A conveyor belt cleaning device provides a belt scraper blade and a roller juxtaposed to the blade on its downstream side, relative to the direction of conveyor belt travel. Frictional contact between the moving conveyor belt and roller drives the roller. The scraper blade scrapes stringy materials from the belt and the roller pinches trailing stringy materials between the belt and the roller, pulling such materials from the blade.
