Throughout this article it is assumed that the paper structure is isotropic, but most papers produced on papermaking machines such as those based on the principles of the Fourdrinier Machine show a clear anisotropic formation, see also Schaffnit and Dodson (1993), Scharcanski and Dodson (1996, 2000) and Sampson (2009), where the anisotropy of formation is discussed in detail.
