Claim:
A method for controlling the coating quantity profile of a paper web wherein the paper web defines a width in a cross direction, and has a narrow-scale coating quantity profile extending over less than 100 mm in the cross direction, the method comprising the steps of: coating the paper web with a coater; after the coater measuring narrow scale coating quantity variations in the paper web to determine a narrow-scale coating quantity of a plurality of narrow strips, each of the narrow strips having a width of less than 100 mm in the cross direction, and having a cross direction position; wherein the plurality of narrow strips have a cross direction sum of said widths amounting to no more than 50% of the paper web width; and controlling the narrow-scale coating quantity profile of the web by controlling the coating of each of said plurality of narrow strips before said dryer by moving one of a plurality of coating nozzles to the cross direction position corresponding to each narrow strip, and discharging a coating from the profiling nozzles on to the web to adjust each of said plurality of narrow strips to a selected coating quantity.
