1. Kontinuerligt filtreringsförfarande, vid vilket förfarande an-vänds en rörlig ändlös filterduk (1) eller motsvarande, pä vilken suspensionen (3) som skall filtreras mätäs vid en bestämd matnings-station (2) och frän vilken den bildade kakan (6) av fast material avlägsnas vid en bestämd, i dukens rörelseriktning efterföljande avlägsningsstation (5), kännetecknat därav, att suspensionen (3) mätäs pä den i rörelse varande filterduken (1) vid tvä olika matningsstationer (2) sä, att suspensionen vid dessa stationer kommer pii olika sidor av duken, varvid vätskan som filtreras genom duken rengör den frän fast ämne, som inte lösgjorts vid respektive föregäende avlägsningsstation (5),
2. Filtreringsförfarande enligt patentkravet lf kännetecknat därav, att suspensionen (3) pressas mellan matningssta- tionen (2) och avlägsningsstationen (5) medelst ett i riktning med filterduken (1) löpande pressband (8).
3. Filtreringsförfarande enligt patentkravet 1, kännetecknat därav, att suspensionen (3) pressas mellan matningsstati- onen (2) och avlägsningsstationen (5) medelst valsar (12), vilka böjer filterduken (1) tili päsform.
4. Filtreringsanordning avsedd för tillämpning av ett filtreringsförfarande enligt nägot av ovanstäende patentkrav och omfattande en rörlig, ändlös filterduk (1), organ (4) för matning av suspensionen (3) som skall filtreras pä duken vid en bestämd matnings-station (2) samt organ (7) för avlägsning av kakan (2) av fast material som bildas fr&n duken vid en bestämd,i dukens rörelseriktning efterföljande avlägsningsstation (5), kännetecknad därav, att anordningen omfattar tvA skilda matningsstationer (2) med efterföljande avlägsningsstationer (5), vilka är anordnade sä, att matningen av suspensionen (3) vid olika stationer sker tili olika sidor av duken (1), varvid vätskan som filtreras genom duken rengör den frän fast ämne som inte lösgjorts vid respektive föregäende avlägsningsstation (5).
