Abstract: A method for controlling a melt-processing installation, wherein the installation has a melt-feed device, a filtering device, and a melt-processing device. Optionally, a melt pump can be used in addition to, or in lieu of, the melt-feed device. A maximum achievable rate of volume change per unit time of a volumetric feed of the melt-feed device and/or of the melt pump is determined, a maximum volume deviation value of the volumetric feed per unit time to the melt-processing device is determined, and a volume change in the filtering device between the melt-feed device and/or the melt pump and the melt-processing device is set such that a resulting rate of volume change of the filtering device is less than, equal to, or slightly larger than the maximum achievable rate of volume change of the melt-feed device and/or of the melt pump so that the maximum volume deviation value is not exceeded.
