A method and apparatus for making paper by refining fibrous stock. The stock is passed through an adjustable refining means and a sample of the refined stock is analyzed using a fibre fineness distribution analyzer to produce, over a range of fibre widths, counts of the number of fibres in the sample which have a selected fibre width. Fibre width is plotted against fibre count at intervals of 1 mu m over the range of from 7 mu m to 64 mu m to obtain a fibre fineness distribution curve. The fibre fineness distribution curve is compared with a reference fibre fineness distribution curve obtained by the prior analysis of stock known to have produced paper of desired quality. The refining means is then adjusted to produce a stock the analysis of which produces a distribution curve substantially the same as the reference curve. |
