Method and arrangement for welding together the ends of rolled strips of finite lengths to form a strip of an infinite length during further processing of the strip

摘要

The mean winding diameter of the finite length of rolled strip wound on a supply coil is increased in that the rolled strip is wound from the supply coil onto a larger average winding diameter concentrically surrounding the storage coil and during the duration of the unwinding of the strip stored on the storage coil for the purpose of its continuous further processing Annular space between the outside diameter of the storage coil and the inside diameter of the storage coil welding device welds the end of the storage coil to the beginning of the storage coil, the contents of the storage coil are then taken over by the storage coil and a further storage coil is introduced during its processing and its beginning at the end of the Storage coils is welded.
