Abstract

An air press for dewatering a paper web according to the present invention exhibits improved performance in the forming and pressing sections of a papermaking machine. The air press comprises a pressurized box which is positioned opposite a vacuum box. The pressurized box consists of a leading cross machine direction baffle with a ceramic shoe which engages a forming fabric and a trailing cross machine direction baffle of similar construction. The leading cross machine direction baffle presses against a resilient seal, causing a web contained between the upper and lower forming fabrics to wrap about the baffle shoe a few degrees to form an effective seal against air bypassing the baffle. The trailing cross machine direction baffle is positioned over a vacuum box which prevents air from leaking around the trailing baffle.
