Abstract / scope

Projection on a screen of the magnified images of the profiles of wool fibre pieces and measurement of their width by means of a graduated scale. The operating technique assures a random sampling of the fibres to be measured. Suitable for wool fibres in any form and also for other fibres of reasonably circular cross-section.
