Abstract
An instrument for separating out any one or more of the components of any given sample of fluff. The instrument includes a base having an annular opening formed in its upper surface. A spindle is journaled in the base, and supports a sieve and enclosure over itself. A compressed air bar is located between the sieve and the spindle, to allow compressed air to escape through the sieve and impact on the fluff sample in the enclosure. A motor is provided to turn the chamber, sieve and enclosure while the air bar is held stationary. The motor turns the spindle by any suitable arrangement such as belt drive, rim drive, direct drive or any other appropriate arrangement. A vacuum motor and assembly communicates with the annular base opening to draw components to be separated from the sample through the sieve, spindle and base, leaving only the remaining components in the enclosure above the sieve. These components are compared to determine the quality of the fluff sample.
