Abstract: An apparatus and method for conditioning a moving porous web on a papermaking machine is disclosed. The web has a first and a second surface and a high temperature gaseous boundary layer adjacent at least the second surface.

Abstract: The specification discloses embodiments of a process and related apparatus for conditioning a fibrous web in order to improve the efficiency of drying and calendering thereof. In the process, a moving fibrous web is conditioned after the drier unit of a papermaking machine by applying a flow of moistened gas through one or more arrays of radial jet reattachment nozzles placed in close proximity to the web surface prior to a calendering unit or prior to a steaming unit placed between the nozzles and the calender unit to cool the web and/or increase its moisture content. Webs treated according to the invention exhibit improved properties including less moisture streaking, enhanced smoothness and avoidance of optical property loss.
