Abstract:
A method for continuously cleaning a moving substrate surface by rolling contact with a surface of a contact cleaning roller and simultaneously and continuously renewing the surface of the contact cleaning roller, comprising the steps of:a) providing a contact cleaning roller at least twice as long as the width of said substrate; b) engaging said contact cleaning roller surface in rolling contact with said moving substrate surface to clean said substrate surface; c) providing first and second renewal stations adjacent opposite edges, respectively, of the substrate; d) engaging at least one of said renewal stations in renewal contact with said contact cleaning roller; e) axially oscillating said contact cleaning roller transversely of said substrate surface during said rolling contact therewith by an oscillatory distance sufficient that at least one half of said contact cleaning roller surface is renewed by each one of said renewal stations during one complete cycle of said oscillation; and f) engaging both of said first and second renewal stations with said contact cleaning roller.
