To clean the interior of sacks (10) and especially container sacks (11), from clinging residual material at their inner sides (11'), where the sack has openings (3,5) at the opposite ends air is blown from one end (3) and the inner side (11') is scraped and beaten. Detached material from the inner side (11') is carried out of the sack by the blown air through the other opening (5). A fluid is sprayed against the inner side (11') of the sack (10), to increase the cleaning effect. An Independent claim is included for an assembly to clean container sacks, with a compressed air flow directed through one sack opening (3) towards the opposite opening (5). At least one beater and scraper is in the sack (10) to act on the inner sides (11'). Preferred Features: A projecting shaft is inserted into the sack (10), to rotate round its axis (A), with at least one flexible beating and scraping strip (30) secured at one end to the rotating shaft (20). The other end of the strip (30) beats against the inner side (11') of the sack (10) which is inflated by the compressed air flow through it. The end of the shaft (20) is short of the outlet opening (5), and has a number of beating and scraping strips (30). A fixed holder support (2) is inserted into one sack opening (3), with an external lock (4) to give a sealed fit of the opening edge on the support connection (40) to the air outlet (2) of the blower (1). The rotating shaft (20) passes through the center of the support connection (40). The rotating shaft (20) is tubular (21), closed at the far end. The shaft tube (21) has openings (18) distributed along its length to deliver a fluid medium from a rotating supply connection (16) at the open end. The beating and scraping strips (30) have belts (31) or chains or hoses. The hoses are fitted at the shaft tube outlet openings at one end, and are open at their other end. At least two beating and scraping strips (30) are linked together at their free ends by longitudinal link members. The far end opening (5) of the sack (10) is fitted to a separator (8), where the detached clinging material mixture is collected and sorted.
