ABSTRACT:
For the optimization of the vacuum output of a suction air installation of a textile machine, the vacuum output is adjustably regulated by initially starting a batch with a predetermined vacuum for the vacuum demands under basic operating conditions and additional fluctuating working conditions, counting the errors which cannot be rectified and the attempts to rectify the errors caused by insufficient vacuum during a predetermined time period, subsequently changing the vacuum output of the suction unit during a subsequent time period, comparing the number of errors occurring under the changed vacuum conditions with the number which had occurred in the previous time period, and increasing the vacuum output when the number of errors exceeds a maximum predetermined amount of errors and decreasing the vacuum output when the number of errors is at or less than the maximum predetermined amount of errors.
