(57) Abstract: The invention concerns a control method for such an applicator and metering unit in which the coating mix is applied onto the web via a gap formed between the web and a blade tilted to an acute angle to the web, and the applied coating mix is smoothed and the excess mix is removed at the doctor blade. The invention is based on controlling the final coat weight by way of altering the amount of coating mix adhering to the web at the applicator unit. According to the method the linear loading pressure of the applicator unit blade (12) is at the start-up set to an approxi- mately correct value for desired coat weight and held at a constant level during running, and the amount of coating mix applied onto the web is controlled during running by altering the amount of coating mix adhering to the web at the applicator unit (2). This arrangement achieves an accurate control of coat weight and the cross-directional profile of coat weight be readily controlled. (Figure 1)
