Abstract
A method includes steps of: expressing changes of velocity components of a paper material at an exit of a slice lip by using a mathematical model, wherein the changes of velocity components are caused by manipulating an edge flow adjustment means (or a side bleed adjustment means) of a headbox when supplying the paper material on a wire; without changing a velocity component of a flow of the paper material in the mathematical model, setting the mathematical model based on an assumption in which a velocity component orthogonally crossing a flow direction of the paper material is proportionally changed by changes of an edge flow (or a side bleed) of a certain response width from the exit of the slice lip; and conducting a forecasting calculation of changes of a fiber orientation profile in a cross direction by using the mathematical model.
