THE METHOD OF TREATING DISCOUNTINUOUS TEXTILE FIBERS PREPARATORY TO REMOVING FOREIGN BODIES THEREFROM COMPRISING FORMING THE MINGLED FIBERS AND FOREIGN BODIES INTO A COHERENT WEB OF THE CHARACTER OF A WEB NORMALLY PRODUCED BY A CARDING MACHINE, SAID WEB BEING A PLURALITY OF FIBERS IN THICKNESS, ADVANCING THE WEB AT A PREDETERMINED SPEED, CAUSING THE FIBERS TO CLING TO A SURFACE IN THE PRESENCE OF MOISTUER, ADVANCING SAID SURFACE AT A GREATER SURFACE SPEED THAN THE SURFACE SPEED OF THE WEB. WHEREBY THE FIBERS CLINGING TO SAID SURFACE ARE FORMED INTO A FILM OF SUBSTANTIALLY SINGLE FIBER THICKNESS WHEREIN THE MAJORITY AT LEAST OF THE FIBERS ARE SEPARATED LATERALLY FROM EACH OTHER AND EXTEND IN A DIRECTION PREDOMINANTLY PARALLEL TO THE DIRECTION OF MOVEMENT OF SAID SURFACE, ADVANCING THE FILM ON SAID SURFACE AND SUBJECTING THE FILM TO THE PRESSURE OF A RIGID MEMBER AGAINST SAID SURFACE, WHEREBY MANY OF THE FOREIGN BODIES ARE DISINTEGRATED INTO FRAGMENTS.
