Interconnection between two-surface of multi-surface thin strip-shaped layers that lie one on top of the other, in particular, between two strips undergoing a continuous processing

The invention concerns an interconnection of the type specified in the introductory clause of Claim . Coilable strips are continuously processed in sheet rolling mills or in annealing furnaces. They are located in the feed area of the mill in the form of a coil, pass through the mill, and, after they have been processed, they are rewound into a coil at the end of the mill. After the coil on the feed side has been used up, the end of the coil must be interconnected with the lead end of a fresh coil, which is then pulled through the various processing stations in the mill by the end of the first coil, as the latter continues to pass through the mill. At the end of the mill, the two strips can then be detached from one another. The finished strip can then be removed in coiled form, and, when the operation is resumed, the strip being pulled through the mill can be rewound into a coil at the end of the mill. The invention relates to an interconnection between two overlapping end sections of metallic strips () in which a quick and economical interconnetion should be produced. To this end, the invention provides that several annular welds () are provided in the overlapping area () which are situated at a distance from the face ends of both strips ().
