Abstract: Apparatus and method for cleaning conveyor systems, particularly for removing dust and other contaminants from optical processing equipment. A rigid or flexible sheet is coated on one or both faces with a tacky elastomer which is preferably a silicone. The sheet is moved over or through the conveyor system in place of a conveyed article, so that contaminants adhere to the elastomer and are ultimately removed from the conveyor along with the cleaning sheet. The invention is particularly applicable to cleaning conveyors transporting photographs and photo-tools, and to cleaning reprographic equipment incorporating paper transport rollers, eg photocopiers, facsimile machines, and desk-top printers.
