METHOD FOR THE CONTROL OF THE TRANSVERSE PROFILES OF A WEB

A method for controlling transverse profiles of a web in a web-manufacturing machine, such as a board or paper machine, and/or being treated in a finishing machine. At least one of a transverse caliper, grammage and moisture profiles of the web is measured either directly or indirectly. Actuators ac...

Zusammenfassung:	A method for controlling transverse profiles of a web in a web-manufacturing machine, such as a board or paper machine, and/or being treated in a finishing machine. At least one of a transverse caliper, grammage and moisture profiles of the web is measured either directly or indirectly. Actuators acting upon these profiles are regulated by measurement signals. In order to optimize the quality of the web to be produced, the reel formation, and the runnability of the machine, the transverse tension profile of the web to be manufactured and/or treated is measured. Based on the measurement of the transverse tension profile, set profiles are formed which control the actuator(s) of the profile regulation.
