FIELD: machine building.
SUBSTANCE: device for sink of bast-fibers material contains pairs of rollers with longitudinal riffles and alternating with these rollers pairs of rollers with co-axial located on shafts and with gap one relative to other disks. Disks by edges allows projections, which are formed by one-sided caving in. Value of gap between disks in each pair of rollers reduces from one edge of rollers from other, and in different with disks of middle clearance between them and value of one-sided caving in reduce lengthwise length of machinery, particularly forward the material.
EFFECT: usage of particular invention provides effectiveness increase of cleaning of fibrous material.
