Abstract:
1. An apparatus for use in connection with a paper machine, comprising at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to: receive, at a moment T receive, at a moment of time T generate a model based on the determined at least one property of the end product and the distribution of at least one property of the sample of the liquid fibre pulp as a function of at least two different particle sizes, wherein the model connects the property of the end product received at the moment of time T receive, at a moment of time T model, at a moment of time T receive information on at least one desired property of the end product, upon detecting that the modeled at least one property of the end product and the at least one desired property of the end product do not match, perform the following: control, on the basis of the generated model, components before the headbox of the paper machine such that the distribution of the at least one property of the liquid fibre pulp in the headbox as a function of different particle sizes is such that it produces the at least one desired property of the end product.
