Abstract:
A control unit maintains the fiber flock column in a feed chute at a set height. The control unit includes a row of light barriers located about a set height for emitting signals in response to interruption of the light barriers by fiber flock. An evaluation unit evaluates the signals to determine the actual height of the flock column and emits a control signal to adjust the feed rollers in the feed chute.
