Abstract
A press roll system employed in connection with a web finishing assembly is provided. The press roll system includes a press roll, which cooperates with a head roll to provide a uniform nip area and pressing load; a support substrate, arranged between the ground and the press roll; at least one backup roller mounted to a first surface of the support substrate along a continuous axis for substantially the length of the press roll, and arranged to provide a uniform load to the press roll and uniform area between the press roll and head roll during operation to impart a uniform caliper to the web; and a retractable force actuator, mounted on a second surface of the support substrate, opposite the surface to which the backup rollers are mounted, to provide an even distribution of loads toward the press roll. A channel is attached to one end of the support substrate for receiving and channeling working fluid away from the rest of the press roll system.
