A foil processing device comprises at least two supply units for supplying at least two foils for processing, a processing unit for processing the at least two foils to each other and a transport unit for transporting the foils from the supply unit to the processing unit. At least one of the foils is segmented comprising mechanically weak zones separating subsequent foil segments for enabling real-time correction of a relative position between the foils. The transport unit includes at least two support members for supporting at least two subsequent segments of the segmented foil.
