ABSTRACT:
The invention relates to a method and device for detecting the mass of fiber material (5) which is processed in a rotor spinning machine to form yarn. In order to obtain a measurement signal which is a function of the mass of fiber material and which can also be used for controlling or monitoring a spinning station without requiring an independent measuring device, this measurement signal is detected in the spinning station of a rotor spinning machine on the feed trough (1) thereof.
