Abstract

A photographic film or chip 11 is passed between counterrotating rollers 12 and 13 of cleaning apparatus 10. Film 11 is cleaned by wiping action between the two surfaces of such film and replaceable porous outer sleeves 14 of rollers 12 and 13. Air is drawn radially through sleeves 14 by maintaining reduced pressure within the perforated hollow shafts 15 and 16 to remove dirt and foreign particles dislodged from film 11.
