A web cleaner (20) is presented that removes debris that clings to the surface of a substrate in a printing process. The cleaner uses a number of idlers (26) holding a web (22) taut therebetween with the web driven at high speeds by a printing press (24). The cleaner utilizes a pair of counter rotating textured rollers (28) positioned between the idlers with one roller positioned on each side of the web in close proximity therewith and each roller rotates in an opposite direction to that of the webs flowpath. A air separating bar (36) is positioned at right angles to the web bordering each roller in adjacent relationship for directing the air into a plenum (44) that covers each roller and skiving bar. The plenum is used to collect the debris detached from the web surface by air currents formed by rotation of the rollers creating an air film on the web surface. The same air currents produce a positive air pressure within the plenum. A dust collector (50) is connected to each plenum for accumulating debris dislodged from the web surface.
