ABSTRACT:
A tensioning device for a packaging tape, which is slung around a stack of goods in a packaging station and of which the free end is held there, has a driving plate drivable by a motor around an axis of rotation with a bearing surface for the tape. Clamping elements each having a clamping surface are associated with the driving plate. At least one guiding element is provided for the clamping elements, by means of which, in a closing area smaller than the surrounding angle of the tape around the bearing surface, the clamping elements can be brought into a position, in which the tape is non-positively held between the clamping surfaces and the bearing surface.
