<p>The tension device comprises a rotor (10), a rotor disk (12), a covering disk (4) and a counter disk (7). The compressed air is supplied to a material feeder by a compressed air-supply connection (2). A counter pressure develops in the compressed air-supply connection by supplying a material in the material feeder. The rotor disks, the covering disk and the counter disk are pressed together in a partial area by a pressure element (20) depending on the counter pressure. The compressed air is directly supplied to the pressure element which is controlled by a measuring and controlling device.</p> |
