A system for cleaning a moving substrate includes a rail mounted adjacent to the substrate surface and substantially transverse to the direction of movement thereof. A carriage for supporting a contact cleaning roller (CCR) is deployed on the rail for allowing axial translation of the CCR transversely of the substrate while in rolling contact therewith. Two renewal stations for cleaning the CCR are mounted adjacent the rail, one outboard of each substrate edge. The CCR is at least twice as long as the width of the substrate and is axially oscillable for a distance sufficient that all portions of the CCR surface may be cleaned by the renewal stations during one oscillation cycle of the CCR while the CCR maintains continuous contact with the substrate across the full width thereof. The CCR mounted on the carriage may be a primary CCR and the substrate may be a continuous web or sheet, or the CCR mounted on the carriage may be a secondary CCR and the substrate may be a primary CCR or other process roller.
A system for cleaning particles from a first surface of a substrate moving along a conveyance path in a first direction, the substrate having a width transverse to the first direction and having first and second longitudinal edges parallel to said first direction, comprising:
A method for continuously cleaning a substrate surface moving in a first direction by rolling contact with a surface of a contact cleaning roller whilst simultaneously and continuously renewing the surface of the contact cleaning roller, the substrate width being defined by a distance transverse to the first direction between first and second parallel edges of said surface, comprising the steps of:
