Abstract
Apparatus and method for cleaning a flexible sheet moving along a travel path, such sheet including a leading edge extending transverse to the direction of sheet travel. A rotatable fibrous cleaning brush is located with its fibers intercepting the travel path of the moving sheet. Responsive to the approach of the leading edge of the sheet, a standing wave is generated in the fibers of the rotating brush. The standing wave results in the fibers being temporarily moved away from the travel path to enable the leading edge to pass substantially freely by such fibers. The fibers return substantially immediately into contact with the sheet after passage of the leading edge to clean the sheet including the area of the sheet adjacent to such edge.
