DEVICE FOR CONNECTING MATERIAL SHEETS

Disclosed is an apparatus for joining an expiring old, metal-containing web with a tapered new, metal-containing web, with an assembly of two segments forming a gap to the receiving an arrangement ofsuperimposed, to be joined material webs, spaced from each other and each having an end face, wherein at least one of the segments movably mounted and can be moved into a working position, in the itsend face is opposite the end face of the other segment at a minimum distance, including the arrangement of material webs to be joined, drive means for moving the at least one segment, an electric welding device, wherein the end face of the one segment with the first electrode assembly and the end face of the other segment is provided with the second electrode assembly and the electric welding device is formed, in the working position of the segments a welding process for connecting the material webs, and a control device which is designed to control the drive device such that the at least onemovably mounted segment is brought into the working position and then the at least one movably mounted segment from the working position will get removed.
