ABSTRACT This invention relates to a screen device for separating undesir- able impurities from a pulp suspension. The screen device is provided with at least one continuous circular screen slot provided between a first chamber into which unfiltered suspension is conducted through an inject- inlet and from which undesirable material is passed away through a reject- outlet. There is a second chamber, from which screened pulp suspension is transported through an accept-outlet. According to the invention the screen slot is formed by two walls which are stationary in relation to each other and a cleaning device in the form of a doctor or knife bears against the screen slot, said device and slot being movable in relation to each other for continuous cleaning of the screen slot, Owing to this particles jammed in the screen slot are removed very effectively. The rotation of the cleaning device or those walls forming the slot for most pulp suspensions may be made rather slow and therefore a screen of this type will not require great power.
