Abstract

A tandem strip-rolling line has a strip store between the mill so that when the upstream mill is open on the approach of a weld seam joining successive lengths, the downstream mill rolls strip stored in the strip store and conversely when the strip is halted upstream of the second mill, the strip is rolled in the first mill and fed to the strip store.
