Abstract
A method and apparatus for providing uniform pressure, friction and/or contact between a substrate and a cylindrical roller in a brush-type cleaning system is described. The apparatus includes an alignment member adapted to allow pivotal movement of the cylindrical roller based on the topography of a substrate and/or the outer surface of the cylindrical roller. The method includes positioning a substrate between two cylindrical rollers, moving each of the two cylindrical rollers to a position where at least a portion of an outer surface of each of the cylindrical rollers are in contact with the major surfaces of the substrate, and rotating one or both of the substrate and the two cylindrical rollers relative to each other while allowing a longitudinal axis of one or both of the two cylindrical rollers to pivot relative to a plane defined by one of the major surfaces of the substrate.
