ABSTRACT:
An apparatus for processing a continuous web includes a plurality of rollers arranged for cooperative rotation. Each of the plurality of rollers have a first circular end surface, a second circular end surface and a cylindrical middle surface. The plurality of rollers define a corresponding plurality of nips. First and second sealing panels are provided for engaging the first and second circular ends of each of the plurality of rollers. The first and second sealing panels and the plurality of rollers define a chamber. The first and second sealing panels are structured and adapted to conform generally to the shape of the first and second circular end surfaces, respectively, of the plurality of rollers. End panel sealing of the chamber is provided by mechanical sealing, fluid sealing, or a combination thereof.
