Zusammenfassung:	FIELD: purification of waste water from solid refuse, rake-type devices in particular. ^ SUBSTANCE: proposed device has frame with filtering cloth, rake with teeth secured on two endless chains mounted on drive and working gear wheels. Filtering cloth is made in form of set of flexible thin strips secured in lower cross-member of frame by one end and other end provided with stepped tenons is received by seats of upper cross-member. Rake teeth points are located in plane of their motion and working surface of filtering cloth is mounted at angle relative to it. Seats are formed by stepped projections and slots of inserts of upper cross-member. ^ EFFECT: enhanced efficiency and reliability of device due to exclusion of connecting strip from filtering cloth and due to their self-cleaning. ^ 3 cl, 7 dwg, 1 tbl
