Fibre orientation In machine-made papers there are more fibres aligned in the machine direction than perpendicular to it. Fibre orientation refers to this anisotropy in the structure of paper. This section explains the basic mechanisms leading to anisotropic fibre orientation on the paper machine, discusses the nature of fibre orientation, and explains measurement. The technical
