ABSTRACT:
The invention relates to a method and an equipment for defining the cross-directional properties of a sheet in a continuous sheet making process. According to the invention, the set point profile of the actuators affecting the cross-directional properties of the sheet is defined, high frequencies are filtered from the defined profile, and shrinkage nonlinearity is deduced from the filtered profile without modulating or stimulating the actuators.
