstract

A first steel strip and a second steel strip () are rolled in succession in at least one roll stand () of a cold rolling mill. A rolling pause, in which no steel strip is rolled, is provided between the rolling of the first and the second steel strip (). The first steel strip is fed over a first path starting from a first pay-off reel (), and the second steel strip () is fed over a second path starting from the first pay-off reel (), or from a second pay-off reel different from the first pay-off reel (). The first steel strip is not heated as it is fed to the rolling mill (), whereas, by contrast, the second steel strip () is heated. The second path is longer than the first path.
