ABSTRACT:
The carding distance (KA) between clothings (14, 15) is scanned using an optical device (22, 26) e.g. using a laser beam (24) from the side of the working area. The measuring value thus obtained can be compared to a pre-set target value in such a manner that the distance mentioned can be adjusted. Card with a controllable actuator system (32, 34) for setting the carding gap between the clothing on the main drum and the clothing on the flats, and with a programmable control system (12) which can influence the actuator system. A sensor system (26, 28) measures the carding gap in order to render regulation of the gap possible. The control system obtains, and processes respectively, data connected with the state of the clothing. The control system (12) is programmed in such a manner that regulation is effected as long as the measuring values supplied by the sensor system appear to be "plausible". If the plausibility no longer is ensured, the control system can deactivate the regulation steps and possibly can itself take over the adjustment process.
