This method consists essentially in manufacturing dripper units (4) and attaching them longitudinally to a thread (16) by positioning them at intervals along the latter. For this purpose, the thread (16) is introduced into at least one notch (9) of the dripper unit (4) so as to clamp it. The width of the notch is less than the diameter of the thread. The thread fitted with dripper units is introdu...

The invention relates to a method and device for determining fiber orientation in a paper sample. The surface of the sample (1) is illuminated from an oblique angle (11) by means of more than one light source (2, 3).
