ABSTRACT:
A tensioning device for attraction mechanism including a receiving and mounting housing, a roller carrier pivotably connected to the mounting housing, a bearing which radially supports the roller carrier relative to the mounting housing, a spring between the roller carrier and the mounting housing for applying a tensioning force, and a damping device. The damping device includes a damping bush which, by friction, dampens any movement between the roller carrier and the mounting housing in such a way that damping is greater in the direction of an increasing tension force than in the direction of decreasing tension force. A flat band spring applies the friction force to the damping bush. The flat band spring is secured, at a first end, to the receiving and mounting housing in a rotationally fast way, and at a second end to the damping bush in a rotationally fast way.
