<p>The invention relates to a method and a lubricant application device (100) for regulating the planarity and/or roughness of a metal strip (400) in the run-out of a cold rolling stand by suitable metering of the amount of at least one lubricant per unit of time applied to the metal strip (400) in the run-in of the cold rolling stand. To further improve the quality of cold-rolled metal strip with regard to its planarity and/or roughness, it is proposed according to the invention that the applied amount of lubricant is metered in the form of a distribution of the quantity over the width of the metal strip per unit of time in accordance with an established deviation between an actual planarity distribution and a set planarity distribution over the width of the metal strip in the run-out of the cold rolling stand or a deviation between an actual roughness distribution and a set roughness distribution over the width of the metal strip in the run-out of the cold rolling stand (100) or a combination of the two deviations.</p> |
