ABSTRACT:
An apparatus for regulating fiber quantities supplied to a textile machine as a fiber layer, comprises a sensor device for mechanically sensing thickness variations of the fiber layer at a plurality of locations along the layer width and emitting individual mechanical signals representing the magnitude of thickness variations at each location, a transducer arrangement connected to the sensor device for converting each individual mechanical signal into an individual electric signal, a signal adder connected to the transducer arrangement for combining the individual signals into a joint electric signal, a regulator arrangement connected to the signal adder for comparing the joint electric signal representing an actual value with a predetermined desired value of fiber layer thickness for generating a setting signal, a fiber layer delivery device, and a setting device connected to the regulator arrangement and the fiber layer delivery device for controlling the setting device by the setting signals, whereby fiber quantities of the fiber layer are regulated as a function of the thickness variations of the fiber layer.
