ABSTRACT:
The average winding diameter of a finite roller band length wound on a supply coil is increased by having the roller band rewound from the supply coil to a storage coil of a larger than the winding diameter, which encloses the supply coil concentrically. During the uncoiling of the band stored on the storage coil for purposes of a continuous manufacturing operation, a welding device is arranged in the annular area between the external diameter of the supply coil and the internal diameter of the storage coil and welds the band trailing end of the storage coil together with the band and leading end of the supply coil. The contents of the supply coil are then taken over by the storage coil, and while this material is uncoiled, a further supply coil is inserted and its leading edge welded to the end of the storage coil.
