Abstract
Abstract In a roller system including a rack assembly having spaced side carriers between which a plurality of pairs of rollers rotate and cooperate to drive a web, said rollers being rotatable between the side carriers within laterally spaced bearings. One movable bearing for each roller is carried within a slide bearing carrier which slidingly engages its associated side carrier to facilitate easy roller removal. The other bearing is fixed and is immovably held within the opposite side carrier by a bearing carrier.
