ABSTRACT:
An apparatus for sorting fibers and separating them into fractions with desirable and undesirable properties comprises a housing provided with a first chamber; a device for introducing fibers to be sorted into the first chamber; a rotary element revolvably supported in the first chamber and provided with a mechanism for receiving the fibers and applying a fast rotary movement thereto; a multiplicity of material-receiving channels leading from the first chamber, a first one of which is provided with a first window adjacent to the rotary element for the reception of trash of relatively greater mass than the remaining material, a second one of which is provided with a second window for the reception of nep and undesirable fibers of intermediate mass and one of which is provided with a third window adjacent to the rotary element for the reception of desired fibers; the channels being in fluid communication with an air pressure source; wherein the fast rotary movement results in a centrifugal force, which in combination with the degree of air pressure applied in each of the material-receiving channels causes separation of trash of greater mass than the remaining material as well as the separation of nep and undesirable fibers from good quality fibers.
