Abstract
A seal used in an air press for dewatering a traveling paper web in a paper-making machine includes a support roll having a cylindrical surface, a belt and felt for supporting the paper web on either side thereof, an arm for mounting the seal, a seal body having a curved outer surface contour for substantially conforming to the curve of the cylindrical surface of the support roll, and an inner surface adjacent to the arm. A leading edge surface intersects with the curved outer surface, the leading edge surface defines the initial engagement with the traveling belt when in an operating position. A trailing edge surface intersects with the curved outer surface. The trailing edge surface defines, with the leading edge surface, the upstream and downstream bounds of the extended nip of the curved outer surface contour of the seal body over the support.
