  • the specification of a winding parameter being lower in said priority order is arranged to be adjusted as a response to a situation in which a sufficient change has not been achieved in said at least one quality indicator by adjusting the specification of a winding parameter upper in said priority order.
  • ranges of variation i.e. the lowest permissible value and the highest permissible value are defined for each winding parameter.
  • the priority order of said winding parameters can be e.g.
  • the web tension r 3 is not adjusted until the controls of the other winding parameters r 2 , r 1 , r 4 and r 5 have not provided a desired result i.e. there is a situation in which the quality indicator differs from its target value and the control measure has set each of said other winding parameters to its lowest or highest permissible value.
  • Said priority order can also be asymmetric such that the position of each winding parameter in said priority order is dependent on the direction of change in the winding parameter in question. For instance, the web tension can be last in said priority order if the web tension should be increased, but first if the web tension should be decreased.
  • the controller apparatus 212 is arranged to adjust specifications of several winding parameters based on at least one quality indicator.
  • Said winding parameters are attached with predetermined weighing coefficients which are arranged to express the ratio of a change in the specification of each winding parameter and a change in said at least one quality indicator.

  • Equation (8) corresponds an example in which the specification of the winding parameter is adjusted on the basis of three determined quality indicators (p, h, WOT).

  • the specifications of the winding parameters are adjusted (block 304).
  • the specifications of the winding parameters can be further adjusted (set) on the basis of control variables given by the operator (block 305).

For example in a situation, in which the variation of the diameter/hardness profile of the machine reel is great i.e.
  • the machine reel is lumpy, whereby air easily remains within the machine reel, it is worthwhile to increase the peripheral force instead of increasing the nip force, because the increase in the nip force would hinder the exit of air from the machine reel and thus would have an undesired effect.
