The cleaning device has cleaning elements for both sides of the screw vane and is guided both on the screw shaft (15) and on the inner wall (17) of the surrounding housing. The two guides are associated with each other by a joint with the interposition of an elastic connection. The cleaning device comprises a cleaning frame (1) guided both in a longitudinal groove (18) in the inner wall (17) of the housing and through a slide bearing on the screw shaft (15). The cleaning frame can comprise two parallel supports with scrapers and connected on the side facing the inner wall of the housing by a spacer so that protruding guide pieces are formed which are guided in the longitudinal groove of the inner wall. USE/ADVANTAGE - Effective cleaning to remove residues from all areas of the screw without dismantling the latter. For all types of industrial use.
