Abstract: The invention relates to a strapping device, in particular a mobile strapping device, for strapping packaged products using a strap, said device having a tensioning device for applying tension to a loop of a strapping band and being provided with a tensioning gear that can be motor driven to rotate about a tensioning axis. The tensioning device also has a tensioning plate that co-operates with the tensioning gear and the tensioning gear and/or the tensioning plate is or are located on a rocker that can be motor-driven to pivot about a rocker access, in order to increase or decrease the distance between the tensioning gear and the tensioning plate by means of a pivoting motion of the rocker. An aim of the invention is to achieve a high functional reliability in a strapping device of this type.

Abstract: In a method to seal/lock a strap (44) including a metal strap (44d) which is fitted at least in the zone of seal with a protective layer (44c), the packing strap is laid in the form of a loop around the package and is held, in particular, clamped, in place before and/or during production of the seal. The seal is implemented on the packing strap (44) by resistance welding and the protective layer (44c) of the packing strap (44) shall be pierced before and/or during production of the seal.
