Apparatus and Material6.1 Vettermann Drum Tester (See Fig. 1):6.1.1 Drum, incorporating a revolution counter and fouradjustable retaining

10、segments (thickness: 0.60 6 0.03 in.(15 6 1 mm) on each side wall of the drum. A free-runningcircular brush mounted in such a way that it lightly contacts thesurface of specimens and loose fibers are continuously ex-tracted by a vacuum cleaner. A vulcanized fiber backing sheet93.3 by 10.6 by 0.06 in
