A processing plant for metal strips (1) has a welding machine, a strip store downstream of the welding machine and a processing device downstream of the strip store. The metal strips are welded to form a continuous strip with the welding machine, which is stored in the strip store and output from there to the processing device. The metal strips are connected via diagonally extending weld seams. To join the weld seams, first the strip head (2) and the strip foot (3) of the metal strips are twisted and the two strips are connected by forming the weld seam. The weld seam extends only transversely to the transport direction (x) during the welding process. Finally, the strip head and the strip foot of the metal strips are twisted back again. As a result, the weld seam now extends diagonally to the transport direction (x).

Systems and methods of non-contact tensioning of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor. The magnetic rotor is spaced apart from the metal strip by a first distance. The systems and methods also include tensioning the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is tensioned in an upstream direction or a downstream direction. In other aspects, rotating the magnetic rotor induces a magnetic field into the metal strip such that a force normal to a surface of the metal strip is applied to the metal strip.

Systems and methods of pre-ageing of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor of a reheater. The systems and methods also include heating the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is heated.
