Abstract
A device for removing dust from a moving paper web, where the dust is carried in a boundary layer of air that runs with the web, includes a first separating box mounted across the web running direction. The first separating box has a collecting duct extending across the web running direction, a curved guide surface which guides the paper web, and apparatus for deflecting the dust-laden air boundary layer into the collecting duct.
