The invention provides an apparatus for cleaning fibers by means of revolving rollers, the fiber mass being divided, expanded, and recombined while being successively transferred over at least three rollers, the outer surface of at least one of the rollers revolving in close proximity to, but spaced apart from, the other rollers, to form a substantially triangular enclosure therebetween, the apparatus including a first roller, driven at peripheral speed faster than the remaining rollers, arranged as a moving source of fiber supply at the beginning of the process and to receive and card fibers from the third of the rollers; a second, condenser roller, driven at a peripheral speed slower than the first roller, arranged to receive at least a part of the fiber mass from the first roller and to transport the fibers to the third roller; a third, opening roller, driven at a peripheral speed relatively slower than the first roller, arranged to receive fibers from the condenser roller and to transport the fibers back to the first roller; and a stationary fiber stream separator body positioned within the triangular enclosure, the body being of substantially triangular cross-section, for directing fiber streams and preventing turbulent interaction between the streams within the substantially triangular enclosure.

Apparatus for cleaning fibers

The invention provides apparatus for cleaning fibers by a combination of revolving rollers, including a first roller arranged to hold and collect fibers from a supply source, a second roller arranged to take off fibers from said first roller, a third roller driven faster than either of the first or second rollers and arranged to receive, expand, card and eject fibers from the second roller. At least one of the first or second rollers is provided, over the entire surface thereof, with a plurality of pointed, toothlike projections, a first quantity of the projections pointing in the direction of rotation of the roller and a second quantity of the projections pointing in the direction opposite to the direction of rotation of the roller. A fiber mass to be cleaned is divided, expanded and recombined while being successively transferred over the three rollers.
