Abstract: A scraper for cleaning conveyor belts and the like includes an elongate blade holder with at least two support pins therein, and an elongate blade slidably received in a slot in the holder. The blade has an outer edge shaped for scraping a belt, and an inner edge abuttingly supported on the support pins at locations spaced a predetermined distance inwardly from the opposite ends of the blade. The blade is resiliently flexible along its length, such that as contact between the outer edge of the blade and the belt wears away the center portion of the blade, the end portions of the blade are flexed back about the support pins in the direction away from the belt, thereby bowing the center portion of the blade inwardly toward the belt for improved conformance and cleaning performance.
