a packaging material feed unit for a tubular packaging material;
a transporting apparatus for at least one sealing tape and/or sealing elements formed as sealing strips; and
a sealing device by which at least one package is encloseable in at least one sealing region with a sealing element formed as a sealing strip and by which a materially bonded connection of the sealing strip to the package is produced, wherein the sealing device includes a welding device, and wherein the device is configured to seal the packages with sealing elements formed from the same material as the packages so as to produce packages of a single type, wherein the welding device is a U-shaped Sonotrode having two end regions configured to produce ultrasonic welds in the end regions so that two weld seams are simultaneously produced.
