FIELD: production of chemical filaments. SUBSTANCE: apparatus has chute inclined in the direction of filament feeding and provided with transverse walls and conveyance cylinders mounted one above the other. Lower cylinder is positioned in chute. Edges of each transverse wall embrace lower part of conveyance cylinder in spaced relation with respect to it. Liquid supply and discharge branch pipes are positioned at outlet and inlet ends of chute, respectively. Chute is provided with a pair of auxiliary transverse walls. Position of these walls with respect to chute may be regulated so that they may be moved between conveyance cylinder and discharge branch pipe. Transverse wall adjacent to conveyance cylinder and chute bottom define slit with adjustable height. Upper edge if this wall is positioned at the level higher than that of rinsing liquid in chute. Upper edge of other transverse wall is positioned at the level of liquid flow so that its height may be regulated. EFFECT: increased efficiency and improved quality of filaments. 2 dwg
