Abstract
A fiber processing machine includes a first roll having a circumferential surface carrying a first clothing; a second roll having a circumferential surface carrying a second clothing and adjoining the first roll for taking over fiber material carried by the first roll as the first and second rolls rotate; a nip defined between the first and second clothings at a location where the first and second clothings are closest to one another; a bight defined by a generally triangular area immediately adjoining the nip and bounded by an end thereof and by circumferential length portions of the first and second clothings extending away from the nip end; and a cutting edge positioned in the bight and cooperating with one of the rolls for separating impurities from the fiber material as the fiber material is carried past the cutting edge by the roll clothing.
