Abstract
The invention relates to a method and system for improving the application of a coating on a Yankee cylinder (CR) in tissue paper machines. The invention implements a moisture-controlled environment () in an area of the exposed Yankee cylinder between the take-off position (TO) and ahead of the transfer position (TP) of the web, i.e. before and/or after the application of a coating with Performance Enhancing Material (PEM), wherein the cooling effect on the Yankee surface is increased by increased evaporation rate of water in the coating or water additionally applied onto the coating.
