<p>A belt roller has a sensor (16) which comprises a sensor lever (20), a belt coil (14), and a ganged control lever (18) which is coupled via a friction coupling to the belt coil (14), and in which the ganged control lever (18) is adjustable between an output position, in which the sensor lever (20) is blocked, and an extraction position, in which the sensor lever (20) is released. An independent claim is included for a method of operating a belt roller with belt coil and sensor lever.</p> |
