  • the present invention relates to a method for rapidly joining a ribbon end of a metal strip undergoing a processing process, unwound from a coil, to the beginning of the strip unwound from a next coil to form a locally determined but arbitrarily contoured cutting line. Furthermore, the present invention relates to a device for rapidly connecting a ban end Dendes with a strip beginning to produce a location-specific, but arbitrarily contoured cutting or connecting line, which is particularly suitable for performing the method for quick connection.
