<p>The device has a transmission clutch (1) with a gear wheel (3) that rotates with a winding shaft. The gear wheel is directly or indirectly contacted with another gear wheel (2) that is rotated with a drive shaft. Two signal generators (5, 6) are attached to the gear wheels and adapted for delivering periodic signals (11, 12) that are correlated with rotating motion of the respective gear wheels. Sensors (7, 8) detect a relative change of local position or the temporal sequence of the signals from the signal generators.</p> |
